Philadelphia, PA - Criminal defense lawyer represented defendant with possession of narcotics with intent to distribute and possession of firearms in furtherance of drug trafficking charges.

The charges against Sangster arose from a confidential informant’s tips. In February 2016, City of Pittsburgh Bureau of Police Detective William Churilla met with an informant who claimed Sangster was having large amounts of marijuana and cocaine shipped
to Pittsburgh. The informant claimed Sangster intended to distribute those drugs around
the city, gave Detective Churilla two of Sangster’s cell phone numbers, and identified
Sangster’s vehicle, a black GMC Envoy. He also gave the detective the address Sangster
ran his operation from, a residence belonging to his girlfriend.
The informant met with Detective Churilla again the next month. He claimed Sangster had moved his drug operation to a different address, a house located in Penn Hills, near
Pittsburgh. The informant had been to this house and had seen handguns and an assault
rifle there. Detective Churilla drove past this house on March 26, 2016, and saw Sangster’s
vehicle in the driveway. Approximately two days later, the informant claimed Sangster
had a large quantity of marijuana and cocaine at the same address.
Based on this information, on March 30, 2016, Detective Churilla applied for a warrant to search the Penn Hills home. A Pennsylvania Court of Common Pleas judge issued
the warrant, and the Pittsburgh Police executed it the same day. Officers recovered two
handguns and one assault rifle from Sangster’s home, and a third handgun from his car.
They also found 19 gallon-sized bags of marijuana, 14 bags of crack cocaine and 6 bags of
powder cocaine. In total, police recovered more than nine kilograms of marijuana, 154 3
grams of powder cocaine, and more than 348 grams of crack cocaine. A grand jury indicted
Sangster on charges of possession of 280 grams or more of cocaine, cocaine base (also
known as crack cocaine), and marijuana, and the unlawful possession of firearms in furtherance of a drug trafficking offense.1
Sangster moved to suppress all the drugs and firearms as the fruits of an unlawful
search. He argued the search violated the Fourth Amendment because Detective Churilla’s
affidavit in support of the warrant failed to establish probable cause. The District Court
denied the motion, concluding both that the warrant affidavit established probable cause,
and that the officers acted in good faith by relying on it.
Sangster’s first trial ended with a hung jury. At his second trial, the Court precluded
Sangster’s counsel from arguing in summation that he lawfully possessed his firearms, on
the theory that Sangster had used narcotics, and therefore could not lawfully possess firearms.
Sangster’s counsel was limited to arguing that Sangster had legally purchased or
obtained the firearms, rather than legally possessing them. The jury convicted Sangster on
both counts, and he now appeals.

Sangster raises two issues on appeal: that the District Court erred in denying his
motion to suppress, and that it erred in limiting his counsel’s summation. We address each
in turn.
We review the District Court’s denial of the motion to suppress for clear error as to
findings of fact, and our review is plenary as to conclusions of law.4
But “we conduct only
a deferential review of the initial probable cause determination made by the magistrate,”
which is the same standard the District Court applied here.
The Fourth Amendment protects the right to be free from “unreasonable searches
and seizures.”6 Where a warrant is issued, it must be based “upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the
persons or things to be seized.”7 A magistrate judge may find probable cause when, after
considering the totality of the circumstances, she determines that “there is a fair probability
that contraband or evidence of a crime will be found in a particular place.”8 As opposed
to a “neat set of legal rules,” probable cause is a “fluid concept—turning on the assessment

§ 3231. We have appellate jurisdiction under 28 U.S.C. § 1291.

of probabilities in particular factual contexts.”9 As such, the warrant’s supporting affidavit
must be read in a common sense and nontechnical matter.10
Sangster argues that the District Court erred in denying his motion to suppress because the warrant affidavit did not establish probable cause. He claims that the tips Detective Churilla received from the confidential informant were insufficient on their own to
establish probable cause, and that officers did not sufficiently corroborate them. Considering the totality of the circumstances surrounding the information, we disagree. The Magistrate Judge had a “substantial basis” for concluding that that there was probable cause to
search Sangster’s home and vehicle.11

The warrant affidavit included multiple indicia of probable cause. It specified that
the informant, who was known to officers and had successfully assisted in prior prosecutions, claimed to have “purchased and watched . . . Sangster selling illegal narcotics,” suggesting he or she witnessed drug trafficking firsthand.12
The informant provided detailed
contact information, including Sangster’s two cell phone numbers, Sangster’s addresses,
and the make, model and license plate of Sangster’s vehicle, which Detective Churilla was
able to confirm as being registered to Sangster. Detective Churilla also met the informant
in person three times, allowing him to personally assess the informant’s credibility each
time, and making him accountable to law enforcement should he mislead them.

