ARGUED MAY 22, 2019 — DECIDED AUGUST 15, 2019

Before BAUER, HAMILTON, and SCUDDER, Circuit Judges. 

HAMILTON, Circuit Judge. Defendant-appellant Michael 

Clark was convicted of possessing a mixture containing fentanyl in violation of 21 U.S.C. § 841(a)(1). Clark had been 

found in a hotel room with more than 80 grams of a mixture 

of heroin and fentanyl, a digital scale, and cellophane bags. 

He does not appeal any aspect of his jury trial, but he challenges the denial of his motion for a Franks hearing challenging the issuance of the search warrant for the hotel room. He 
2 No. 18-2604 

also challenges the denial of his motion to suppress without 

an evidentiary hearing. And he challenges two aspects of his 

sentence: the guideline treatment of his conviction for drug 

distribution that occurred in Illinois seven months after his 

Wisconsin arrest and one condition of supervised release. We 

vacate Clark’s conviction and remand for an evidentiary hearing on his Franks challenge. We affirm on the denial of his motion to suppress without a hearing. We also affirm on the 

guideline issue and determine that the supervised release 

challenge was waived. We address in Part I the need for a 

Franks hearing and in Part II the need for an evidentiary hearing on the motion to suppress. We address the sentencing issues in Part III. 

I. The Need for a Franks Hearing

The Fourth Amendment’s strong preference for the use of 

search warrants calls for probable cause determinations by a 

“neutral and detached magistrate” as opposed to “officer[s] 

engaged in the often competitive enterprise of ferreting out 

crime.” Johnson v. United States, 333 U.S. 10, 14 (1948). The application for a warrant “must provide the magistrate with a 

substantial basis for determining the existence of probable 

cause.” Illinois v. Gates, 462 U.S. 213, 239 (1983). 

The ability of the neutral and detached magistrate to determine probable cause depends on the accuracy of the information the police submit. “[A] search warrant is not valid if 

the police obtain it by deliberately or recklessly presenting 

false, material information,” or by omitting material information from the affidavit provided to the issuing judge. 

United States v. McMurtrey, 704 F.3d 502, 508 (7th Cir. 2013), 

citing Franks v. Delaware, 438 U.S. 154, 15556 (1978). To invalidate a warrant on this basis, a defendant at a so-called Franks
No. 18-2604 3

hearing must prove by a preponderance of the evidence either 

falsity or recklessness, as well as materiality. McMurtrey, 704 

F.3d at 509. 

Merely to obtain a Franks hearing, however, a defendant 

does not need to prove the Franks violation. A defendant must 

only make a substantial preliminary showing (1) that the warrant application contained a material falsity or omission that 

would alter the issuing judge’s probable cause determination, 

and (2) that the affiant included the material falsity or omitted 

information intentionally or with a reckless disregard for the 

truth. United States v. Glover, 755 F.3d 811, 820 (7th Cir. 2014); 

see also, e.g., United States v. Hancock, 844 F.3d 702, 708 (7th 

Cir. 2016); United States v. Mullins, 803 F.3d 858, 861–62 (7th 

Cir. 2015); United States v. Robinson, 546 F.3d 884, 887–88 (7th 

Cir. 2008). “Proof by a preponderance of the evidence is not 

required until the Franks hearing itself.” Glover, 755 F.3d at 

820. 

Clark asserted in the district court that the police investigator who applied for the search warrant of the hotel room 

deliberately or recklessly omitted critical information affecting the credibility of the unidentified informant who told the 

officer about drug distribution at the hotel where Clark was 

arrested. The district court denied the motion for an evidentiary hearing on the question. The court agreed that the police 

had provided no information about the informant’s credibility. The court found, however, that the police had provided 

sufficient corroboration for the informant’s tip so that the warrant did not depend on the informant’s credibility. That 

meant the omitted credibility information was not material 

for Franks purposes. We disagree and find that a hearing is 

needed. “[W]e review the denial of a Franks hearing for clear 
4 No. 18-2604 

error, but any legal determinations that factored into the ruling are reviewed de novo.” Glover, 755 F.3d at 815; see also Hancock, 844 F.3d at 70708. 

