jurisdiction under 28 U.S.C. § 1291, and we affirm. 

In June 2018, police officers located a stolen vehicle parked outside a trailer. 

Officers knew that Richardson, who was a suspect in pending investigations 

involving drug offenses and sex trafficking, resided in the trailer. Officers learned

that the stolen vehicle was associated with a missing female juvenile runaway. 

Two officers knocked on the front door of the trailer while another officer went to 

the back. Richardson opened the front door and the officers smelled marijuana.

Richardson told an officer the juvenile female was in the trailer. 

The officer stationed at the back of the trailer also smelled marijuana. After 

the police knocked on the front door and announced their presence, two males ran 

out the back door past the officer, who identified himself as police and yelled for 

them to stop. The two continued to run, and the officer chased them. Police 

apprehended one and recognized him from a previous encounter in which he had a 

large amount of marijuana and a stolen firearm. 

The three officers reconvened at the trailer. The commanding officer 

testified that he then believed there was probable cause to obtain a search warrant, 

and that the officers decided to first secure the trailer and conduct a protective 

sweep “pending a search warrant application.” They instructed the occupants of 

the trailer to exit, and six people—including Richardson and the juvenile female—

came out. During the sweep, an officer observed a semi-automatic handgun in 
3 

plain view but did not seize it. 

Officers then applied for a search warrant. The affidavit included the 

following: “While performing the security sweep and removing the occupants from 

the residence, officers observed illegal drugs in the form of marijuana in plain view 

throughout the residence along with [a] black semi-automatic pistol. Richardson is 

currently a convicted felon and prohibited from possessing any firearms.” After 

the warrant was issued, officers searched the trailer a second time and seized the 

handgun, suspected marijuana, and other evidence. Richardson was charged with 

being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1). 

Richardson moved to suppress evidence from the trailer, arguing it was 

tainted by the initial warrantless search. The magistrate judge recommended 

denying the motion, explaining that “evidence of the handgun was obtained 

through an independent source.” The district court adopted the magistrate judge’s 

findings and recommendation in full and denied the motion to suppress. 

Richardson entered a conditional guilty plea and now appeals from the district 

court’s denial of his motion to suppress. 

We review de novo the denial of a motion to suppress and review the 

underlying factual findings for clear error. United States v. Perea-Rey, 680 F.3d 

1179, 1183 (9th Cir. 2012). A district court’s “adoption of the findings of a federal 

magistrate judge [is] reviewed for clear error.” Seidel v. Merkle, 146 F.3d 750, 753 
4 

(9th Cir. 1998). Here, the district court correctly determined that the evidence 

from the trailer was admissible under the independent source doctrine. 

A warrantless entry and search of a private residence is presumptively illegal

under the Fourth Amendment. United States v. Iwai, 930 F.3d 1141, 1144 (9th Cir. 

2019). The exclusionary rule “prohibits the introduction of derivative evidence, 

both tangible and testimonial, that is the product of the primary evidence [seized 

during an unlawful search], or that is otherwise acquired as an indirect result of the 

unlawful search.” Murray v. United States, 487 U.S. 533, 536–37 (1988). The 

exclusionary rule does not apply, however, if “the Government learned of the 

evidence from an independent source.” Segura v. United States, 468 U.S. 796, 805 

(1984) (citation and internal quotation marks omitted). When evidence is “initially 

discovered during an illegal search, but is subsequently acquired” through a lawful 

search, the court asks “whether the search pursuant to warrant was in fact a 

genuinely independent source of the information and tangible evidence at issue.” 

Murray, 487 U.S. at 539, 542. In Murray, the Supreme Court explained that the 

subsequent lawful search cannot be an independent source (1) “if the agents’ 

decision to seek the warrant was prompted by what they had seen during the initial 
5 

entry,” or (2) “if information obtained during that entry was presented to the 

Magistrate and affected his decision to issue the warrant.” Id. at 542. 

First, the district court did not clearly err when it found that the officers’ 

observations during the initial entry did not prompt their decision to seek a search 

warrant. The officers testified that they had decided there was probable cause for a 

warrant before the initial search, and that they otherwise “wouldn’t have secured 

the residence pending a search warrant application.” See United States v. Salas, 

879 F.2d 530, 538 (9th Cir. 1989). Richardson’s reliance on the unpublished 

disposition in United States v. Heselius, 671 F. App’x 518 (9th Cir. 2016), is 

misplaced. In Heselius, the panel remanded the case because “the district court 

failed to make any factual findings with respect to whether the unconstitutional 

traffic stop prompted the decision to seek a warrant.” Id. at 519. By contrast, the 

district court here did make the requisite factual finding that the officers’ 

observations during the warrantless entry did not prompt their decision to seek a 

warrant. 

Second, we conclude that after excising the evidence discovered during the 

initial search, the remaining information in the search warrant affidavit was 

sufficient to “provide a neutral magistrate with probable cause to issue a warrant.” 

United States v. Heckenkamp, 482 F.3d 1142, 1149 (9th Cir. 2007) (citation 
6 

omitted).

1

 The warrant application stated, among other things, that the officers 

were familiar with both the residence and Richardson, the officers knew 

Richardson was a suspect in ongoing investigations, the trailer smelled of 

marijuana, there was a stolen vehicle parked outside the residence, a missing 

juvenile had been inside the trailer, and two occupants of the trailer—one of whom 

was known to the officers—fled when the police announced their presence. This 

evidence is more than sufficient to establish probable cause to search the trailer for 

evidence of criminal activity, including possession of marijuana. See United States 

v. Reed, 15 F.3d 928, 933–34 (9th Cir. 1994). Thus, the warranted search provided

an independent source for the evidence, and the district court did not err in denying 

the motion to suppress.

AFFIRMED.

1 We reject Richardson’s argument that the government needed to present 

testimony from the judge who had issued the warrant that he or she would have 

issued it absent the excised information. The standard is as stated in Heckenkamp.