informant’s tips contained information not known to the general public, including that
Sangster left his weapons lying in plain view in his Penn Hills home. The information was
also recent: Detective Churilla’s last meeting with the informant was at most two days
before he applied for the warrant, and the informant had claimed that Sangster “currently
ha[d] a large quantity of marijuana and cocaine at his” Penn Hills home.14
This provides a
sufficient basis to conclude that contraband would be found there.
Although Sangster argues this information needed further corroboration, Detective
Churilla did confirm that the vehicle the informant claimed was Sangster’s was registered
to him, at the address the informant said he first operated from. After the informant claimed
Sangster had moved to Penn Hills, Detective Churilla drove past this location and saw the
same vehicle in the driveway, corroborating Sangster’s link to this property.15
While Detective Churilla only corroborated innocent details of the informant’s tip, such corroboration can bolster the reliability and veracity of the information.16 Detective Churilla also
14 App. 74.
15 Sangster argues that Detective Churilla’s observation of the vehicle in the driveway did
not corroborate either criminal activity, or that this was Sangster’s residence. But police
were not required to find that Sangster resided at this location in order to establish probable
cause to search it: they merely had to establish a sufficient nexus between the house and
the crime under investigation. Stearn, 597 F.3d at 560. The warrant affidavit had significant direct evidence connecting Sangster’s drug operation to the Penn Hills address. The
informant had claimed to see Sangster use that location to break down and sell drugs, and
had seen his firearms lying around that house. Detective Churilla’s single observation of
Sangster’s vehicle in the driveway merely served to corroborate the informant’s claim that
Sangster had moved his operation to Penn Hills, and that evidence would be found at that

Cir. 2010) (corroboration of color and direction of travel of taxi enhanced tip reliability).7
had a much stronger basis for crediting the informant’s reliability: he had successfully
assisted law enforcement in five other cases, each of which led to guilty pleas. Under these
circumstances, we are satisfied that the District Court correctly concluded that there was
sufficient probable cause to issue the warrant.
But even if we were to conclude that probable cause was lacking, we would still
affirm the denial of the suppression motion based on the good faith exception. The Fourth
Amendment’s exclusionary rule does not require suppression of evidence obtained by an
officer reasonably relying on a search warrant issued by a neutral and detached magistrate,
even if the probable cause determination is later found to be deficient.
While there are
exceptions to this exception, none apply here.18
Sangster argues in passing that the warrant
here qualifies for one of these exceptions: that it was so lacking in indicia of probable
cause as to render an officer’s belief in its existence unreasonable. We disagree. Detective
Churilla’s affidavit described a reliable informant’s description of criminal activity, where
it allegedly took place, and provided a number of methods of corroboration. The warrant
affidavit contained sufficient indicia such that official belief in the existence of probable
cause was not unreasonable.19

17 United States v. Leon, 468 U.S. 897, 923 (1984); Stearn, 597 F.3d at 561.
18 We have previously identified four such exceptions “(1) the magistrate issued the warrant
in reliance on a deliberately or recklessly false affidavit; (2) the magistrate abandoned his
judicial role and failed to perform his neutral and detached function;” (3) where a warrant
is so lacking in indicia of probable cause that official belief in its existence is entirely unreasonable; and (4) where a warrant is “so facially deficient that it failed to particularize
the place to be searched or things to be seized.” Stearn, 597 F.3d at 561 n.19.
19 Id. at 562. 8
We will therefore affirm the District Court’s denial of Sangster’s motion to suppress.
Second, Sangster argues the District Court erred by limiting his counsel’s summation. How this claim arose determines our standard of review, and we address it briefly.
One of the two counts against Sangster was that “during and in relation to [a] . . .
drug trafficking crime” he possessed his firearms “in furtherance of” drug trafficking.20

The mere presence of a firearm is not by itself sufficient to show possession in furtherance
of drug trafficking; the prosecution must demonstrate that the possession “advanced or
helped forward a drug trafficking crime.”21 This Court has adopted a list of nonexclusive
factors to determine whether a firearm possession advances or forwards a drug trafficking
crime, known as the Sparrow factors.
One of the Sparrow factors is “the status of the
possession (legitimate or illegal)” of the firearm.23
Sangster stipulated that all of the firearms the authorities recovered “were all owned and possessed by” him.
20 18 U.S.C. § 924(c)(1)(A)(i).

