TRAYNOR, Justice: 
 
Murad Diggs was convicted in the Superior Court of possession of a firearm 
by a person prohibited and possession of ammunition by a person prohibited.1  In 
this direct appeal, Diggs claims that the Superior Court erred when it denied his 
motion to suppress the evidence seized from him—the firearm and ammunition—
following an investigative detention and frisk that was, in Diggs’s view, unsupported 
by reasonable suspicion.  More specifically, Diggs challenges the court’s conclusion 
that the tip upon which the police were acting came from a “citizen informant” and 
therefore was presumptively reliable.  Diggs also contends that the Superior Court’s 
suppression-hearing factual determinations were flawed because the court failed to 
draw a “lost and/or missing evidence”2 inference as a result of the police’s failure to 
collect and preserve certain evidence. 
 
Although we agree, in part, with Diggs’s criticism of the Superior Court’s 
“citizen-informant” analysis, we disagree with his conclusion that his seizure was 
not supported by sufficient reasonable suspicion.  Likewise, we reject Diggs’s 
contention that the Superior Court’s failure to draw an adverse inference against the 
 
1 According to Diggs’s notice of appeal, his appeal encompasses a drug-dealing conviction in a 
separate prosecution under a separate indictment.  But Diggs’s briefs make no mention of the facts 
surrounding his drug-dealing conviction, nor do his legal arguments touch upon that charge.  We 
therefore assume that the inclusion of that conviction in the notice of appeal was unintentional or, 
if it was not, that Diggs has abandoned that aspect of his appeal.

prosecution—an inference that Diggs did not urge the court to draw in the 
proceedings below—was plainly erroneous.  Hence, we affirm. 
I. 
A. 
 
On the date of Diggs’s arrest, Corporal Alexander Marino of the Wilmington 
Police Department received a call from a “concerned citizen” on his personal cell 
phone.3  The caller informed Corporal Marino that a “black male, approximately 30 
to 35 years of age . . . wearing a camouflage jacket, had a small handgun on [sic] his 
waistband”4 in the 200 block of South Harrison Street in Wilmington. 
 
The caller was not a stranger to Corporal Marino; in fact, Corporal Marino 
had known the caller for 11 years during which the caller had provided information 
relating to criminal activity approximately five times.  Corporal Marino offered that, 
on at least some of those prior occasions, the caller’s information was reliable and 
led to arrests of different individuals.   
 
On this particular occasion, though, Corporal Marino was not on duty so he 
relayed the information to an on-duty officer—Patrolman Raymond Shupe—who 
was near the area described by the caller.  Because the Wilmington Police 
Department does not provide its officers with cell phones, the conversation between

Corporal Marino and Patrolman Shupe was held on the officers’ personal cell 
phones.  Shupe recalled that he also received a text message from Marino that day, 
but Marino testified he “did not text [Shupe] with any information about the 
informant.”5  The State did not produce any cell phone data from which it could be 
determined if, when, and how Marino communicated with Shupe because Marino 
“clean[s] [his] phone out,”6 that is, deletes his messages, every week.   
 
Patrolman Shupe shared the substance of Marino’s message with his partner 
and called other officers for back-up.  Soon thereafter, Shupe observed a black male 
meeting the informant’s description—eventually identified as Murad Diggs—
wearing a camouflage jacket walking in a southerly direction on South Harrison 
Street.  Diggs, it turns out, was then 36 years old, barely outside the age range 
provided by the informant.  As Diggs entered a convenience store, known as the 
Shop Smart Market, on the corner of Elm and South Harrison Streets, Patrolman 
Shupe parked his marked police vehicle and, recognizing that he might be 
confronting an armed person, waited for his back-up to arrive.  When two back-up 
officers arrived, the four police officers—Shupe, his partner, and the two back-up 
officers—approached the store.  All four were in Wilmington Police Department 
uniforms.

As Patrolman Shupe entered the store, he immediately encountered Diggs, 
who was leaving, in the doorway.  At that moment, according to Patrolman Shupe, 
he intended to engage in a “consensual encounter.”7  During his suppression hearing 
testimony, Patrolman Shupe described his approach to Diggs as well as Diggs’s 
reaction: 
Q. 
What happened as you were attempting to enter the store and he 
attempting to exist the store? 
A. 
I asked if I could speak with him. 
Q. 
What, if anything, did you ask him? 
A. 
I just asked if I could speak with him. 
Q. 
Why did you ask him that? 
A. 
Because I had to get reasonable articulable suspicion that he had 
a firearm before I acted on it. 
Q. 
Was your intention to engage in a consensual encounter? 
A. 
That was my intention. 
Q. 
What happened when you asked Mr. Diggs can I speak with you? 
A. 
He had his cell phone in one hand and a cigar in the other hand, 
and he threw them on the ground immediately, got into a defensive 
stance and started backing away, he looked left and right like he was 
going to run or fight.8 
 
 
The force with which Diggs threw his phone to the ground was “significant,”9 
leading Shupe to believe that “he was trying to break it.”10  And his training and

experience in the use of firearms suggested to Shupe that the stance assumed by 
Diggs was “a good place to start to draw a firearm.”11  Based on these factors and 
Shupe’s belief—prompted by what Corporal Marino had told him—that Diggs 
possessed a firearm, Shupe “took a step forward and . . . grabbed a hold of  . . . 
Diggs’[s] arm[,]”12 for the purpose of “check[ing] for potential weapons.”13  But 
Diggs did not cooperate, and a struggle ensued. 
 
