Week in Review : MAJOR EVENTS, IMAGES AND PEOPLE IN ORANGE COUNTY NEWS : CITIES : D.A. Weighing Charges Against Seven Santa Ana Officers in June 18 Gunplay

One source said that the Santa Ana police officers might have been “working off a little steam.” Another said it sounded like “one of those ‘choir practice’ type of things,” referring to the off-duty activities of cops portrayed in the novel “The Choir Boys,” by Joseph Wambaugh.

The remarks were made about a group of seven off-duty officers who allegedly fired shots that struck a county supervisor’s office June 18. The Orange County district attorney is expected to decide by Monday whether to bring criminal charges against them.

The results of a Santa Ana Police Department criminal investigation into the shootings were presented to the district attorney’s office Friday for review, Capt. Robert H. Stebbins said. A separate, internal investigation should be completed early next week, he added.

The Police Department refused to identify the officers involved in the early morning incident, which is believed to have been a celebration of the end of a probationary period for some rookie officers.

Sources close to the investigation, however, said that two of the officers were Scott Zimmerman and James Bland, both of whom have resigned from the force. Neither could be reached for comment, and it wasn’t clear if their resignations were tied to the inquiry.

According to the sources, a group of officers drove to the roof of the Orange County Transit District parking garage on Santa Ana Boulevard after a night of drinking.

Five of the officers fired their weapons shortly before 3 a.m., the sources said, and two bullets struck windows across the street, lodging high in a wall in the office of Suzanne Victor, an aide to Supervisor Roger Stanton. No one was in the office.

A transit district security guard reported hearing shots, but a Santa Ana police officer sent to check out the shooting reported finding nothing 20 minutes later. The sources said that two officers who didn’t fire are not targets of the investigation.
