OPINION

¶ 1 In March 2022, defendant, Marquell Eddie Longs, was convicted by a jury of 

(1) first degree murder (720 ILCS 5/9-1(a)(2) (West 2018)) for personally discharging a firearm 

that proximately caused the death of Jennifer Jones, (2) attempted first degree murder (id. §§ 8-

4(a), 9-1(a)(1)) for personally discharging a firearm that proximately caused great bodily harm to 

Tommy Nabors, and (3) unlawful use of a weapon by a felon (id. § 24-1.1(a)). On appeal, 

defendant argues the trial court abused its discretion when it allowed law enforcement officers to 

give lay opinion testimony that identified defendant as the perpetrator of a shooting incident that 

was captured on surveillance video. We affirm.

4th District Appellate

Court, IL
- 2 - 

¶ 3 On December 19, 2018, defendant and two codefendants were charged in a 41-

count indictment for a shooting that caused the death of Jones and injuries to Nabors. Prior to 

defendant’s trial, the codefendants’ cases were severed from defendant’s case. Defendant was 

tried before a jury. The incident involved a shooting that occurred on November 11, 2018, at a 

Citgo gas station in Rockford, Illinois. The gas station was equipped with surveillance cameras 

and was very busy on the night of the incident. We will only recite the relevant facts for 

defendant’s issues on appeal. 

¶ 4 A. Pretrial Proceedings

¶ 5 In December 2019, the State filed a motion in limine, seeking to permit five police 

officers to testify regarding various observations made from the surveillance video. A hearing on 

the State’s motion was held in January 2020. At the hearing, Detective Scott St. Vincent testified 

he worked in the gang unit and had been employed with the Rockford Police Department for 13 

years. St. Vincent reviewed the Citgo surveillance video and identified the individual who fired 

the weapon, who was wearing a dark green hooded sweatshirt and dark-colored pants, as 

defendant. He described having “in-person contact” with defendant “through the years with 

[defendant] at least five times.” Much of his in-person contact with defendant occurred between 

2012 and 2014, including a 2013 investigation involving the shooting death of a friend of 

defendant. St. Vincent did not recall any in-person contact with defendant after 2014. He was 

also able to identify Nabors from the surveillance video due to previous police contacts. Nabors 

was previously charged for his involvement in the shooting investigation from 2013. He stated 

defendant was an “intended target” of the 2013 shooting. 

¶ 6 Following the hearing, the trial court entered a written order granting the State’s 

motion in limine, permitting St. Vincent to narrate the surveillance video and offer an opinion as 
- 3 - 

to the identity of defendant within his knowledge, “subject to the State’s ability to lay a proper 

foundation at trial for [St. Vincent’s] testimony and subject to an appropriate limiting instruction 

on identification issues.” 

¶ 7 In December 2020, defendant filed a motion to suppress Nabors’s identification of 

defendant. However, in January 2021, the trial court announced that Nabors had been shot and 

killed and any motions pertaining to his testimony were “nonoperative.” 

¶ 8 In May 2021, defendant filed a motion seeking to bar St. Vincent’s identification 

of him or, in the alternative, properly instruct the jury about the weight to be given to St. 

Vincent’s testimony. Because defendant had retained new counsel after the January 2020 

hearing, the trial court permitted defendant to reopen proofs on the issue of St. Vincent’s 

identification testimony. In July 2021, the State filed an amended motion in limine, seeking to 

permit Detective D’Evyron Boone to provide identification testimony of defendant from the 

surveillance video.

¶ 9 A hearing was held in August 2021, wherein St. Vincent testified he arrived to 

work the morning after the shooting incident and was asked to review the Citgo surveillance 

video. St. Vincent described the Citgo gas station as being “very crowded,” yet he was able to 

identify defendant and “15 to 20” individuals from the video. Similar to his earlier testimony, St. 

Vincent explained he was familiar with defendant from previous contacts between 2012 to 2014, 

including a shooting investigation in 2013. He recalled his last in-person contact with defendant 

was in 2014. 

