Gonzales, 51, was among the first officers to arrive. He was indicted on 29 charges that accuse him of abandoning his training and not confronting the shooter, even after hearing gunshots as he stood in a hallway.

Arredondo, 53, was the on-site commander that day. He is charged with 10 state jail felony counts of abandoning or endangering a child. Arredondo failed to identify an active shooting, did not follow his training and made decisions that slowed the police response to stop a gunman who was “hunting” victims, according to the indictment.