A. The Warrant Application 

Investigator Todd Maas is a police officer in Superior, Wisconsin. He prepared the warrant application and signed the 

supporting affidavit. Maas said that a confidential informant 

contacted him on October 14, 2015 and told him that earlier 

that day, he had driven someone to a parking lot adjacent to 

the Baywalk Inn in Superior to buy heroin from a black male 

called “Big Mike,” the brother of “Toonchie.” Maas said he 

and another officer then performed their own investigations, 

including surveillance of the parking lot. Maas observed a 

black male leave the hotel and enter and then exit at least five 

cars in the hotel parking lot. He also learned that the guest 

staying in Room 203 was the only hotel guest who both had 

paid in cash and was staying only one night, all behavior that 

Maas said was typical of drug trafficking, based on his training and experience. Maas also said he had spoken to a woman 

(referred to in this case as the “mom on a mission”) who said 

that her daughter was a heroin addict and that she (the 

mother) had followed a man she suspected of drug-dealing to 

Room 203. 

Maas included all of this information in his affidavit, 

which convinced a state trial judge to issue a search warrant 

for Room 203. Maas did not include any damaging information about the credibility of his confidential informant, 

who was the only source of information specifically about 

drug trafficking. The informant was being paid for his services. He also had two pending criminal charges against him, 

fifteen prior convictions, and a history of opiate and cocaine 
No. 18-2604 5

abuse, and he was hoping to receive a reduced sentence in exchange for his cooperation. 

B. Materiality

Where an affidavit is based primarily on tips from an informant, probable cause can be shown based on the totality of 

the circumstances. Gates, 462 U.S. at 238; Glover, 755 F.3d at 

816. In cases based on informants’ tips, we have identified five 

factors of particular relevance: (1) the level of detail the informant provided; (2) the extent to which the informant’s information is based on his or her own first-hand observations; 

(3) the degree to which police have corroborated the informant’s information; (4) the time elapsed between the events reported and the warrant application; (5) and “whether the informant appeared or testified before the magistrate.” Glover, 

755 F.3d at 816, citing United States v. Johnson, 655 F.3d 594, 

600 (7th Cir. 2011). Information omitted from a warrant application is material when its omission affects the probable cause 

determination. Glover, 755 F.3d at 820.

In performing this probable cause inquiry, courts must 

keep in mind that a search warrant for a home, business, or 

even hotel room can authorize highly intrusive and even destructive actions by the police, and that informants, especially 

in drug cases, can be unreliable and motivated by rivalries or 

revenge. United States v. Lopez, 907 F.3d 472, 478 (7th Cir. 

2018), quoting Terry v. Ohio, 392 U.S. 1, 1617 (1968) (“What 

we blandly call ‘Terry stops’ can be highly intrusive.” They are 

“not just ‘a “petty indignity,”’ wrote the Supreme Court, but 

‘a serious intrusion upon the sanctity of a person, which may 

inflict great indignity and arouse strong resentment, and it is 

not to be undertaken lightly’”); United States v. Bell, 585 F.3d 

1045, 1050 (7th Cir. 2009) (“For all we know, [the informant] 
6 No. 18-2604 

could have been a rival drug dealer, an angry customer, or 

had some other beef” with the defendant). 

Our cases do not hold that a Franks hearing is required 

every time some substantial adverse information about an informant’s credibility is omitted from a probable cause affidavit. Hancock, 844 F.3d at 709. We have said generally that 

where a warrant is obtained based on an informant’s tip, “information about the informant’s credibility or potential bias 

is crucial.” Glover, 755 F.3d at 816; see, e.g., United States v. 

Bradford, 905 F.3d 497, 503–04 (7th Cir. 2018). That being said, 

we also have upheld warrants tainted by police omission of 

adverse informant credibility information. Our Franks hearing 

cases show that when police have sufficiently corroborated an 

informant’s tip, the omission of facts pertaining to the informant’s credibility may not be material. 

In United States v. Musgraves, for example, the police omitted from the affidavit important and damaging credibility information about one informant. 831 F.3d 454, 45960 (7th Cir. 

2016). We affirmed the denial of a Franks hearing because a 

second affidavit included information from a second informant without credibility problems who had provided the police 

with specific and timely information about the suspect’s drug 

trafficking to support the warrant. Id. at 46061. 

In United States v. Bradford, we also held that the affidavit’s 

omission of facts damaging to an informant’s credibility did 

not require suppression of evidence seized with a search warrant for drug and weapons trafficking. 905 F.3d at 50305. In 

Bradford, the application failed to disclose that the informant 

had three felony convictions, was on probation, and was being paid for his help. Id. at 502. But his information was fresh, 

specific, and corroborated by his having carried out 
No. 18-2604 7

controlled drug buys from the target and by specific information from another informant without his credibility problems. Id. at 504 

In United States v. Hancock, we affirmed the denial of a 

Franks hearing in similar circumstances. 844 F.3d at 710. An 

informant provided fresh, detailed information about a suspect’s drug sales, but the affidavit for the warrant left out information about the informant’s own criminal history and the 

fact that he was in custody when he provided the information. 