¶ 10 Detective Boone testified that, prior to becoming a detective, he had worked in 

the housing authority division from November 2017 through June 2020. Boone watched the 

surveillance video and was able to identify defendant as the individual wearing a “green hoodie 
- 4 - 

or jacket.” Boone stated he immediately recognized defendant from the video. Boone recalled 

interacting with defendant in person “within two weeks” of the shooting during a “non-essential 

stop” at the “West Side Stop” parking lot. During his time with the housing authority, he also 

interacted with defendant “once or twice.” Boone recalled interacting in person with defendant 

“four or five” times. Boone also recalled seeing defendant’s photograph during “daily 

summaries” for active warrants and Crimestoppers.

¶ 11 The trial court entered a written order granting the State’s motion in limine to 

permit St. Vincent and Boone to provide identification testimony of defendant. The court’s order 

also indicated a limiting instruction, pursuant to People v. Thompson, 2016 IL 118667, would be 

provided to the jury. 

¶ 12 B. Jury Trial

¶ 13 The matter proceeded to a jury trial in March 2022. Among the admitted evidence 

was an exhibit that compiled video of the alleged perpetrator of the shooting. 

¶ 14 1. Surveillance Video

¶ 15 The video itself is 9 minutes and 48 seconds long. It is time-stamped as occurring 

on Sunday, November 11, 2018, beginning at 1:51 a.m. It began with a white vehicle arriving at

a side parking lot of the gas station. A black male wearing a green hooded sweatshirt and a 

backward-worn black baseball cap exited the passenger seat of the vehicle. The camera view 

changed throughout the video, following the movements of this individual. 

¶ 16 In front of the gas station were several vehicles near the fuel pumps and several 

individuals outside engaging with occupants of the various vehicles. Inside the gas station was a 

small congregation of people near the cashier counter. The individual entered the gas station, 

walked toward the back area of the gas station, and then exited back to the parking lot. The 
- 5 - 

individual engaged with someone in a parked vehicle and appeared to receive something from a 

backseat passenger, which he then put into his pants. He then proceeded to stand behind the 

white vehicle in which he had arrived and urinated on the ground of the parking lot. The 

individual walked back into the gas station, where there was a larger group of people near the 

cashier counter. He immediately left the gas station, engaged with a few individuals near the fuel 

pumps, took a drink from a bottle given to him, and then walked toward the opposite side of the 

gas station while turning the bill of his hat toward the front of his head. 

¶ 17 He again returned to the front of the gas station and headed back inside, where he 

engaged briefly with a woman in one of the store’s aisles. He again exited the gas station and 

headed toward the parking lot on the opposite side of the building. A camera view from this side 

of the gas station showed roughly 25 vehicles, many running and with their headlights on. The 

individual walked toward a light-colored vehicle on the passenger side and fired several gunshots 

into the vehicle. The shooter immediately walked away. The driver of the vehicle exited before 

the camera angle changed to show the shooter running across the front of the store to the parking 

lot toward the other side from where he initially arrived. The shooter got into the back passengerside seat of a black vehicle, which then left the gas station. 

¶ 18 2. Testimony of Officer Roser

¶ 19 Rockford Police Department officer Corey Roser testified he was on patrol the 

night of the incident and arrived at the gas station. He estimated more than 100 people were at 

the gas station and more than 50 vehicles were in the parking lot. Roser attempted to help both 

Jones and Nabors, who had been shot. 

¶ 20 3. Testimony of Detective Boone
- 6 - 

¶ 21 Boone testified he had worked for the Rockford Police Department for over 13 

years. Following the shooting, he was directed to report to the “District 2” conference room, 

along with other officers, to watch surveillance video from the gas station and identify subjects 

in the video. Boone was able to observe the shooting from the video and identified the shooter as 

wearing a “black hat and green hoodie.” Boone observed the same individual in the gas station 

from multiple angles of the surveillance video. He identified the individual wearing the black hat 

and green hooded sweatshirt as defendant. Boone stated he had no doubt the individual was 

defendant and recalled interacting with defendant “a couple of weeks” prior at the West Side 

Stop. He stated defendant’s appearance from a couple of weeks prior to the shooting had not 

changed. Boone stated he had watched both the raw surveillance video and a compilation video 

showing the shooter’s movements inside and outside the gas station. He also reviewed still 

photos taken from the surveillance video.