amended on reh’g in part, 226 F.3d 651 (5th Cir. 2000)). The remaining factors, none of
which are relevant here, are “the type of drug activity that is being conducted, accessibility
of the firearm, the type of the weapon, whether the weapon is stolen, . . . whether the gun
is loaded, proximity to drugs or drug profits, and the time and circumstances under which
the gun is found.” Id.
24 App. 977. 9
At Sangster’s first trial, his counsel argued extensively that he had lawfully possessed his firearms, and the Government agreed. This changed at the second trial. Two
Government witnesses each raised the possibility that Sangster may not have lawfully possessed his firearms. Detective Churilla testified that Sangster’s cell phone had photos and
videos that apparently depicted Sangster using marijuana, and that users of unlawful drugs
are prohibited from possessing firearms.
Master Patrol Officer William Friburger’s testimony also suggested that Sangster used drugs, and therefore that he had not truthfully
completed a background check form for one of his pistols when it asked if he used drugs.
Sangster’s counsel objected to this, and following a sidebar conference, the District Court
precluded either party from introducing evidence of Sangster’s possible drug use.
This evidentiary ruling presented issues for the closing arguments and jury charge.
The District Court had intended to charge the jury by instructing it to consider each of the
Sparrow factors, including whether Sangster lawfully possessed his firearms. In addition
to Detective Churilla’s testimony that Sangster had used marijuana, before the first trial the
District Court precluded the Government from admitting a cell phone video into evidence
that appeared to show Sangster smoking marijuana, concluding it was unduly prejudicial.
The District Court was concerned that it would be misleading to allow Sangster to argue
that he lawfully possessed the firearms, because the excluded evidence could support an
inference that he was a user of narcotics, and therefore that his firearm possession was not
lawful. It proposed the compromise that Sangster could argue that he lawfully purchased
25 See 18 U.S.C. § 922(g)(3) (prohibiting any person “who is an unlawful user of or addicted to any controlled substance” from possessing firearms).10
his firearms, rather than lawfully possessing them at all times. After further discussion
with counsel, the District Court decided to excise the lawful possession Sparrow factor
from its instructions, while permitting Sangster’s counsel to argue that he had lawfully
obtained the firearms.
Our standard of review depends on whether Sangster waived, forfeited, or preserved
the claimed error. To preserve a claim of error for judicial review, an appellant must have
objected to a court’s ruling, requested a certain course of action from the court, or otherwise
brought the alleged error to the court’s attention.26
This Court applies a flexible, commonsense approach to preservation, asking only whether the issue was squarely presented to
the district court.27
Counsel need not use any specific form of words or incantation, the
Court must simply be made aware of counsel’s argument.28

Sangster’s counsel did not object to either the proposed limitation on summation or
the jury charge. He expressly consented to removing the lawful possession Sparrow factor
from the charge, and confirmed that he would not mention lawful possession in closing.
He never suggested that he should be able to argue that Sangster lawfully possessed his
weapons at all times, and his arguments in opposition to the Government addressed
whether Sangster had truthfully completed his background check forms. Although he did
resist the Government’s attempts to argue that Sangster’s prior drug use rendered his

possession unlawful, he never expressed any disagreement with the Court’s restriction on
summation, even initially stating that limiting summation to lawful purchase “was going
to be [his proposed] solution” too.29
Sangster therefore cannot claim to have preserved the
argument he now presses on appeal: that the District Court erred in restricting his summation. We thus agree with the Government that this claim was not preserved.30
Since this argument is not preserved,31 our review may only be for plain error.32
prevail on plain error review, Sangster must show (1) an error, (2) that is plain, and (3) that
affected his substantial rights.33
If Sangster carries this burden, the Court then has discretion to determine whether to correct the error, but only if it seriously affects the fairness,
integrity or public reputation of judicial proceedings.34
Sangster has not demonstrated that any of the plain error requirements have been
met. As to whether the District Court erred in restricting summation, Sangster argues that
29 App. 1312.
30 Sangster points to another place in the record where he claims to have preserved this
argument. After the District Court precluded Officer Friburger from testifying that Sangster was a user of marijuana, the Government sought to prevent his counsel from arguing
in summation that he had lawfully possessed his firearms. At that time, Sangster’s counsel
did not argue that closings should not be restricted, and the District Court did not rule on
the issue, but decided to “ponder it” before closing. App. 1220. Sangster’s counsel did
not “inform the court . . . of the action” he wished the District Court would take, and as
there was no ruling at that time, he could not bring an objection to the Court’s attention.
Fed. R. Crim. P. 51(b). Sangster therefore did not preserve any arguments concerning his
summation there.
31 The Government contends that Sanger waived this argument entirely. If waived, an
appeal on this issue would be precluded. United States v. James, 955 F.3d 336, 344 (3d
Cir. 2020). We need not determine whether Sangster waived or forfeited this argument
however, because even if he merely forfeited it, he cannot prevail on plain error review.