Id. at 70506. We found that the omissions were not material 

because the warrant application included extensive corroboration of the suspect’s drug trafficking and intimidation of 

witnesses. That corroboration came from other informants, a 

search of a cellular telephone showing texts referring to drug 

deals, and from an earlier interview with the suspect himself. 

The quantity and quality of corroborating information meant 

that the omitted adverse credibility information about one informant did not require a Franks hearing. Id. at 70710. 

This case is readily distinguishable. This warrant application did not include any of the substantial adverse information 

Maas had about the informant’s credibility. The government 

does not try to justify Maas’s omissions, but it argues that the 

informant’s credibility was not material to the warrant application because Maas and his colleague investigated and corroborated the informant’s tip sufficiently to provide probable 

cause independent of that tip. We disagree. 

The corroboration in this case was much weaker than in 

the cases where we upheld warrants’ validity in the face of 

credibility omissions. This case is more akin to Glover, where 

the warrant application depended so heavily on the credibility of the informant. Here, the police had no controlled buys. 
8 No. 18-2604 

They never saw money or drugs change hands. Even the informant did not claim to have seen drugs or money change 

hands. If his tip did not pan out, he had plenty of deniability. 

He claimed only that his passenger had met with “Big Mike” 

outside his presence to buy heroin. And the “mom on a mission” had no track record of credibility and provided no specifics to support her suspicions of the man she had followed 

to Room 203. In sum, the foundation for probable cause independent of the credibility of the informant was so meager in 

this case that the credibility of the informant was material for 

Franks purposes.

C. Deliberate or Reckless Omissions?

To obtain a Franks hearing, Clark needed to “offer direct 

evidence of [Maas’s] state of mind or circumstantial evidence 

that [Maas] had a subjective intent to deceive based on the nature of [his] omissions.” Glover, 755 F.3d at 820. In his report 

and recommendation to the district court, we must note, the 

magistrate judge in Clark’s case incorrectly read our decision 

in Glover to “mandate that ... court[s] infer recklessness from 

the fact that an officer omitted known and substantial adverse 

information from a search warrant affidavit....” That is not 

correct. In Glover, we held that “credibility omissions themselves, even in the absence of more direct evidence of the officer’s state of mind, provide sufficient circumstantial evidence to support a reasonable and thus permissible inference 

of reckless disregard for the truth.” Id. (emphasis added). In 

other words, credibility omissions do not require courts to infer recklessness. Such omissions are matters for a trier of fact 

to weigh, just as when a witness testifies incorrectly or falsely 

about one or a few matters, and the trier of fact must weigh 

the rest of the witness’s testimony. 
No. 18-2604 9

In this case, the questions of materiality and the police affiant’s state of mind are intertwined. To the extent that corroboration might have avoided the need for a Franks hearing 

in this case, the reliability of the corroboration all depended, 

from the issuing judge’s point of view, on the same officer 

whose credibility is at issue: Maas omitted all adverse information he had about the credibility of the informant who provided the most specific (but still second-hand) information 

about drug trafficking. As noted, the omission of so much important information permits (but does not require) an inference that the omissions were deliberate or reckless. If the 

showing of probable cause in the warrant application depended on the credibility of the informant, that permissible 

inference should be enough to obtain a Franks hearing. 

The district court’s and government’s rationale for denying a Franks hearing is that Maas’s own observations supply 

probable cause, independent of the informant. We assume 

that if Maas’s own observations are credited, they could lead 

a reasonable judge to find probable cause, though the application would have been much weaker without the informant’s tip to Maas. The problem is that Maas’s credibility can 

legitimately be questioned here based on what could have 

been deliberate or reckless omissions of information about the 

credibility of the informant. 

This is where materiality and intent become intertwined. 

If the omissions were deliberate or reckless, it would not be 

unreasonable to take seriously the prospect that other portions of the same warrant application may have been deliberately or recklessly false. Judges often instruct jurors that if 

they believe a witness has lied intentionally about a material 

matter, they may (but are not required to) discount the 
10 No. 18-2604 

witness’s testimony on other matters. See United States v. 

