United States v. Estrella, 3:19-cr-00517

Background:

Defendant Christian Estrella was indicted for being a felon in possession of a 9mm Ruger and ammunition following an August 14, 2019 encounter with Lakeport police; he moved to suppress evidence as obtained by unlawful seizure/search.
Officer Tyler Trouette (Lakeport PD, Lake County Gang Task Force) had prior contacts with Estrella: Estrella registered as a gang member in July 2018, Trouette performed a parole compliance check at his home, and Trouette spoke multiple times with Estrella’s parole officer in 2018–2019.
On August 14, 2019 Trouette and Officer Cooley approached Estrella on the street; Trouette observed Estrella wearing an Oakland A’s hat (which Trouette associated with Estrella’s gang and a parole-violation), and the officers spoke with him.
During the encounter Estrella said he was on parole; dispatch then confirmed Estrella was on CDC parole and flagged as a felon and gang member; Estrella told officers there was a gun in his car and that it was in the center console.
Officers handcuffed Estrella, conducted a pat search, opened the vehicle, and recovered a loaded Ruger 9mm from the center console.
The district court denied the motion to suppress, finding Trouette had advance knowledge that Estrella was subject to California’s parole-search condition, the searches were supported by that condition (confirmed by dispatch/Estrella), and the searches were not arbitrary or harassing.

Issues:

Issue	Plaintiff's Argument	Defendant's Argument	Held
Validity of initial encounter/detention	Encounter was a seizure; officers lacked parole knowledge at inception so detention/search unlawful	Officers seized Estrella without advance, objective knowledge of parole status	Court: Trouette had sufficient prior knowledge of parole status; detention justified (assumed arguendo seizure)
Lawfulness of warrantless search under parole-search condition	Search invalid because Cooley did not know parole status at inception and Trouette lacked objective confirmation	Government: suspicionless search lawful if an officer had advance knowledge that §3067 applied; confirmation by Estrella/dispatch further justified search	Court: parole-search condition applied; Trouette’s prior contacts and reasonable belief satisfied advance-knowledge requirement; search lawful
Collective-knowledge imputability	N/A (defense emphasizes Cooley’s ignorance)	Government: Trouette’s knowledge imputable to Cooley under collective-knowledge doctrine	Court: Trouette’s knowledge (and later confirmation) justified actions; collective-knowledge doctrine supports imputing knowledge between officers
Whether search was arbitrary, capricious, or harassing	Search was a training exercise (using Estrella as a "guinea pig") and thus arbitrary	Government: officers acted for legitimate law-enforcement purposes (parole compliance, gang info, public safety)	Court: no evidence of harassment or improper purpose; searches not arbitrary or capricious