In the struggle, Diggs “began pushing and pulling to get away from 
[Shupe].”14  Two of the other officers came to Shupe’s aid, eventually taking Diggs 
to the floor and placing him in handcuffs.  Patrolman Shupe then conducted a pat-
down search of Diggs for weapons and found a loaded handgun in Diggs’s 
waistband.  After this encounter, Patrolman Shupe asked the person behind the 
store’s counter for access to any video recordings that might have been captured by 
the store’s security cameras, but that employee didn’t know how to work the 
cameras.15 
 
Patrolman Shupe placed Diggs under arrest for carrying a concealed deadly 
weapon (“CCDW”) and resisting arrest.  Two months later, Diggs was indicted for

same response—the store employee that day did not know how to operate the cameras, and Shupe 
left empty-handed.  Id. at A74, A89.

those same charges, but also—because of a prior felony conviction—for possession 
of a firearm by a person prohibited (“PFBPP”) and possession of ammunition by a 
person prohibited (“PABPP”). 
B. 
 
Diggs moved the Superior Court to suppress the evidence of the loaded 
firearm on the grounds that it was obtained in violation of his rights under the Fourth 
and Fourteenth Amendments of the United States Constitution and Article I, Section 
6 of the Delaware Constitution.  More specifically, Diggs contended that Patrolman 
Shupe’s investigatory stop was unlawful because the officer did not have a 
reasonable articulable suspicion to justify that intrusion.  The State responded that 
the totality of the circumstances, which included “the eyewitness’s information, 
Officer Shupe’s observations of the Defendant’s suspicious behavior, Officer 
Shupe’s training and experience, and the high crime area, when viewed through the 
eyes of a reasonable police officer constituted reasonable articulable suspicion that 
the Defendant was committing a crime, specifically CCDW.”16  Likewise, the State 
argued that Patrolman Shupe’s frisking of Diggs was justified because Shupe 
reasonably suspected that Diggs was armed and presently dangerous.

C. 
 
At the hearing on Diggs’s motion to suppress, Corporal Marino and Patrolman 
Shupe testified for the prosecution and described, respectively, Marino’s receipt and 
transmission of the informant’s tip and Shupe’s response to the tip and encounter 
with Diggs as outlined above.  For his part, Diggs presented four witnesses, two of 
whom were in the store during the encounter and two—Diggs’s sister and mother—
who were near, but outside, the store. 
 
On the day of Diggs’s arrest, Guy Bullock was working as a cook in the store’s 
kitchen, which is approximately 30 to 45 feet from the store’s front door.  At his 
boss’s request, Bullock moved toward the front of the store.  It was a particularly 
hectic day, and Bullock’s boss was concerned with “[p]otential shoplifting[] and the 
store being overcrowded.”17  While in the front of the store, Bullock focused on the 
“kids” there, interacting with those who presented a shoplifting risk. 
 
Around that time, Bullock saw somebody grab Diggs’s arm and pull him away 
as he opened the door to leave the store.  At first, Bullock didn’t know, despite 
Patrolman Shupe’s uniform, that the person grabbing Diggs’s arm was a police 
officer.  In fact, he “thought it was getting ready to be a fight, so [he] moved [a] kid 
out of the way.”18  As these events unfolded—according to Bullock, “[e]verything 
 
17 Id. at A109. 
18 Id. at A114. 
 
9 
 
happened quickly”19—Bullock was “paying attention to the kids and was looking at 
the door”20 as Diggs reached for it.  Before Diggs’s arm was grabbed, Bullock did 
not hear Patrolman Shupe say anything to Diggs nor did he see Diggs throw 
anything. 
 
Andrea Price, a neighborhood resident, was also in the store when Diggs 
encountered Patrolman Shupe and confirmed that the store was crowded that day.  
She was behind Diggs as he opened the door to leave the store.  Price “remember[ed] 
an officer grabbing [Diggs’s] arm . . . and pulling his arm back. . . . [A]t that point[,] 
[Price] turned around and tried to get out of the way.”21  Price added that, after she 
saw the officer grab Diggs’s arm, Diggs “put his hands up” and then saw him 
“detained on the floor.”22  Price was unable to describe the “three or four” officers 
she saw at the store that day because “[e]verything . . . happened so fast.”23 
 
The court next heard from Na’Isha Pantoja, Diggs’s sister, who was outside 
the store.  Na’Isha confirmed that her brother’s encounter with the police officers 
occurred as Diggs was exiting and the officers were entering the store.  As she 
approached the store with her children, Na’Isha saw a police officer grab Diggs and

10 
 
take him to the ground.  After that, according to Na’Isha, the police searched Diggs 
20 to 30 times. 
 
