Trevon Ryan was 27 and a resident of San Ysidro when he was shot and killed on April 4, 2020. The shooting occurred at an apartment complex on Servando Avenue as Ryan walked down a stairwell; he was found in the courtyard and died at a hospital after being transported amid medics’ delays.

Police say the suspect was 19-year-old Daniel Juarez, visiting family in San Diego from Georgia. Officers had been summoned earlier for reports that Juarez was threatening self-harm and behaving erratically on a balcony. They called a SWAT team because they suspected he might be armed; after a standoff he surrendered and was booked on suspicion of murder without bail. Investigators reported no clear motive and said Ryan and Juarez appeared not to know each other. Toxicology and other evidence were being evaluated and authorities asked the public for tips.

Did anyone see activity at the Servando Avenue complex that day or have information about either man’s movements leading up to the shooting?