the prohibition on users of narcotics possessing firearms35 could not apply to him, because
the trial evidence was not sufficient to demonstrate that he was a regular user of illegal
As the Government could not establish that his possession was unlawful, he claims
it was error to prevent his counsel from arguing that he lawfully possessed his firearms.
Sangster cannot show any error in limiting his summation under these circumstances. While a total denial of summation would violate his Sixth Amendment rights,37
district courts have “great latitude in controlling the duration and limiting the scope of
closing summations.”
This includes ensuring that summation “does not stray unduly
from the mark, or otherwise impede the fair and orderly conduct of the trial.”39
This is
what the District Court’s solution accomplished. It prevented the parties from using highly
prejudicial and distracting evidence of uncharged criminal conduct that at most would have
addressed only one nonexclusive factor on possession in furtherance of drug trafficking.
Counsel was still permitted to argue that there was “no dispute that Mr. Sangster legally
purchased the firearms” at closing, which he did.
The District Court acted within its wide
latitude in restricting summation here.

36 Id.; United States v. Augustin, 376 F.3d 135, 139 (3d Cir. 2004) (holding that section
922(g)(3) requires proof the defendant was both a regular drug user at the time of the possession, and that the defendant had engaged in regular use over a period of time proximate
to or contemporaneous with the possession of the firearm).
37 Herring v. New York, 422 U.S. 853, 852 (1975); Glebe v. Frost, 574 U.S. 21, 23–24

38 Herring, 422 U.S. at 862.

40 App. 1352. 13
Finally, even if we could characterize the District Court’s solution as error, Sangster
cannot show that it was plain or that it affected his substantial rights. For an error to be
plain, it must be clear or obvious at the time of appellate review.41
There is nothing to
suggest that limiting Sangster’s summation to only permit him to argue that he “lawfully
purchased” rather than “lawfully possessed” his firearms was clear or obvious. Similarly,
he cannot demonstrate that the limitation affected his substantial rights. For an error to
affect substantial rights on plain error review, Sangster “must make a specific showing of
prejudice,” which requires showing that the error affected the trial’s outcome.42
He has not
done so here.
Because the limitation only slightly altered what counsel could argue, and
pertained to only one of a number of nonexclusive factors, there is no reason to believe the
jury would have reached a different outcome had it heard Sangster had lawfully possessed
the firearms. Sangster therefore cannot meet the plain error standard.
41 Olano, 507 U.S. at 734.
42 Id. at 735; United States v. Jackson, 849 F.3d 540, 544 (3d Cir. 2017).
43 Sangster argues that the Court should consider that his first trial ended with a hung jury,
and thus that the limitation on summation prejudiced him here. However, the record suggests that other factors contributed to the first jury being unable to reach a verdict. After
the first jury retired to deliberate, it sent out a note with three questions. The jury requested
clarification on the concept of constructive possession, was concerned with an incorrect
address on a form prepared by law enforcement concerning the search of Sangster’s house,
and it did not understand an abbreviation for text messages used on some of the evidence.
The Court provided further instruction on constructive possession, and although the Government had failed to explain that the address discrepancy was a typographical error, and
had not explained the text messages abbreviation, the Court instructed the jury to resolve
any conflicts in the evidence, without further clarification on either point. The jury was
still unable to reach a verdict. While we cannot conclusively determine why the first jury
was unable to reach a verdict, their questions concerning unrelated evidentiary discrepancies and their inability to reach a verdict on either count rather than just on the firearms
possession count suggests that factors beyond a distinction between “lawful possession”
and “lawful purchase” drove their inability to reach a verdict at the first trial.

Outcome: As we agree with the District Court that probable cause existed to search Sangster’s
residence and because he cannot show that his restricted summation qualifies as plain error, we will affirm his conviction.