When asked whether she heard Diggs say anything to the officer, Na’Isha first 
said that she did not know but then offered that Diggs “might have said” he had “his 
ID or something” though she wasn’t “too for sure.”24  Na’Isha did not hear the officer 
say anything to her brother, nor did she see her brother throw anything. 
 
Na’Isha also noted that she saw a “little light skin boy . . . [in a] fatigue 
jacket”25 similar to the jacket Diggs was wearing leaving the store.  It is unclear 
whether she saw this individual before or after she saw her brother’s encounter with 
Patrolman Shupe.  Na’Isha estimated that this “boy” was in his mid-20’s; as 
mentioned, Diggs was 36 years old at the time. 
 
Finally, in what must have come as a surprise, during cross-examination, 
Na’Isha disclosed that she recorded the incident on her cell phone.  Again, the record 
is unclear when Na’Isha began to record the incident, but, in any event, the defense 
did not play the video during the suppression hearing. 
 
Diggs’s final witness at the hearing was his mother, Julia Pantoja.  Like 
Na’Isha, Julia observed the event from outside the store.  The first thing Julia noticed 
 
24 Id. at A138. 
25 Id. at A137. 
 
11 
 
as she saw the police officers approaching the store was “a couple of guys coming 
out”26 of the store, one of whom was wearing a camouflaged jacket.  Julia agreed 
with Na’Isha’s assessment that this other person was “[m]aybe about 25.”27 
 
According to Julia, as her son was leaving the store about the same time as 
the officers—she recalled that there were six or seven officers—were trying to enter, 
“it looked like it was a tug of war, [and] the officers grabbed [Diggs’s] arm.”28  She 
did not hear the officer say anything before he grabbed Diggs’s arm.  Like Diggs’s 
other witnesses, Julia did not see Diggs throw anything.  Lastly, Julia provided a 
more conservative estimate of the number of searches conducted by the police during 
Diggs’s detention; she recalled that “[t]hey searched [Diggs] about six to seven 
times.”29  
D. 
 
In the Superior Court, Diggs classified Marino’s informant as an anonymous 
informant whose information was too vague to justify Patrolman Shupe’s seizure of 
him—a seizure that Diggs claimed occurred immediately, “before any of [his] 
 
26 Id. at A154. 
27 Id. at A161. 
28 Id. at A155. 
29 Id. at A157. 
 
12 
 
actions after the police arrived [at] the convenience store.”30  And, according to 
Diggs, because the informant did not share with Marino the basis of her knowledge 
that the person she was reporting was armed, the reliability of her tip was further 
undermined.  
 
The State countered that the totality of the circumstances, when viewed 
through the eyes of a reasonable police officer, supported Patrolman Shupe’s 
suspicion that Diggs was unlawfully carrying a concealed deadly weapon.  Those 
circumstances included the information provided by the informant,31 Patrolman 
Shupe’s training and experience, and the fact that the 200 block of South Harrison 
Street is a “high crime area.”32  In responding to Diggs’s attack on the reliability of 
the informant’s tip, the State invoked the informant’s status as a “concerned citizen,” 
who, under a line of cases including Bailey v. State,33 and Hooks v. State,34 should 
be considered presumptively reliable.

Apr. 1, 2019); see also id. at 21 (“[Diggs’s] position is . . . that the evidence shows that the officer 
went to the corner store, Mr. Diggs opened the door, and the officer grabbed Mr. Diggs’s arm.”). 
31 The State’s March 22, 2019 Response to Defendant’s Motion to Dismiss describes the informant 
as an “eyewitness.”  App. to Opening Br. at A26.  But Corporal Marino’s suppression-hearing 
testimony indicated only that he had “received information from . . . a concerned citizen that an 
individual in the area of the 200 block of South Harrison was in possession of a handgun.”  Id. at 
A42.  Marino offered no insight into how the informant learned these purported facts as Diggs 
pointed out in his argument below.

E. 
 
The resolution of the issues presented to Superior Court depended in large part 
on whether Diggs was seized for Fourth Amendment purposes before or after he 
threw his phone and cigar down and assumed a defensive stance.  It was therefore 
necessary for the court to untangle the varying accounts of what happened at the 
store’s entrance that day.  The Superior Court succinctly resolved “the relevant 
inconsistencies”: 
The Court understands from all of the testimony that the encounter 
between Officer Shupe and Mr. Diggs happened fast over a few 
seconds.  In addition, given the narrow aisles at the Market, no witness 
at the Hearing had a clear view of the face to face interaction between 
Officer Shupe and Mr. Diggs other than Officer Shupe.  Mr. Bullock 
was behind Mr. Diggs and, at the request of management, talking to 
some boys in the shop. Ms. Pierce was also behind Mr. Diggs.  
Although not dealing with customers like Mr. Bullock, Ms. Pierce is 10 
inches shorter than Mr. Diggs and necessarily had her view of the face-
to-face encounter between Officer Shupe and Mr. Diggs blocked by Mr. 
Diggs.  Na’Isha and Juli[a] Pantoja were outside the Market and were 
restricted in their view of the encounter by Officer Shupe and the 
additional WPD officers at the scene.  Under these circumstances, the 
Court would expect the testimony to differ as to what exactly happened 
between Officer Shupe and Mr. Diggs.  
 
