The Honorable Lee H. Rosenthal, United States District Judge for the

judgment on his false arrest/false imprisonment and malicious prosecution claims
in favor of Appellee-Defendants Detective Santos Luevano and the City of
Bakersfield. We have appellate jurisdiction under 28 U.S.C. § 1291, and we
affirm.
This court reviews the district court’s summary judgment ruling de novo.
See Kendall Jackson Winery Ltd. v. E & J Gallo Winery, 150 F.3d 1042, 1046 (9th
Cir. 1998). To prevail on a claim for false arrest under the Fourth Amendment or
California law, a plaintiff must “demonstrate that there was no probable cause to
arrest him.” See Norse v. City of Santa Cruz, 629 F.3d 966, 978 (9th Cir. 2010)
(quoting Cabrera v. City of Huntington Park, 159 F.3d 374, 380 (9th Cir. 1998)
(per curiam)); Cornell v. City & County of San Francisco, 17 Cal.App.5th 766, 788
(2017). A probable cause inquiry “merely asks whether, under the totality of the
circumstances, a prudent officer would have believed there was a fair probability
that [a person] committed a crime.” United States v. Collins, 427 F. 3d 688, 691
(9th Cir. 2005).
Because Willis has not established a genuine dispute of material fact
whether Defendants had probable cause to support his arrest, Willis’s false
imprisonment and malicious prosecution claims fail as a matter of law. In the 32
hours between the victim’s assault and Willis’s arrest, law enforcement gathered
evidence against Willis that included a composite sketch formed from the victim’s
2 24-3154
recollection, the victim’s identification of Willis in a photographic lineup, and the
identification of Willis by two independent citizens based on the composite sketch
released to the media. Under a “totality of the circumstances,” the evidence was
sufficient to support Willis’s arrest on December 4, 2019 because a reasonably
prudent officer would believe that there was a fair probability that Willis had
assaulted the victim. District of Columbia v. Wesby, 583 U.S. 48, 57 (2018).
That later evidence pointed law enforcement in a different direction and
cleared Willis of the crime does not negate a finding of probable cause at the time
of Willis’s arrest. See, e.g., McSherry v. City of Long Beach, 584 F.3d 1129, 1135-
36 (9th Cir. 2009) (holding that a victim’s identification and information alone can
support a finding of probable cause to arrest); Peng v. Penghu, 335 F.3d 970, 976-
78 (9th Cir. 2003) (finding probable cause to arrest based on one witness providing
sufficiently detailed facts regarding the incident).
Willis contends that facts left out of Detective Luevano’s arrest warrant
affidavit create genuine disputes of material fact which precluded the district
court’s grant of summary judgment. We disagree. Under a “judicial deception”
theory of liability, a plaintiff must show that “but for” the misstatement or
omission, probable cause would have been lacking. Liston v. County of Riverside,
120 F.3d 965, 973 (9th Cir. 1997). Here, although the omitted information may
have proved relevant to a reviewing magistrate, we agree with the district court
3 24-3154
that “this information collectively [did] not vitiate the existence of probable cause
to issue the arrest warrant.” See Ewing v. City of Stockton, 588 F.3d 1218, 1224-25
(9th Cir. 2009) (holding that warrant application’s false statements about the
plaintiff were not material because an independent source was sufficient to
establish probable cause); Lombardi v. City of El Cajon, 117 F.3d 1117, 1126-27
(9th Cir. 1997) (holding that warrant application which failed to mention bias by
confidential informants nevertheless supported probable cause where the
informants’ statements were detailed and given independently); Smith v. Almada,
640 F.3d 931, 938 (9th Cir. 2011) (finding probable cause despite omission of
certain facts from arrest warrant application).
Moreover, the Constitution does not require a law enforcement officer
executing a search warrant “to investigate independently every claim of innocence,
whether the claim is based on mistaken identity,” “[n]or is the official charged with
maintaining custody of the accused named in the warrant required by the
Constitution to perform an error-free investigation.” Baker v. McCollan, 443 U.S.
137, 145-46 (1979). Thus, despite later obtained evidence which cleared Willis of
his criminal charges, no reasonable jury could have found that officers lacked
probable cause to arrest Willis. Summary judgment was appropriately granted.
AFFIRMED.