Weinstein, 452 F.2d 704, 713–14 (2d Cir. 1971) (no positive rule 

of law excludes witness’s testimony entirely based on willful 

falsehood, but such falsification presents issue for jury to consider in weighing rest of testimony), quoting Knowles v. People, 

15 Mich. 408, 412 (1867); Kevin F. O’Malley, Jay E, Grenig, and 

William C. Lee, 1A Fed. Jury Prac. & Instr. §§ 15:0106 (6th ed. 

2019). 

The same point is at the heart of the Supreme Court’s jurisprudence on impeachment evidence in Brady cases. Brady 

v. Maryland, 373 U.S. 83 (1963), and its progeny establish that 

government-suppressed evidence is material “if there is a reasonable probability that, had the evidence been disclosed, the 

result of the proceeding would have been different.’” Kyles v. 

Whitely, 514 U.S. 419, 43334 (1995), quoting United States v. 

Bagley, 473 U.S. 657, 682 (1985). Strong, non-cumulative evidence that undermines the credibility of an important government witness satisfies that definition. Sims v. Hyatte, 914 F.3d 

1078, 1087 (7th Cir. 2019). The reason is simple. Evidence indicating that a witness whose testimony “may well be determinative of guilt or innocence” is unreliable might prompt a 

jury to distrust everything the witness says. Giglio v. United 

States, 405 U.S. 150, 154 (1972). The same logic applies in this 

context. Maas’s potentially intentional or reckless omission 

compromises his credibility, which determines whether probable cause for the warrant existed or not. 

To be clear, we are not saying or finding here that Maas 

was in fact deliberately or recklessly deceptive. The issue on 

appeal is only whether Clark was entitled to a hearing, one 

where Maas’s credibility could be addressed with evidence 

from both sides. The informant was the only source of 
No. 18-2604 11

information (and again, that was only second-hand) who said 

the person in Room 203 was actually dealing drugs. All of the 

other information in the warrant application indicated 

grounds for suspicion, but we can assume that Maas had a 

good reason for including the informant’s more specific information. The complete omission of the available damaging information about the informant’s credibility permits an inference that Maas was not being honest and careful with the issuing court. Whether he in fact was honest and careful about 

the facts is an appropriate subject for the Franks hearing on 

remand.1 

II. The Timing of the Warrant and Search 

Defendant Clark was in Room 203 when police executed 

the warrant. Also in the room were cellophane bags, a digital 

scale, and approximately 82 grams of a mixture of heroin and 

fentanyl. The police photographed the hotel room during 

their search. In a photograph of suspected drugs on a 

nightstand, a digital clock is visible, reading 8:15 p.m. If the 

clock was correct, the search was executed at least 25 minutes 

before the judge issued the warrant.

 1 Maas’s application also did not explain why the informant would 

know heroin if he saw it. See United States v. Peck, 317 F.3d 754, 75657 (7th 

Cir. 2003) (no probable cause for search warrant where affidavit was based 

on informant’s report of seeing drugs in defendant’s house, but according 

to affidavit, informant failed to give details about specific location and 

amount of drugs, or any explanation as to how informant knew that what 

she saw were controlled substances). Nor did Maas provide the kind of 

detail about his own training and experience that is needed to justify reliance upon them. See generally, e.g., United States v. Scott, 901 F.3d 842, 845 

(7th Cir. 2018) (“Details ... are vital when an officer proposes his own 

training and experience as the basis of a warrant”). 
12 No. 18-2604 

The police of course are not permitted to rely on a search 

warrant that has not yet been approved by a judge. The district court denied Clark’s motion to suppress without a hearing. The issue here is whether the photograph of the clock was 

sufficient evidence for Clark to have an evidentiary hearing 

on his motion to suppress. 

A defendant who requests a suppression hearing must 

present “definite, specific, detailed, and nonconjectural facts 

... demonstrat[ing] that there is a disputed material issue of 

fact.” United States v. Rodriguez, 69 F.3d 136, 141 (7th Cir. 1995); 

see United States v. Curlin, 638 F.3d 562, 564 (7th Cir. 2011). 

“Reliance on vague, conclusory allegations is insufficient.” 

United States v. Randle, 966 F.2d 1209, 1212 (7th Cir. 1992). 

In response to Clark’s motion to suppress, the government 

submitted the “metadata” from the digital camera. The 

metadata showed a host of data about each photograph, including the time each was taken. The metadata showed that 

all of the search photographs were taken between 10:36 and 

10:52 p.m., well after the judge issued the search warrant. 