Officer Shupe was in an area that had recently experienced a 
shooting and an incident involving Molotov cocktails.  The citizen 
informant provided that Mr. Diggs had a concealed firearm.  According 
to Officer Shupe, Officer Shupe tried to talk to Mr. Diggs but, after 
asking to speak with him, Mr. Diggs reacted in a manner that Officer 
Shupe had never seen before.  Mr. Diggs threw down the items in his 
hands, got into a defensive position and took steps backwards.  At this 
point, Officer Shupe believed that Mr. Diggs had a gun and grabbed 
 
14 
 
him to check for weapons.  A struggle ensued, other WPD officers 
joined in and a loaded handgun was found in Mr. Diggs’[s] waistband.35 
 
The Superior Court’s legal analysis proceeded from the premise that the tip 
received by Corporal Marino, who passed it along to Patrolman Shupe, was provided 
by a “citizen informant” and therefore was presumptively reliable.  Given that and 
Patrolman Shupe’s observation of an individual matching the informant’s 
description in the location identified by the informant, the court found that “Shupe 
had a particularized and objective basis to suspect that Mr. Diggs was committing a 
crime—possible possession of a firearm without a license or, if hidden, carrying a 
concealed deadly weapon.”36  This, according to the court, justified Patrolman 
Shupe’s stop of Diggs.  The court then shifted its focus to whether Patrolman Shupe 
could frisk Diggs.  Based upon the factual findings set forth above, the court was 
satisfied that the frisk was justified.  Therefore, the court denied Diggs’s motion to 
suppress. 
 
And, based on those findings, the Superior Court concluded that Patrolman 
Shupe had made a reasonable investigatory stop and did not overstep constitutional 
bounds when he conducted a limited protective search of Diggs’s person for 
weapons.  Therefore, the court denied Diggs’s motion to suppress.

F. 
 
After the CCDW and resisting-arrest counts were severed, Diggs proceeded 
to trial on the PFBPP and PABPP counts.  The jury found Diggs guilty on both 
counts, and the court sentenced him to 18 years at Level V incarceration suspended 
after 10 years for 18 months of Level III intensive supervision.37  Diggs then 
appealed. 
G. 
 
Broadly speaking, Diggs raises two issues on appeal.  First, he challenges the 
Superior Court’s finding that Patrolman Shupe had a sufficiently particularized and 
objective basis to detain him.  In particular, Diggs contests the court’s invocation of 
the “citizen informant” doctrine in its analysis of the reasonableness of the officers’ 
seizure of Diggs.  Diggs also claims that the court’s factual findings regarding his 
reaction to Shupe’s otherwise lawful approach were based on “an erroneous review 
of the totality of the evidence and an unjustifiable disregard of contrary facts.”38  
Second, Diggs argues—for the first time on appeal—that, when the Superior Court 
made its suppression-hearing factual findings, it should have drawn an inference 
adverse to the prosecution because it did not preserve and disclose information from

the officers’ cell phones and video surveillance evidence that might have captured 
Diggs’s encounter with the police. 
II. 
 
This Court reviews a trial judge’s denial of a motion to suppress for an abuse 
of discretion.39  Our review of the trial court’s legal conclusions, however, is de 
novo.40  When the trial court denies the motion after an evidentiary hearing, our 
review of its factual findings is deferential; the inquiry is whether there was 
sufficient evidence to support those findings and whether they were clearly 
erroneous.41 
 
Diggs’ evidentiary argument—that the Superior Court was required to apply 
a “‘lost and/or missing evidence’ inference”42 to its suppression-hearing factual 
findings—was not raised in the Superior Court.  Under this Court’s rules, “[o]nly 
questions fairly presented to the trial court may be presented for review.”43  In other 
words, an argument not made in the trial court is deemed to have been waived.  
“[We] may excuse a waiver, however, if [we] find[] that the trial court committed 
plain error requiring review in the interests of justice.”44  “Plain error is limited to

material defects . . . apparent on the face of the record; . . .  basic, serious and 
fundamental in their character, . . . [that] clearly deprive an accused of a substantial 
right, or which clearly show manifest injustice.”45 
III. 
 
The Fourth Amendment protects the citizenry from unwarranted 
governmental searches and seizures.  Likewise, Article I, § 6 of the Delaware 
Constitution provides that “[t]he people shall be secure in their persons, houses, 
papers and possessions, from unreasonable searches and seizures.”46  Under the 
exclusionary rule, evidence obtained by searches and seizures that violate these 
guarantees is inadmissible.47  Diggs claims that the police unjustifiably seized him 
during the store encounter and that, therefore, the evidence obtained as a result of 
the seizure, i.e., the gun and ammunition, should have been suppressed under the 
exclusionary rule. 
 
Generally speaking, investigative encounters between law enforcement and 
citizens fall within three categories:  consensual encounters or mere inquiries, 
 
45 Wainwright v. State, 504 A.2d 1096, 1100 (Del. 1986). 
46 Del. Const. art. I, § 6. 
47 Mapp v. Ohio, 367 U.S. 643, 654 (1961) (“[A]ll evidence obtained by searches and seizures in 
violation of the Constitution is inadmissible in a state court.”); Jones v. State, 745 A.2d 856, 872 
(Del 1999)  (“The exclusionary rule acts as a remedy for a violation of a defendant’s right to be 
free of illegal searches and seizures.  It provides for the exclusion from trial of any evidence 
recovered or derived from an illegal search and seizure.”). 
 