¶ 22 On cross-examination, Boone stated he was aware that in 2013 Nabors had been 

previously identified as involved in a murder investigation, the victim of which was someone 

defendant had known. However, he denied this information was relevant to his identification of 

defendant from the surveillance video. On redirect examination, he stated he was never 

personally involved in the 2013 investigation involving Nabors. He also stated defendant’s face 

was not always facing the camera but was visible from certain angles and that no one else in the 

video was wearing clothing similar to what defendant was wearing. 

¶ 23 Following Boone’s testimony, the trial court instructed the jury as follows:

“[B]efore we move on to the next witness in this case, I have an obligation to 

instruct you that you now have before you evidence that a law enforcement 

officer has made an identification of the defendant and other individuals from a 
- 7 - 

video recording. It is for you to determine what weight, if any, should be given to 

that evidence. In determining the weight to be given to this evidence, you should 

not draw any inference from the fact that the witness is a law enforcement 

officer.”

¶ 24 4. Testimony of Detective St. Vincent

¶ 25 St. Vincent also testified he responded to District 2 to review surveillance video. 

St. Vincent described the video as “very clear” and said his objective was to identify as many 

people in the video as he could. He noted the individual who committed the shooting was 

wearing a “green hoodie and black baseball cap.” He recognized the individual as defendant. He 

last had in-person contact with defendant in 2014. He noted five prior contacts with defendant, 

including an investigation in 2013 involving the shooting death of defendant’s friend. Nabors, 

whom St. Vincent also recognized from the video, had been charged in the shooting death of 

defendant’s friend. St. Vincent visited Nabors in the hospital after the shooting. He informed the 

jury that Nabors had died prior to defendant’s trial “from injuries unrelated to the injuries he 

sustained in the November 11, 2018, incident.” St. Vincent described still photographs and a 

compilation video of the shooter’s movement from the night of the incident. He also recalled 

viewing images of defendant on social media a few months prior to the shooting. Following St. 

Vincent’s testimony, the trial court gave the same limiting instruction. We note this limiting 

instruction was given to the jury again as part of the written jury instructions. 

¶ 26 The parties stipulated to defendant having a prior, unspecified, felony conviction. 

The State rested. Defendant did not present any evidence. The jury found defendant guilty of 

(1) the first degree murder of Jones for personally discharging a firearm that proximately caused 
- 8 - 

her death, (2) the attempted first degree murder of Nabors for personally discharging a firearm 

that proximately caused great bodily harm, and (3) unlawful use of a weapon by a felon. 

¶ 27 C. Posttrial Proceedings

¶ 28 Following the jury’s verdict, defendant, through counsel, filed a motion for a new 

trial. Defendant himself also filed pro se motions for a new trial and alleged ineffective 

assistance of counsel. The trial court appointed the public defender for his ineffective-assistance 

claims. Defendant’s appointed counsel then filed an amended motion for a new trial, arguing 

defendant’s trial counsel had failed to challenge Boone’s and St. Vincent’s identification of 

defendant. The amended motion also alleged counsel had failed to call witnesses to rebut the 

detectives’ testimony about their familiarity with him. In October 2022, the court denied 

defendant’s amended motion for a new trial.

¶ 29 Defendant filed a subsequent pro se motion, claiming the trial judge was biased. 

The pro se motion was heard before a different judge and was denied. Defendant’s pro se motion 

to reconsider was also denied.

¶ 30 Defendant’s appointed counsel filed a second amended motion for a new trial in 

February 2023, arguing the trial court erred when allowing detectives to identify defendant from 

the surveillance video and that their identification testimony was not helpful to the jury. The 

court denied defendant’s second amended motion for a new trial.

¶ 31 The matter proceeded to sentencing in May 2023. Defendant was sentenced to 60 

years in prison for first degree murder, 40 years for attempted first degree murder, and 2 years 

for unlawful use of a weapon by a felon. The sentences were ordered to be served consecutively,

for an aggregate 102 years’ imprisonment. Defendant filed a motion to reconsider his sentence, 

which the trial court denied.
- 9 - 

¶ 32 This appeal followed.

¶ 33 II. ANALYSIS

¶ 34 On appeal, defendant argues the trial court abused its discretion when it permitted 

Detectives Boone and St. Vincent to offer lay opinion testimony identifying him as the 

perpetrator of the shooting from the surveillance video. Specifically, defendant contends that the 

video was very high quality, the jury was able to observe him seated at counsel’s table in a welllit courtroom over the three-day trial, and no evidence showed the perpetrator disguised himself 

or that defendant’s appearance had significantly changed. In support of his claim, defendant cites 

Thompson, 2016 IL 118667. 

