registration permit displayed in its rear window. Officer Freeman could read the
number on the permanent license plate, but he could not discern the number on the
temporary permit. Officer Freeman ran the number on the permanent license plate
through his computer database, which indicated that the license plate was not
registered to any vehicle.
Officer Freeman turned on his emergency lights and pulled over Deluca into
the parking lot of a motel. Officer Freeman asked for Deluca’s driver’s license and
registration. Deluca replied that he had a valid license, registration, and proof of
insurance, but did not have them with him in the car. Officer Freeman then asked
Deluca for his name and date of birth so he could check on the status of his driver’s
license. Deluca identified himself as “Jack McAlley,” gave a fictious date of birth,
and said that he was nervous about being pulled over. Officer Freeman returned to
his patrol car and radioed for Canine Officer Eric Norris to come to his location.
Officer Freeman then used his patrol car computer to query the name and date of
birth given by the Deluca but was unable to obtain any information. Freeman radioed
police dispatch to try their databases, and they were also unsuccessful.
Officer Norris arrived after a few minutes and deployed a drug dog named
Maverick to conduct a sniff around the vehicle. Maverick alerted on the driver’s side
of the car. The officers removed Deluca from his Cadillac, searched him, and moved
him to a patrol car. The officers then searched the Cadillac and discovered a gun and
Deluca’s driver’s license. A database check of Deluca’s real name revealed an
outstanding warrant for his arrest in Pennsylvania and that his license was suspended.

Deluca told the officers that he was a felon,2 and Deluca later informed them that he
had been using marijuana earlier that day and was still wearing the same clothes.
Officer Norris later theorized that Deluca’s clothes triggered Maverick to alert.
The government charged Deluca with one count of felon in possession of a
firearm in violation of 18 U.S.C. § 922(g)(1). Deluca filed a motion to suppress the
evidence obtained in the traffic stop, raising a number of issues including that Officer
Freeman lacked reasonable suspicion in order to conduct the traffic stop and lacked
probable cause to conduct the search of the vehicle that uncovered the gun. To
support probable cause for the search, the government relied on Maverick’s alert on
the vehicle. At the evidentiary hearing on the motion, Officer Norris testified that
Maverick was trained to alert for only four substances: marijuana, cocaine, heroin,
and methamphetamine. On cross-examination however, Officer Norris admitted that
he was unsure what part of the marijuana plant that Maverick was able to identify,
meaning that he did not know whether the dog could distinguish hemp—a legal
substance in Wyoming—from marijuana.
The district court denied the motion to suppress, finding that Officer Freeman
had both reasonable suspicion to justify the stop and probable cause to justify the

made a factual finding on whether Maverick would alert on hemp in determining that
probable cause for the search existed. Deluca pled guilty following the denial of his
motion to suppress. He was sentenced to 120 months’ imprisonment plus three years
of supervised release. Deluca now appeals to this court, arguing that the district
court erred in finding that Officer Freeman had reasonable suspicion for the stop and
in failing to make an essential factual finding in determining that the officers had
probable cause to search the vehicle.
II. DISCUSSION
A. Officer Freeman’s traffic stop was justified by reasonable suspicion.
Deluca contends that the district court erred in denying his motion to suppress
because Officer Freeman lacked reasonable suspicion to stop him. The government
argues that Officer Freeman had reasonable suspicion that Deluca’s car was unregistered
when Freeman queried the permanent license plate in his database and it returned as
“unregistered.”3 While this theory of reasonable suspicion is raised for the first time on
appeal, we are free to exercise our discretion to affirm the denial of a suppression order
on alternative grounds “when the record below is sufficient to permit [this Court] to
3 The government also argues that reasonable suspicion was established by the simultaneous display of an unregistered permanent license plate and a temporary permit, which it argued is unlawful under either Pennsylvania or Wyoming state law or in any event supports an officer’s objectively reasonable mistake in believing it was unlawful. The district court below found that Officer Freeman had reasonable suspicion due to the simultaneous display of the plates violating Pennsylvania law. We need not reach this theory as we find the stop to be justified based upon reasonable suspicion that the vehicle was unregistered. 5 Appellate Case: 20-8075 Document: 010110726371 Date Filed: 08/18/2022 Page: 6
conclude, as a matter of law, that [d]efendant’s Fourth Amendment rights were not
violated.” United States v. Nelson, 868 F.3d 885, 891 (10th Cir. 2017) (quoting United
States v. Mora, 293 F.3d 1213, 1216 (10th Cir. 2002)). Here the record is sufficient to
support the conclusion that Officer Freeman had reasonable suspicion that Deluca’s
vehicle was unregistered in order to conduct the traffic stop.