Clark responded in turn not with an affidavit from any witness to the search but with results of Google searches about 

how to edit metadata for photographs. In light of the 

metadata, and in the absence of any specific indications that 

data had been altered, the district court decided that there was 

no need for a hearing and denied Clark’s motion to suppress. 

The situation here is similar to United States v. Woods, 995 

F.2d 713 (7th Cir. 1993).2 In Woods, the police conducted a 

 

2 Another portion of the Woods opinion was abrogated by the Supreme 

Court’s decision in Bailey v. United States, 516 U.S. 137 (1995), as we noted 

in United States v. Monroe, 73 F.3d 129, 133 (7th Cir. 1995). 
No. 18-2604 13

search on February 12th. The problem was that both the warrant and the supporting affidavit bore handwritten dates of 

February 14th, though both were also date-stamped February 

11th. The defendant moved to suppress, arguing that the 

search had been executed two days before the warrant was 

issued. The government responded with an affidavit from a 

prosecutor testifying that the application and warrant were 

both prepared and signed on February 11th and that the February 14th dates were mistakes. Using language associated 

with civil motions for summary judgment—“disputed issues 

of material fact” and “genuine factual dispute”—we affirmed 

the district court’s decision to deny the motion to suppress 

without a hearing. Because the defendant had failed to respond to the government’s explanation, we agreed that he 

had failed to show a genuine factual dispute and a need for 

an evidentiary hearing. Id. at 715–16. 

One might argue that in Woods the government submitted 

an affidavit to explain the discrepancy, while the government 

here submitted letters and copies of documents, without any 

affidavits. Both parties here submitted various documents to 

the district court with this less formal approach. But the burden is on the defendant to support his motion to suppress. 

Missing from this record is an assertion by any witness—defendant Clark or anyone else—to the effect that the search actually occurred at 8:15 p.m. and that the clock was correct. 

Without such an assertion, whether in an affidavit or otherwise (given the less formal procedures being used in the district court), the Google search results about how to alter 

metadata merely invite speculation. The district court did not 

err by denying the motion to suppress, to the extent it was 

based on the photograph of the clock, without a hearing. 
14 No. 18-2604 

III. Sentencing Issues 

A. Relevant Conduct Under the Guidelines 

Clark also challenges two aspects of his sentence. The first 

is a Sentencing Guidelines issue concerning the scope of his 

relevant conduct and criminal history, which are two sides of 

the same coin here. The U.S. Probation Office prepared a PreSentence Report for Clark. Pursuant to U.S.S.G. § 2D1.1(a)(5) 

and (c)(8) of the 2016 Sentencing Guidelines Manual, the PSR 

calculated Clark’s base offense level as 24 because he possessed between 40 and 160 grams of a substance containing 

fentanyl. No other adjustments applied, so his total offense 

level remained 24. The PSR also determined that Clark had 11 

criminal history points and was in criminal history category 

V. Three of those 11 points were from a 2017 federal conviction for drug distribution stemming from events that occurred 

in Illinois after Clark was arrested in this Wisconsin federal 

case. Clark also received three points for a prior felony drug 

conviction in Minnesota. Because of the Minnesota conviction, Clark faced a 120-month mandatory minimum pursuant 

to 21 U.S.C. § 851. (If not for the enhancement, Clark would 

have had an advisory guideline range of 92 to 115 months.) 

Both the government and Clark argued for the 120-month 

mandatory minimum sentence. The district court adopted the 

facts of the PSR and determined that the PSR had calculated 

correctly Clark’s offense level, criminal history, and guideline 

range. The court sentenced Clark to 120 months in prison to 

be served consecutively to the 71-month sentence he had received in the Illinois case. 

On appeal, Clark argues that his later drug offense in the 

Illinois conviction should be treated under the Sentencing 
No. 18-2604 15

Guidelines as “relevant conduct” for this case rather than as 

part of his criminal history. That means, he contends, his 120-

month sentence in this case should run concurrently with the 

71-month sentence he received in Illinois. Clark did not raise 

this argument in the district court. At sentencing, the government asked that Clark’s sentence run consecutively to his Illinois sentence. Clark did not object. He requested only that 

this sentence run concurrently with any state sentence. The 

government argues that Clark therefore waived this issue. 

