At around 4 pm on August 15, the Fontana police received a report about a shooting at a home on Colonial Drive, near the Sierra Lakes Golf Club.

According to Officer Daniel Romero, a Police Department spokesman, Diaz's wife told the police that he had fired a gun at a wall inside their house, but fortunately, no one was hurt.

Afterward, Diaz left the home with a gun. People later saw a man with a gun near the Sierra Lakes clubhouse, which was close to his home. Fontana police then confronted Diaz, which led to the tragic outcome.
