KEYES (CBS13) — A second suspect has been arrested in the shooting that left a 16-year-old innocent bystander dead in Keyes last month.

Investigators had already arrested 19-year-old Keyes resident Ruben Perez in connection to Evan Robinson’s May 2 killing. Detectives say some sort of fight happened just before gunshots rang out near some taco trucks.