18 
 
investigative detentions, and formal arrests.  The category into which an encounter 
fits depends on the nature and extent of the contact.  A consensual encounter would 
include—as happened initially here—a police officer asking the citizen a question.  
Such an encounter is not a seizure under the Fourth Amendment or Article I, § 6 of 
the Delaware Constitution and therefore no level of suspicion is required to support 
it.  As the United States Supreme Court put it in Florida v. Royer 
law enforcement officers do not violate the Fourth Amendment by 
merely approaching an individual on the street or in another public 
place, by asking him if he is willing to answer some questions, by 
putting questions to him if the person is willing to listen, or by offering 
in evidence in a criminal prosecution his voluntary answers to such 
questions.48 
 
The next level of encounters—investigative detentions—are more intrusive 
and are considered seizures under the Fourth Amendment and Article I, § 6.49  
Typical investigative detentions include motor-vehicle stops and stops of persons 
who are “abroad[] or in a public place.”50  Under Section 1902(c) of the Delaware 
Criminal Code, such a detention “shall not exceed 2 hours . . .  [and] is not an 
arrest.”51  Under Delaware law, an arrest “is the taking of a person into custody in 
 
48 Florida v. Royer, 460 U.S. 491, 499 (1983); see also Woody v. State, 765 A.2d 1257, 1283 n.3 
(Del. 2001).

order that the person may be forthcoming to answer for the commission of a 
crime.”52   
 
In this case, Superior Court found—and the parties do not dispute—that, when 
Patrolman Shupe grabbed Diggs by the arm, Shupe transformed a consensual 
encounter into an investigative seizure.  Thus, under both federal and Delaware 
constitutional law, it was incumbent upon Shupe “to point to specific and articulable 
facts which, taken together with rational inferences from those facts, reasonably 
warrant [the] intrusion.”53  In this Court’s words, an investigative detention “must 
be justified at its inception by reasonable suspicion of criminal activity as defined in 
Terry v. Ohio.”54  “A determination of reasonable suspicion must be evaluated in the 
context of the totality of the circumstances as viewed through the eyes of a 
reasonable, trained police officer in the same or similar circumstances, combining 
objective facts with such an officer’s subjective interpretation of those facts.”55 
 
This level of justification is often referred to as “reasonable articulable

Supreme Court observed that “the concept . . . , like probable cause, is not ‘readily, 
or even usefully, reduced to a neat set of legal rules.’”57 
A. 
 
Diggs now mounts a five-fold challenge to the Superior Court’s determination 
that Patrolman Shupe’s detention of Diggs was supported by a reasonable articulable 
suspicion.  First, Diggs claims that the court’s conclusion that Marino’s informant 
qualified as a “citizen informant” whose tip was presumptively reliable was 
erroneous.  Second, he contends that the presumption of reliability afforded to the 
informant’s tip is an impermissible conclusive presumption under 11 Del. C. § 306.  
Third, Diggs argues that the absence of any information about the informant’s basis 
of knowledge—that is, how the informant came to know that the individual she 
described was concealing a handgun in his waistband—rendered her tip unreliable.  
Fourth, Diggs contends that Patrolman Shupe was not entitled to rely on the 
information from Corporal Marino as the “sole basis”58 to stop Diggs.  And fifth, 
Diggs challenges the Superior Court’s finding that Diggs engaged in suspicious 
 
informant’s tip that is “insufficient for . . . [an] arrest or search warrant” may nonetheless carry a 
sufficient indicia of reliability for an investigative detention).

behavior when Patrolman Shupe asked him if he was willing to speak with him 
thereby providing the basis to conduct a limited search for weapons.   
B. 
 
Because our analysis of Diggs’s legal arguments is largely driven by the facts, 
we take up Diggs’s challenge to the Superior Court’s factual findings first.  The 
thrust of Diggs’s complaint is that the court should have credited the testimony of 
Bullock and Price, to the exclusion of Patrolman Shupe’s testimony, on two 
important points.  Specifically, Diggs notes that Bullock did not hear the officer say 
anything before grabbing Diggs’s arm, and neither Bullock nor Price saw Diggs 
throw anything.  Thus, according to Diggs, the court should have rejected Patrolman 
Shupe’s testimony that Diggs engaged in suspicious behavior, forcefully throwing 
down his phone and cigar and assuming a defensive stand “like he was going to run 
or fight,”59 in response to Shupe’s casual question.   
 