A routine traffic stop is a seizure within the meaning of the Fourth Amendment
and must be reasonable. Delaware v. Prouse, 440 U.S. 648, 653 (1979). Because a
routine traffic stop is more akin to an investigative detention than a custodial arrest, a
traffic stop is reasonable if (1) “the officer’s action was justified at its inception,” and (2)
the officer’s action “was reasonably related in scope to the circumstances which justified
the interference in the first place.” United States v. Botero-Ospina, 71 F.3d 783, 786
(10th Cir. 1995) (en banc). A routine stop is justified when reasonable articulable
suspicion exists to believe a traffic violation has occurred. See id. at 787. In evaluating
reasonable suspicion, we must look at the totality of the circumstances to see whether a
reasonable officer in Officer Freeman’s position would have had a “particularized and
objective basis” for suspecting legal wrongdoing. United States v. Arvizu, 534 U.S. 266,
273 (2002). Officer Freeman’s subjective beliefs as to the basis for the stop are
irrelevant.4 Whren v. United States, 517 U.S. 806, 813 (1996). In reviewing the denial
of a motion to suppress, this court reviews a district court’s factual determinations for
4 Deluca makes a host of arguments based on the subject beliefs of Officer Freeman. These are irrelevant under Whren. 6 Appellate Case: 20-8075 Document: 010110726371 Date Filed: 08/18/2022 Page: 7
clear error and the ultimate determinations of reasonableness under the Fourth
Amendment de novo. United States v. Patten, 183 F.3d 1190, 1193 (10th Cir. 1999).
The government attempts to justify the stop by arguing that Officer Freeman had
reasonable suspicion that Deluca’s vehicle was unregistered because Officer Freeman
queried the permanent license plate on the car, and it came up “unregistered.” We have
“regularly upheld traffic stops based on information that the defendant’s vehicle’s
registration failed to appear in a law enforcement database.” United States v. Esquivel-
Rios, 725 F.3d 1231, 1235 (10th Cir. 2013); see also United States v. Stephens, 350 F.3d
778, 780 (8th Cir. 2003) (“In this case, the information obtained from a computer check
. . . provided the police with reasonable suspicion to stop the vehicle and investigate
whether the vehicle was properly registered and whether Stephens was operating the
vehicle with a valid license.”). Deluca argues that his case is distinct because Officer
Freeman also spotted a temporary permit displayed in the back window of the car.
However, even the unusual display of a temporary permit where the officer struggles to
read the number alone can give rise to reasonable suspicion for an officer to stop a
vehicle. See United States v. McSwain, 29 F.3d 558, 561 (10th Cir. 1994) (noting that
the defendant had conceded that there was reasonable suspicion for a stop where the
officer could not read the temporary permit). Reasonable suspicion does not require an
officer to rule out the possibility of innocent conduct—here, the possibility that perhaps
the temporary license plate was properly registered. United States v. Arvizu, 534 U.S.
266, 277–78 (2002) (citing Illinois v. Wardlow, 528 U.S. 119, 125 (2000)) (“A
determination that reasonable suspicion exists . . . need not rule out the possibility of
7 Appellate Case: 20-8075 Document: 010110726371 Date Filed: 08/18/2022 Page: 8
innocent conduct” as long as the totality of the circumstances suffices to form a
“particularized and objective basis” for the stop.). As there was a particularized basis to
believe that the car was unregistered based on the database result, and Freeman’s inability
to read the permit, we conclude that the stop was justified in its inception by reasonable
suspicion.
Deluca contends next that even if the stop was justified in its inception the scope
of the stop performed by Officer Freeman exceeded what the circumstances permitted.
An “unregistered” result in a database search for the license plate number displayed on a
car gives reasonable suspicion only “to stop the vehicle and investigate whether the car
was properly registered.” Stephens, 350 F.3d at 780. Deluca suggests that all Officer
Freeman was permitted to do after the stop was to get a closer look at the temporary
permit and confirm that it was valid without asking any questions. According to Deluca,
Officer Freeman’s request for a driver’s license and additional questions were not
permitted.
In support of this, Deluca cites McSwain, 29 F.3d at 561, where we held that an
officer who struggled to read a temporary license plate exceeded the permissible scope of
a traffic stop by questioning and requesting the suspect’s driver’s license. McSwain
however rests on the fact that reasonable suspicion dissipated after the officer read and
confirmed the validity of the temporary permit prior to questioning the driver and
requesting a license. Id. We noted that where the reasonable suspicion has not
dissipated, the officer may still proceed with a brief questioning and request for a license.