¶ 35 In Thompson, our supreme court addressed the admissibility of lay opinion 

identification testimony and whether a law enforcement officer may provide such testimony 

under Illinois Rule of Evidence 701 (eff. Jan. 1, 2011). Thompson, 2016 IL 118667, ¶ 40.. The 

Thompson court developed “precautionary procedures,” establishing “that when the State seeks 

to introduce lay opinion identification testimony from a law enforcement officer, the [trial] court 

should afford the defendant an opportunity to examine the officer outside the presence of the 

jury” to “explore” the officer’s familiarity with the defendant, “as well as any bias or prejudice.” 

Id. ¶ 59. Furthermore, the trial court 

“should properly instruct the jury, before the testimony and in the final charge to 

the jury, that it need not give any weight at all to such testimony and also that the 

jury is not to draw any adverse inference from the fact the witness is a law 

enforcement officer.” Id.
- 10 - 

¶ 36 Additionally, the Thompson court adopted a totality-of-the-circumstances 

approach to determine whether a law enforcement officer’s lay opinion identification testimony 

would be helpful to the jury and identified five factors: 

“[(1)] the witness’s general familiarity with the defendant; [(2)] the witnesses’ 

familiarity with the defendant at the time the recording was made or where the 

witness observed the defendant dressed in a manner similar to the individual 

depicted in the recording; [(3)] whether the defendant was disguised in the 

recording or [(4)] changed his/her appearance between the time of the recording 

and trial; and [(5)] the clarity of the recording and extent to which the individual 

is depicted.” Id. ¶ 51. 

¶ 37 The absence of any particular factor does not render the witness’s opinion 

testimony inadmissible. Id. Rather, “a lay witness need only have sufficient contact with the 

defendant, which the jury would not possess, to achieve a level of familiarity that renders the lay 

opinion helpful.” Id. ¶ 42. As such, the extent of a witness’s prior familiarity with the defendant 

is a matter of weight rather than admissibility. Id. ¶ 49. We review the trial court’s decision to 

admit lay opinion identification testimony for an abuse of discretion. Id. 

¶ 38 When addressing the factors from Thompson for determining whether an officer’s 

lay opinion identification testimony would be helpful to the jury, defendant concedes Detectives

Boone and St. Vincent sufficiently established the first factor that both had a general familiarity 

with him that the jury did not possess. 

¶ 39 Regarding the second factor, defendant notes both Boone and St. Vincent had 

testified they observed him shortly before the night of the shooting. Boone stated he had inperson contact approximately two weeks prior to the shooting, and St. Vincent stated he had 
- 11 - 

viewed images of him via social media a few months prior to the shooting. However, neither 

provided details about defendant’s appearance in those prior encounters nor described him as 

being dressed in a similar manner to the individual observed in the surveillance video. The State 

argues both detectives indicated defendant’s appearance had not greatly changed since they last 

observed him prior to the shooting. 

¶ 40 Regarding the third and fourth factors, defendant argues there was no evidence 

from the surveillance video the shooter sought to disguise himself or otherwise conceal his 

identity, nor did defendant alter his appearance between the shooting and his trial. The State 

concedes the suspected shooter from the surveillance video did not disguise himself. However, 

the State notes the suspected shooter appeared to have braids under his hat, whereas defendant’s 

hair length changed in various photographs of defendant that were admitted into evidence. 

Furthermore, the record does not establish defendant’s appearance at trial. The State also 

contends the record suggests defendant wore a mask during some portions of the trial in 

accordance with COVID-19 safety protocols. 

¶ 41 Regarding the fifth factor, defendant argues the high-quality surveillance video, 

combined with a lack of evidence defendant disguised himself or changed his appearance prior to 

trial, provides little basis for concluding Detectives Boone and St. Vincent were in a superior 

position to the jury in identifying him. Furthermore, defendant argues the testimony of law 

enforcement officers, as authority figures, carries additional weight in the eyes of the jury and 

that permitting the detectives to identify defendant on repeated occasions usurped the jury’s 

function to factually conclude for themselves whether the shooter was, in fact, defendant. See, 

e.g., People v. Crump, 319 Ill. App. 3d 538, 544 (2001) (finding a police officer’s testimony that 

he believed the defendant was guilty “was especially prejudicial because, as an authority figure, 
- 12 - 

he was informing the jury that it should believe a portion of the prosecution’s case”). Thus, 

defendant contends the detectives’ testimonies provided minimal probative value that was 

outweighed by the risk of unfair prejudice, thereby amounting to an abuse of discretion by the 

trial court when it permitted their testimonies. The State concedes the jury did not need the 

detectives’ identification testimony to compensate for the surveillance video’s image quality. 

