Unreported / Non-Citable
Background
On December 1, 2024, at 9:38 p.m., Antioch police dispatch received an anonymous call reporting gunshots near an apartment building, corroborated by a ShotSpotter activation indicating gunfire in the same area. At 9:49 p.m., a second anonymous call described the individuals involved as Black male adults still at the complex. Officers Joseph Amiri, Jonathan Downie, and Ryan Tryner arrived around 9:58 p.m. and found Breshawn Clark, a Black man, with two women in the parking lot behind the building; no one else was present.
As the officers approached with a weapon drawn and commanded the group not to move, Clark walked away despite repeated orders to stop, touching and moving his hands along his waistband—which Officer Amiri testified, based on training and experience, usually indicated an attempt to conceal a weapon. After about 15 seconds Clark stopped. Officer Tryner's pat-down search revealed a large object on Clark's upper torso that Clark identified as an AR-15 firearm. Clark was arrested and charged with unlawful possession of an assault weapon (Pen. Code, § 30605, subd. (a)), carrying an unregistered loaded handgun (§ 25850, subds. (a) & (c)(6)), and possession of a short-barreled rifle or shotgun (§ 33215).
Clark moved to suppress the firearm under Penal Code section 1538.5, arguing the officers lacked reasonable suspicion for the detention and that the pat-down was unjustified. The magistrate denied the motion at the December 16, 2024 preliminary hearing, finding reasonable suspicion based on the totality of the circumstances. The trial court denied Clark's renewed motion, stating it was bound by the magistrate's findings and saw nothing in the transcript conflicting with them. On February 19, 2025, Clark pled no contest to carrying an unregistered loaded handgun under a plea agreement; the other two counts were dismissed, and he received two years' probation and a time-served sentence of 80 days in county jail. He appealed the denial of the motion to suppress.
The Court’s Holding
The Court of Appeal affirmed. It held that the seizure occurred when Clark heeded the officers' directives to stop walking away, submitting to a show of authority such that a reasonable person would not have believed he was free to leave. Because the motion was made before the magistrate and no new evidence was presented to the superior court, the court deferred to the magistrate's factual findings if supported by substantial evidence while independently assessing the Fourth Amendment issue under the totality of the circumstances.
The court concluded the officers had a particularized and objective basis to suspect Clark was involved in the reported shooting. The first anonymous call was corroborated by the ShotSpotter activation in the same area, making the tip reliable in its assertion of illegality under Florida v. J.L., and the second call describing the suspects as Black male adults was contemporaneous with the criminal activity, weighing in favor of its veracity under Navarette v. California. The officers arrived within minutes and found Clark was the only person present who matched the description.
The court also relied on Clark's evasive behavior—walking away despite commands to stop, changing direction, and manipulating his waistband in a manner Amiri testified could indicate concealing a weapon. Citing People v. Brown, the court held it was reasonable to briefly detain the sole person at the scene of a very recently reported shooting who matched the suspect description and exhibited such behavior. The court rejected Clark's argument that the roughly 10-minute response time distinguished Brown's three-minute response, and noted that although Clark did not challenge the pat-down itself, the magistrate's finding that it was justified for officer safety was supported by substantial evidence.
Key Takeaways
- Corroborated anonymous tips, such as a gunshot report confirmed by ShotSpotter plus a contemporaneous suspect description, can supply the reliability needed for reasonable suspicion.
- Walking away from officers while ignoring commands to stop and manipulating one's waistband is evasive behavior that contributes to reasonable suspicion under the totality of the circumstances.
- When no new evidence is presented to the superior court, appellate review of a magistrate's suppression ruling defers to factual findings supported by substantial evidence but independently reviews the Fourth Amendment question.
- A roughly 10-minute response time does not undermine reasonable suspicion where the tip indicates suspects remain on scene and officers find someone matching the description.
Why It Matters
This unpublished decision applies settled reasonable-suspicion doctrine to a shooting response: corroborated anonymous tips plus evasive conduct justified a Terry stop, and the protective pat-down was valid for officer safety. It illustrates how courts weigh ShotSpotter corroboration, contemporaneous tips, and an officer's experience-based inferences under the totality of the circumstances, and it shows the deferential review given to a magistrate's suppression findings when the superior court heard no new evidence.