Id. Here, unlike in McSwain, reasonable suspicion did not dissipate upon confirming the
8 Appellate Case: 20-8075 Document: 010110726371 Date Filed: 08/18/2022 Page: 9
validity of the temporary permit. While Officer Freeman was able to better see the
temporary permit and confirm its validity as he approached the car, he still had
reasonable suspicion that the car was unregistered based on the unregistered permanent
plate on the vehicle and the unusual simultaneous display of the plates. It was therefore
reasonable for him to proceed to ask Deluca for his license and registration. Thus, the
scope of the stop was not unreasonable given the basis for the stop.
We therefore find that Officer Freeman had reasonable suspicion to stop Deluca,
and his stop was justified both in its inception and scope.
B. The district court did not violate Rule 12 of the Federal Rules of Criminal Procedure when it declined to resolve a factual question as to whether the drug dog was trained to alert on hemp.
In his motion to suppress in the district court, Deluca contended that the officers
lacked probable cause to search Deluca’s vehicle. The government’s argument for
probable cause was that Maverick, the drug dog, had alerted on the vehicle. Deluca
responded on the basis of information and belief that Maverick was trained to alert on
hemp—a legal substance in Wyoming—in addition to controlled substances, and if so the
alert of a dog trained to alert on legal substances, as well as illegal ones could not provide
probable cause for a search of a vehicle. On appeal, Deluca argues that the district court
failed to make a factual finding on the record, in violation of Rule 12 of the Federal Rules
of Criminal Procedure, as to whether Maverick was trained to alert on legal hemp.
Deluca seeks reversal of the district court’s probable cause determination and remand for
the district court to resolve this factual issue.
9 Appellate Case: 20-8075 Document: 010110726371 Date Filed: 08/18/2022 Page: 10
Fact-finding is a basic responsibility of the of district courts. United States v.
Ramstad, 219 F.3d 1263, 1265 (10th Cir. 2000). Rule 12(d) of the Federal Rules of
Criminal Procedure states that “where factual issues are involved in determining a
motion, the court shall state its essential findings on the record.” However, “[a] district
court need not place all of its findings on the record provided the essential bases of its
decision are apparent.” Ramstad, 219 F.3d at 1265.
First, we must determine whether the district court actually failed to make the
factual finding at issue. The government contends that the district court did find that
Maverick was not trained to alert on hemp when it stated in its order: “Maverick alerted
to the presence of one of the four controlled substances which he is trained to identify
(marijuana, heroin, methamphetamine and cocaine).” Aple. Br. at 25 (citing ROA Vol I.
at 94). But the court added this in a footnote to that statement:
Officer Norris testified that Maverick is not trained or certified to alert on hemp. On cross-examination, Officer Norris recognized that hemp is closely- related to marijuana with a minute amount of THC. He could not identify the specific component(s) of marijuana that Maverick recognizes. However, the possibility of false-positives regarding hemp is not dispositive in this case. It is not disputed that Defendant said he had smoked marijuana that day in the same clothes, and Defendant does not contend that hemp was in the car.
ROA Vol. I 94 n. 4 (emphasis added). Based on this statement, we conclude that the
district court declined to resolve this factual issue as it merely found the question
regarding hemp was not dispositive as to whether the officers had probable cause.
The question under Rule 12 then becomes whether this factual finding was
“essential” to the outcome of the probable cause question. We find that it is not essential
because probable cause existed even if Maverick was trained to alert on hemp in addition
10 Appellate Case: 20-8075 Document: 010110726371 Date Filed: 08/18/2022 Page: 11
to the other controlled substances. “Probable cause exists where ‘the facts and
circumstances within their (the officers’) knowledge and of which they had reasonably
trustworthy information (are) sufficient in themselves to warrant a man of reasonable
caution in the belief that’ an offense has been or is being committed.” Brinegar v. United
States, 338 U.S. 160, 175–76 (1949). Probable cause “requires only a probability or
substantial chance of criminal activity, not an actual showing of such activity.” Illinois v.
Gates, 462 U.S. 213, 231 n. 13 (1983).
It is undisputed that Maverick was trained to alert on marijuana, heroin,
methamphetamine, and cocaine. If hemp was added to this list of four controlled
substances, Maverick’s alert on a car would still give rise to a high probability that a
controlled substance is in the car as four of the five substances that Maverick could detect
are illegal.5 Thus, we find that the officers had probable cause to search the car
regardless of whether Maverick was trained to alert on legal hemp. This was therefore
not an essential factual finding, and so the district court did not need to resolve it on the
record under Rule 12. We affirm the denial of the motion to suppress.
5 Deluca presented no evidence and no argument about how common it is that hemp is found in a vehicle in the absence of other controlled substances. 11 Appellate Case: 20-8075 Document: 010110726371 Date Filed: 08/18/2022 Page: 12
CONCLUSION
For the above reasons, we AFFIRM the district court’s denial of the motion to
suppress.