Waiver is the intentional relinquishment of a known right, 

whereas forfeiture occurs when a defendant “negligently fails 

to assert a right in a timely fashion.” United States v. Brodie, 

507 F.3d 527, 530 (7th Cir. 2007); see United States v. Olano, 507 

U.S. 725, 733 (1993). Concurrent sentences would reduce significantly the time Clark spends in prison. There is no reason 

for us to draw the inference here that Clark intentionally 

waived this argument. “Waiver principles should be construed liberally in favor of the defendant,” and we are hesitant, without more, to construe a defendant’s failure to object 

to a PSR as an intentional relinquishment of a known right. 

United States v. Jaimes-Jaimes, 406 F.3d 845, 84849 (7th Cir. 

2005). This is especially the case where, as here, the defendant 

had no strategic reason to forgo this sentencing argument. See 

United States v. Jenkins, 772 F.3d 1092, 1096 (7th Cir. 2014). 

Plain-error review, however, does not win relief for Clark 

on this issue. Plain-error review allows reversal where: (1) 

there was an error; (2) the error was plain; (3) the error affected the substantial rights of the defendant; and (4) the error 

seriously impacted the fairness, integrity, or public reputation 

of the proceedings. Olano, 507 U.S. at 73238; United States v. 

Duran, 407 F.3d 828, 834 (7th Cir. 2005). Here, we need not 
16 No. 18-2604 

address the third and fourth elements. If any error occurred 

at all, it was not “plain.” 

Under § 5G1.3(b) of the Guidelines, where a defendant has 

an undischarged term of imprisonment, and where the conduct that led to the undischarged sentence 

is relevant conduct to the instant offense of conviction under the provisions of subsections 

(a)(1), (a)(2), or (a)(3) of § 1B1.3 (Relevant Conduct), the sentence for the instant offense shall 

be imposed as follows: 

(1) The court shall adjust the sentence for 

any period of imprisonment already 

served on the undischarged term of imprisonment if the court determines that 

such period of imprisonment will not be 

credited to the federal sentence by the 

Bureau of Prisons; and 

(2) the sentence for the instant offense 

shall be imposed to run concurrently to 

the remainder of the undischarged term 

of imprisonment. 

Section 5G1.3(d) further advises that “in any other case involving an undischarged term of imprisonment, the sentence 

for the instant offense may be imposed to run concurrently, 

partially concurrently, or consecutively to the prior undischarged term of imprisonment to achieve a reasonable punishment for the instant offense.” So if Clark’s Illinois offense 

was relevant conduct here, the Guidelines would recommend 

concurrent sentences. If his Illinois offense was not relevant 

conduct here, the choice of consecutive or concurrent 
No. 18-2604 17

sentences is left to the discretion of the sentencing judge, and 

there is no reason to find an abuse of discretion here. 

As for the scope of relevant conduct, § 1B1.3(a)(1)(A) provides that “relevant conduct” is based on “all acts and omissions committed, aided, abetted, counseled, commanded, induced, procured, or willfully caused by the defendant.” “Section 1B1.3(a)(2) applies to grouped offenses and includes ‘all 

acts and omissions described in subdivisions 1(A) and 1(B) 

that were part of the same course of conduct or common 

scheme or plan as the offense of conviction.’” United States v. 

Schrode, 839 F.3d 545, 551 (7th Cir. 2016), quoting U.S.S.G. 

§ 1B1.3(a)(2). 

“In assessing whether offenses are part of the same course 

of conduct, we focus on whether the government has demonstrated a significant similarity, regularity, and temporal proximity.” United States v. Baines, 777 F.3d 959, 963 (7th Cir. 2015) 

(internal citations omitted). In considering whether an offense 

is relevant within the meaning of § 1B1.3, our court has emphasized several factors that should guide courts’ analysis. 

“Sufficient factual overlap exists where the past and present 

offenses involve the same victims, stem from the same underlying conduct, or are in fact similar offenses.” United States v. 

Orozco-Sanchez, 814 F.3d 844, 850 (7th Cir. 2016); see also 

United States v. Sumner, 325 F.3d 884, 889 (7th Cir. 2003) (in 

deciding relevant conduct in drug cases, courts look for “a 

strong relationship between the uncharged conduct and the 

convicted offense, focusing on whether the government has 

demonstrated a significant similarity, regularity, and temporal proximity”), quoting United States v. Acosta, 85 F.3d 275, 

279 (7th Cir. 1996). The relevant conduct issue is similar to the 

issue in calculating criminal history under U.S.S.G. § 4A1.2 
18 No. 18-2604 

(defining “prior sentence”), where two similar prior convictions separated by an intervening arrest are counted separately. E.g., United States v. Morgan, 354 F.3d 621, 623 (7th Cir. 