As mentioned before, our review of the factual findings of the Superior Court, 
following an evidentiary hearing on a motion to suppress is deferential.60  Findings 
on credibility determinations, are subject to the “clearly erroneous” standard.61  And

22 
 
“[w]here there are two permissible views of the evidence, the factfinder’s choice 
between them cannot be clearly erroneous.”62 
 
Here, the record supports two permissible views of the evidence as it related 
to whether Shupe first asked to speak with Diggs and whether and to what extent 
Diggs reacted strangely to Shupe’s approach, including whether Diggs threw items 
to the floor and assumed a position indicative of an intent to fight or flee before 
Shupe grabbed him by the arm.  Shupe, recognizing that armed with the tip alone, 
he needed “to get reasonable articulable suspicion that [Diggs] had a firearm before 
[he] acted on it,”63 said that he intended to engage in a consensual encounter with 
Diggs.  But as soon as he asked Diggs if he could speak with him, Diggs responded 
in a way that led Shupe to believe, based on his training and experience, that Diggs 
not only might “run or fight” but that he might have been preparing to draw a 
weapon.64 
 
To be sure, Diggs’s witnesses perceived the event differently and in a way 
that could cause a fact-finder to doubt whether Patrolman Shupe said anything to 
Diggs before grabbing him and whether Diggs behaved precisely as Shupe 
described.  But each of those witnesses were subject to limitations on their ability to

63 App. of Opening Br. at A67. 
64 Id. at A67–68. 
 
23 
 
see and hear what happened, and some were members of Diggs’s immediate family.  
For instance, Bullock, who testified that he did not hear Patrolman Shupe say 
anything to Diggs and did not see Diggs throw anything, acknowledged that his 
attention was divided between the suspected shoplifters in the store and the 
encounter in the store’s doorway.  Price, who, like Bullock did not hear anyone say 
anything to Diggs and did not see Diggs throw anything, was behind Diggs and 
therefore had an obstructed view of the police officers.  As Price recalled, 
“[e]verything . . . happened so fast, so . . . [she didn’t] quite recall seeing [the 
officers’] faces.”65  And the testimony of Na’Isha and Julia Pantoja—Diggs’s sister 
and mother, respectively, and thus vulnerable to a charge of bias—was hampered by 
the fact that neither was inside the store. 
 
Under these circumstances, we cannot conclude that the Superior Court’s 
adoption of Patrolman Shupe’s version of the encounter was clearly erroneous.  To 
be clear, had the court rejected Patrolman Shupe’s version and credited the equally 
permissible view of the evidence Diggs favored, we could not conclude that such a 
choice was clearly erroneous.  But when presented with differing accounts of 
historical facts, “it is the [trial court’s] role to resolve the conflicts in witnesses’ 
testimony and weigh their credibility.”66  In this case, the trial court thoughtfully

24 
 
weighed the witnesses’ competing versions and made findings that were supported 
by sufficient evidence.  Consequently, we reject Diggs’s claim that those findings 
were erroneous.   Those findings, moreover, undercut Diggs’s legal arguments 
which, to the extent necessary, we now take up in turn. 
C. 
 
The central thrust of the legal arguments Diggs presses on appeal—as 
distinguished from his criticism of the court’s factual findings discussed above—is 
that the Superior Court misapplied the so-called “citizen informant” doctrine when 
it assessed the reasonableness of Patrolman Shupe’s conduct.  Diggs leads with the 
assertion that Corporal Marino’s informant was not in fact a citizen informant as that 
term has been defined and follows with a critique of the reliability of the informant’s 
tip and Patrolman Shupe’s minimal corroboration of it. 
 
In contrast to the showing of credibility or reliability that is required when 
evaluating a typical informant’s tip, under the “citizen informant” doctrine, the 
reliability of information provided by “an average law abiding citizen performing a 
civic duty by reporting a crime”67 is sometimes presumed.  “The citizen-informer is 
a passive observer with no connection with the underworld, and no reason to 
fabricate what he has seen or heard, and as such is considered presumptively 
 
67 Bailey, 440 A.2d at 999. 
 
25 
 
reliable.”68  The most typical application of this presumption of reliability involves 
a “person appearing to be an average citizen [who] takes the initiative in 
communicating to the police the fact that he has been a victim or a witness to a crime 
such as robbery or assault.”69 
 
In our view, Diggs rightly questions whether the suppression-hearing record 
supports the Superior Court’s finding that Corporal Marino’s informant “was not a 
member of the criminal community, but rather an individual who occasionally 
telephoned police to report incidents of which he or she had knowledge.”70  Although 
Corporal Marino described the informant as a “concerned citizen,”71 he did not 
confirm that the informant was not of the criminal milieu.  Additionally, it is 
unclear—despite the State characterization of the informant as an “eyewitness”72—
whether the informant witnessed the described person possessing the firearm as 
reported.   
 
These gaps raise legitimate questions about the applicability of the “citizen 
informant” doctrine here.  What is more, the informant’s possession of Corporal 
Marino’s personal cell phone number and her history of providing several tips over

26 
 
a period of 11 years sets this informant apart from the typical “citizen informant.”  
Yet because, as we explain below, the legality of the seizure of Diggs’s gun does not 
turn exclusively on the reliability of the informant’s tip, we need not answer those 
questions.  The pertinent question instead is whether the additional facts that came 
to light after Corporal Marino relayed the tip to Patrolman Shupe sufficiently 
bolstered the tip regardless of the tipster’s classification.  The question asked 
differently is:  even if we were to accept Diggs’s contention that Corporal Marino’s 
tipster must be treated as an anonymous informant whose information is not 
presumed to be reliable, did Patrolman Shupe’s later observations, coupled with the 
tip and the minimal corroboration of it, create a reasonable suspicion of criminal 
activity?  Our answer is yes. 
 