¶ 42 We are unpersuaded by defendant’s arguments. See Insurance Benefit Group, Inc.

v. Guarantee Trust Life Insurance Co., 2017 IL App (1st) 162808, ¶ 44 (“[D]efendant, as the 

appellant, bears the burden of persuasion as to *** claims of error.”). Certainly, the quality of the 

surveillance video, the fact the shooter did not appear to conceal his identity, and the absence of 

record evidence suggesting defendant substantially altered his appearance prior to trial favor 

defendant’s arguments. However, we are reviewing the trial court’s decision to permit Detectives 

Boone and St. Vincent to provide lay opinion identification testimony under the totality of 

circumstances. As the Thompson court noted, if one or more of the factors are present, then there 

is a basis to conclude the witness is in a superior position to the jury to identify the defendant 

from the video or photographic evidence. Thompson, 2016 IL 118667, ¶ 49. 

¶ 43 Here, both detectives provided sufficient testimony to establish a general 

familiarity with defendant. This alone rendered their opinions helpful to the jury. See id. ¶ 50 

(“[T]he witness must only have had contact with the defendant, that the jury would not possess, 

to achieve a level of familiarity that renders the opinion helpful.”). Additionally, Boone had 

made in-person contact with defendant just a couple of weeks prior to the shooting, and St. 

Vincent had seen pictures of defendant a few months prior to the shooting while monitoring his 

social media. Having reviewed the video, we agree the surveillance video is high quality; 

however, the frames do not fluidly transition, resulting in a choppy video. The shooter’s face can 
- 13 - 

be seen on a few occasions but is not readily observable unless the viewers know who they 

should be observing. Therefore, we find under the totality of circumstances the factors do not 

support an abuse of discretion.

¶ 44 Defendant further contends the detectives’ testimonies as law enforcement 

officers were more prejudicial than probative due to the high-quality video, lack of disguise by 

the shooter, and defendant’s unchanged appearance at trial. However, the Thompson court 

established precautionary procedures to “safeguard a defendant’s rights.” Id. ¶ 59. These 

precautionary procedures included (1) allowing a defendant to examine the testifying officer 

outside the presence of the jury to establish the officer’s familiarity with the defendant and

(2) properly instructing the jury that it (a) need not give any weight to the officer’s testimony and 

(b) is not to draw any adverse inference from the fact that the witness is a law enforcement 

officer. Id. These precautionary procedures were sufficiently satisfied in this case when 

defendant was able to cross-examine Boone and St. Vincent at the pretrial hearings. The trial 

court instructed the jurors twice that it was their duty to determine the weight to be given to the 

detectives’ testimonies and to not draw any inferences from the fact they were law enforcement 

officers. That is, the detectives’ testimonies were an issue of weight afforded rather than 

admissibility. Id. ¶ 49. Additionally, unlike in Crump, neither Boone nor St. Vincent ever opined 

their belief as to defendant’s guilt. Rather, both established their familiarity with defendant and 

then made an identification of defendant from the surveillance video based on their individual 

familiarity with him.

¶ 45 A trial court abuses its discretion when its ruling is fanciful, unreasonable, or 

when no reasonable person would adopt its view. People v. Taylor, 2011 IL 110067, ¶ 27. Here, 

the court found the detectives’ testimonies would aid the jury, and based on the Thompson
- 14 - 

factors and precautionary procedures implemented at defendant’s trial, the court acted reasonably

when admitting the testimony of Detectives Boone and St. Vincent. Therefore, we find the court 

did not abuse its discretion when admitting the lay opinion identification testimony of the 

detectives.

¶ 46 III. CONCLUSION

¶ 47 For the reasons stated, we affirm the trial court’s judgment. 

¶ 48 Affirmed.
