Richard Ryan was 29 and a resident of Union City when he was shot and killed on September 11, 2015, in Oakland, California. The shooting occurred in the 8300 block of International Boulevard as Ryan was reportedly leaving a store; several men approached and opened fire for reasons that remain unclear. His death was one of four homicides the Oakland Police Department counted during an especially violent week in the city.

No arrests have been made in Richard Ryan’s killing, and police have not released descriptions of suspects or a motive. The shooting took place about a block from where Rey D. Flores was killed a few days earlier, a proximity that has been noted in accounts of violence on that stretch of International Boulevard.

If anyone saw Richard Ryan that day or has information about the shooting in the 8300 block of International Boulevard, please share what is known with investigators.