Before explaining this answer, we note that Diggs never confronts this issue 
on these terms.  Instead, he argues that Patrolman Shupe relied on the informant’s 
tip, as relayed to him by Corporal Marino, as the “sole basis” for stopping Diggs.73  
Diggs doubled down on this assertion at oral argument, claiming that “[t]his was all 
driven by the tip and [that] this case is really about the tip and whether it provided 
reasonable suspicion.”74  Alternatively, Diggs depicts his reaction to Patrolman

Shupe as merely “act[ing] in a way to avoid speaking to the police.”75  But we have 
already rejected Diggs’s invitation to reduce the totality of the circumstances upon 
which Patrolman Shupe based his decision to detain Diggs to the informant’s tip.  
And Diggs’s watered down description of his reaction to Shupe’s approach cannot 
be squared with Shupe’s description of the encounter—a description the trial court 
credited and upon which we base our ensuing analysis.   
D. 
 
That the police seized Diggs, within the meaning of the Fourth Amendment 
and Article I, § 6, in the entrance way of the store is not disputed.  The parties’ 
positions are less clear, however, as to when the seizure took place.  The Superior 
Court found—and the State seems to concede—that Patrolman Shupe seized Diggs 
when, after Diggs threw down his phone and cigar and assumed a defensive stance, 
Shupe grabbed Diggs by the arm.  For his part, in his briefs, Diggs assiduously 
avoids identifying the point at which the encounter turned into a seizure.  Yet Diggs 
conceded at oral argument that Patrolman Shupe’s initial approach and inquiry of 
Diggs did not constitute a seizure,76 and nowhere does he contest the trial court’s 
 
75 Opening Br. at 36. 
76 Oral Argument Transcript, May 26, 2021.  
 
 
28 
 
determination that the seizure occurred when Shupe grabbed Diggs’s arm.  
Consequently, our analysis focuses on the quantum of information Shupe possessed 
at that time in determining whether Diggs’s detention was warranted.   
 
The evidentiary record supports the conclusion that the following specific and 
articulable facts were known to Patrolman Shupe before he detained Diggs.  
Corporal Marino had informed Shupe that a reliable witness had told him that a 
Black male, approximately 30 to 35 years of age and wearing a camouflage jacket, 
was on the 200 block of South Harrison Street, which Shupe described as “a high 
crime area.”77 According to the tip as relayed by Marino, the described individual 
was “armed with a handgun, and it was in his waistband.”78 
 
Shupe responded to the area “very quickly”79 and observed an individual—
Diggs—walking in a southerly direction on Harrison Street.  Shupe watched as 
Diggs entered the Shop Smart convenience store and eventually followed him there, 
encountering Diggs in the doorway.  There were several people, including children, 
in the front of the store near the doorway. 
 
Justice Traynor:  Would you agree that neither the Fourth Amendment or Article I, 
Section 6 of the Delaware Constitution prohibited Officer Shupe from approaching 
Mr. Diggs and asking to speak with him? 
Counsel for Diggs:  I agree.

When Shupe asked Diggs if he could speak with him, Diggs forcefully threw 
down his cell phone and also discarded a cigar.  Then Diggs assumed an odd stance, 
which Shupe described alternatively as “defensive”80 and “athletic.”81  Based on his 
training and experience, Shupe inferred that Diggs “was going into flight or fight 
mode”82 and had placed his hands in “a good place to start to draw a firearm.”83  At 
that point, Shupe’s belief that Diggs possessed a firearm solidified, and he “grabbed 
a hold of Mr. Diggs’[s] arm . . . to detain him . . .  [for] further . . . investigation.”84 
 
That these facts, viewed in their totality, justified Patrolman Shupe’s 
investigative detention of Diggs seems evident to us.  One simple way to reach that 
conclusion is to ask what Shupe was to do at each step along the way.  Was it 
improper for the officer to follow up on the tip by responding to the designated area 
to determine whether an individual meeting the tipster’s description would be found 
there?  Of course not.  Upon seeing such an individual there, was it unlawful for 
Shupe to approach him and ask if the two might talk?  Diggs himself answers this 
question in the negative.  So we are left with assessing the reasonableness of 
detaining an individual who reportedly possesses a weapon in a crowded 
convenience store and who reacts to a lawful inquiry by a uniformed police officer

not by declining, politely or otherwise, to speak with the officer but by acting in a 
way that could be interpreted as aggressive, if not dangerous.  Under these 
circumstances, it was reasonable, in our view, for Shupe to suspect that the 
informant’s tip was credible and that Diggs was armed or otherwise engaged in 
criminal activity.85  Hence, the detention was reasonable and did not constitute a 
violation of Diggs’s constitutional rights. 
 
It follows from this conclusion that Patrolman Shupe’s protective search of 
Diggs’s person for weapons was lawful.86  Diggs does not argue otherwise.87 
E. 
 
