Almanza was charged with multiple counts related to the shooting, including first-degree murder and attempted murder.

According to court documents, a custody dispute between Almanza and the mother of his children led to a fight in the street. According to an arrest affidavit, Almanza told investigators that he didn't know police officers were present when he started shooting.

Almanza is also accused of shooting a woman in the leg during the same incident.