2003); United States v. Bradley, 218 F.3d 670, 673 (7th Cir. 2000). 

The district court did not plainly err in not treating Clark’s 

later offense in Illinois as relevant conduct for his Wisconsin 

conviction. To support his argument, Clark points to facts set 

forth in his Wisconsin PSR. The PSR explained that Clark traveled to Chicago to obtain the drugs that he would then sell in 

Wisconsin. This fact, Clark asserts, establishes that his drug 

activities in both states were part of the same course of conduct, his fentanyl-trafficking enterprise. 

Under our precedents, this argument faces obvious “temporal proximity” and “similarity” problems. First, Clark was 

arrested in Wisconsin seven months before he was arrested 

for selling a fentanyl mixture in Illinois. Further, the offenses 

were dissimilar. In Wisconsin, Clark possessed more than 80 

grams of fentanyl, most of which was packaged in retail packages of 0.5 grams. In Illinois, by contrast, he was arrested for 

selling a confidential informant more than 65.2 grams of fentanyl. And even if the offenses had been more similar, “the 

fact that a defendant commits a certain type of offense on multiple occasions does not inevitably mean that each separate 

offense is part of the same course of conduct.” Schrode, 839 

F.3d at 552. There is not enough here to have required the district court to have found such strong connections between 

these two drug offenses, especially without an objection by 

the defense to that effect. The offenses involved different buyers, in different cities, in different types of quantities, months 

apart, and with an intervening arrest for the Wisconsin offense.

“An error is ‘plain’ if the law at the time of appellate review shows clearly that it was an error.” United States v. 

Pierson, 925 F.3d 913, 919 (7th Cir. 2019), citing Henderson v. 

United States, 568 U.S. 266, 279 (2013). Clark cannot establish 

with precedent or otherwise that the district court should 

have acted sua sponte to treat his Illinois offense as conduct 

relevant to his Wisconsin charge. Even if there might have 

been an error, it was not plain error to run Clark’s two federal 

sentences consecutively. 

B. Supervised Release Condition 

Finally, the district court imposed a supervised release 

condition that Clark “Not meet, communicate or spend time 

with any persons known by defendant to be a member of or 

affiliate of any known street gang.” On appeal, Clark argues 

that the term “affiliate” is unconstitutionally vague. He did 

not object to this condition at sentencing. 

In at least scores of appeals over the past five years, in the 

wake of United States v. Siegel, 753 F.3d 705 (7th Cir. 2014), 

United States v. Thompson, 777 F.3d 368 (7th Cir. 2015), and 

United States v. Kappes, 782 F.3d 828 (7th Cir. 2015), this court 

has wrestled with how best to handle appellate challenges to 

supervised release conditions that were not raised in the district court. Our recent opinion in United States v. Flores, 929 

F.3d 443 (7th Cir. 2019), should bring some order to our 

caselaw in this niche of waiver law, particularly since it was 

circulated to the entire court under Circuit Rule 40(e), and no 

judge voted to hear the case en banc. Special considerations 

apply to our handling of supervised release conditions both 

because they are usually the least salient concern at the time 

of sentencing and, more important, because a defendant may 

challenge them in the district court at any time. See Flores, 929 
20 No. 18-2604 

F.3d at 451, citing 18 U.S.C. § 3583(e)(2); see also United States 

v. Lewis, 823 F.3d 1075, 1083 (7th Cir. 2016) (defendant waived 

challenge to supervised release condition: “sentencing in the 

district court is the main event”). 

This case meets the standards of waiver set forth in Flores: 

Clark had prior notice of the proposed conditions, including 

the “affiliate” condition. He had a meaningful opportunity to 

object, and his lawyer told the judge that the proposed conditions were acceptable. Clark even raised other objections to 

the PSR prior to sentencing but did not challenge this condition, which signals an intentional decision not to object. See 

Flores, 929 F.3d at 449. 