Our determination that the Superior Court’s factual findings were supported 
by sufficient evidence and not clearly erroneous and our conclusion that, even in the 
absence of the presumption of reliability assigned to the purported “citizen 
 
85 To be clear, we do not hold today that the informant’s tip, standing alone, justified the detention 
of Diggs, only that the tip, coming as it did from an informant with whom Corporal Marino was 
familiar and who had previously supplied reliable information, was not entirely devoid of value 
and was worthy of consideration under the “totality of the circumstances” test. 
86 11 Del. C. § 1903 (“A peace officer may search for a dangerous weapon any person whom the 
officer has stopped or detained to question as provided in § 1902 of this title, whenever the officer 
has reasonable ground to believe that the officer is in danger if the person possesses a dangerous 
weapon.”); see also State v. Rollins, 922 A.2d 379, 386 (Del. 2007) (“During a Terry stop, an 
officer may conduct a limited protective search for concealed weapons.  So long as the officer is 
entitled to make a forcible stop, and has reason to believe that the suspect is armed and dangerous, 
he may conduct a weapons search limited in scope to this protective purpose.”) (quotation marks 
and footnotes omitted).   
87 Diggs contends that the search of his person was unlawful but only because his detention was 
unlawful.  As we understand his argument, he does not contend that, even if his detention were 
lawful, the ensuing pat-down search for weapons was nevertheless unlawful. 
 
31 
 
informant,” Diggs’s detention and search were lawful, renders our consideration of 
Diggs’s Section 306 argument unnecessary.  Likewise, because our analysis of the 
reasonableness of Patrolman Shupe’s suspicion is limited to his presumptively 
reliable personal observations and the facts that Corporal Marino communicated to 
him, we need not consider Diggs’s claim that the Superior Court violated the 
“collective knowledge” doctrine as explained in State v. Cooley. 88 
IV. 
 
Diggs next argues that, because the investigating officers failed to collect and 
preserve certain evidence—data from Marino’s and Shupe’s cell phone and the 
store’s surveillance video—the Superior Court was required to draw a “lost/missing 
evidence inference” when it determined the facts relevant to Diggs’s motion.  
Despite his not having requested the court to adopt such an inference, Diggs 
contends that the court’s failure to do so “resulted in the deprivation of [his] due 
process right to a fair suppression hearing.”89  Diggs concedes that this claim is 
subject to plain-error review as we have described it earlier.

Diggs’s argument raises interesting questions regarding how a trial court, 
sitting as the fact-finder in a pretrial evidentiary hearing that is not concerned with 
the defendant’s guilt or innocence, should handle a claim that the State has failed to 
collect and preserve arguably relevant evidence.90  But our standard of review—
plain error—obviates the need to take up those questions. 
 
First of all, the relevance of the text messages and call logs on the officers’ 
personal cell phones is marginal at best—unless, of course, Diggs claims that the 
officers’ testimony that they communicated by cell phone shortly before 
apprehending Diggs was made up out of whole cloth.  But that is not what Diggs 
contends.  Instead, he vaguely alleges that “[t]his evidence was relevant to the 
suppression issues as it related to the circumstances of the tip, and the substance of 
the information exchanged.”91  And what is more, Diggs does not identify a single 
factual finding by the Superior Court that could have been undermined by the cell 
phone records.  Thus, we conclude that, even if the State had an obligation to 
preserve and produce the officers’ cell phone data, Diggs has not shown that its 
failure to produce them violated Diggs’s due process rights as Diggs alleges. 
 
90 We are mindful of this Court’s determination that the prosecution’s obligation to disclose 
exculpatory information can extend to pretrial proceedings and information not directly relevant 
to guilt or innocence when the withholding of that information “deprives the defendant of an 
opportunity to vindicate a possible deprivation of his constitutional rights.”  O’Neil v. State, 691 
A.2d 50, 54 (Del. 1997); see also Pierson v. State, 351 A.2d 860 (Del. 1976). 
91 Opening Br. at 39. 
 
33 
 
 
The same is true for Diggs’s claim that the failure of the police to collect and 
preserve the store surveillance video resulted in a deprivation of Diggs’s due process 
right to a fair suppression hearing.  Diggs claims that the video was subject to 
disclosure under Superior Court Criminal Rule 16 because he requested it, and 
because it was potentially exculpatory and relevant to suppression issues.  But Diggs 
does not show how the video was in “the possession, custody, or control of the 
state,”92 the sine qua non of the State’s discovery obligation. 
 
On this last point, Diggs’s argument runs head-on into the Superior Court’s 
factual findings.  
After the arrest, Officer Shupe asked a person for the footage from a 
camera located in the Market.  Officer Shupe was told by a person 
working at the Market that he did not know how to retrieve the footage.  
At a later date, Officer Shupe went back and tried again to retrieve the 
footage but, once again, was told that no one could retrieve the footage 
and give it to him.93      
 
Nevertheless, Diggs contends that “[t]he police had sufficient authority and 
opportunity to secure the surveillance video, either through a search warrant or 
subpoena.”94  Diggs cites no authority for this proposition, which, in fact, runs 
contrary to our precedent.95  In short, Diggs demonstrated neither that the failure of
