Police say they've arrested Donald Dokins in connection with the June 4 shooting. The Los Angeles County District Attorney's Office says 14-month-old Angel Cortez was in his father's arms when a gunman rode up on a bike and fired several shots.
The baby died at a local hospital; his father was hit in the shoulder.
Dokins will be arraigned Friday and will be tried as an adult. If convicted, he could face several life sentences.