We REVERSE the district court’s denial of Clark’s motion 

for a Franks hearing without an evidentiary hearing. We 

VACATE the district court’s judgment and REMAND for a 

Franks hearing and appropriate action based on the outcome 

of that hearing, either granting Clark’s motion to suppress or, 

if his motion is denied, reinstating the convictions and sentence. If the judgment is reinstated, the denial of Clark’s motion to suppress and the district court’s sentence are 

AFFIRMED. 
No. 18-2604 21 

SCUDDER, Circuit Judge, dissenting in part. The panel opinion is well done, and I join all parts of it except the conclusion 

that the district court should have granted Michael Clark’s 

motion for a Franks hearing. In my view, Investigator Todd 

Maas’s affidavit supporting the search warrant, while omitting facts damaging to the confidential informant’s credibility—facts that unquestionably should have been included— 

adequately corroborated the information supplied by the informant. The district judge reached this precise conclusion, 

and under the deferential standard that guides our review on 

appeal, we should affirm. There was no clear error here. 

I 

The majority’s opinion correctly articulates the standard 

for obtaining a Franks hearing: a defendant must make a substantial preliminary showing that an officer intentionally or 

recklessly omitted information from a search warrant affidavit and the omissions were material to the probable cause determination. See United States v. Glover, 755 F.3d 811, 820 (7th 

Cir. 2014). The majority also rightly observes that the omission of adverse information about an informant’s credibility 

does not automatically warrant a hearing. See United States v. 

Hancock, 844 F.3d 702, 709 (7th Cir. 2016). Instead the proper 

question is whether the affidavit would have established 

probable cause if the omitted information had been included. 

See id. at 708. To make this determination, we consider the 

totality of the circumstances, including “the extent to which 

the police have corroborated the informant’s statements.” 

United States v. Sutton, 742 F.3d 770, 773 (7th Cir. 2014). 

All agree that Investigator Maas failed to disclose critical 

facts about the informant’s background. In my judgment, 

though, the warrant application had sufficient corroboration 
22 No. 18-2604 

to overcome this omission and establish the requisite probable cause to search hotel room 203 at the Baywalk Inn. Maas 

took care to include three key pieces of corroborating evidence in his affidavit: 

 In response to the informant’s tip about possible drug 

dealing at the Baywalk Inn, Investigator Maas surveilled the hotel and observed a black male exit the 

hotel and quickly enter and exit at least five cars. 

Drawing on his experience as a narcotics investigator, 

Maas characterized this conduct as “textbook behavior to dealing narcotics.” 

 Maas discovered that only two of the hotel’s 25 rooms 

had been rented with cash, with only one of the two—

room 203—being rented for one night, which Maas 

explained was consistent with drug trafficking because “drug dealers usually pay in cash and only stay 

one or two nights so to throw off police.” 

 Maas also reported that, upon arriving at the hotel, he 

had a conversation with a woman he identified by 

name in the warrant application, who said her 20-

year-old daughter was addicted to heroin. The 

woman added that, before the officer arrived, she was 

“also watching the black male who [was] suspected to 

be dealing” and she followed him to room 203. 

The majority’s analysis discounts this information, reasoning that Investigator Maas’s omission of material facts about 

the informant’s background compromised his credibility on 

all other portions of the warrant application. Put another way, 

if Maas omitted critical information about the informant’s reliability, nothing else he included in his affidavit deserved to 
No. 18-2604 23

be credited as part of the probable cause analysis. But our case 

law does not require such broad discounting and distrust. See, 

e.g., United States v. Bradford, 905 F.3d 497, 503–05. The district 

court was not required to view as worthless the entirety of the 

corroborating information provided by Maas. 

To be sure, a court faced with a reckless or intentional 

omission of material information may consider whether (and 

to what extent) the omission bears on the officer’s credibility 

as part of its probable cause analysis. But I cannot say that the 

district court clearly erred, in light of other corroborating evidence, by choosing to credit Maas’s affidavit despite his 

omission. So I would affirm the court’s denial of Clark’s motion for a Franks hearing. 

* * * 

A final observation seems worthwhile. When this case entered federal court, a magistrate judge reviewed the statecourt warrant application and noted that it, like many others 

prepared by law enforcement officers in Wisconsin, omitted 

information about the confidential informant’s criminal history. The panel’s opinion, aligned with our precedent, reinforces that this information is essential to a proper probable 

cause analysis under the Fourth Amendment. See, e.g., United 

States v. Musgraves, 831 F.3d 454, 460 (7th Cir. 2016). Given the 

frequency with which search warrants sought and executed 

at the state level result in federal prosecutions, Wisconsin law 

enforcement would do well to revisit its warrant application 

practices. Omitting information about an informant’s credibility creates real yet avoidable peril. Today’s decision proves 

the point.
