CHINO ( — Two Los Angeles County Sheriff’s deputies have been relieved of duty after a reported argument over loud music at a Chino campground erupted in gunfire, according to reports.

KNX 1070’s Pete Demetriou reports neither of the men allegedly involved knew the other was a colleague at the department until after the incident.

Dejay Barber, 44, and Matthew Rincon, 24, were arrested Sunday morning after police responded to reports of shots fired at the Prado Regional Park.

The shots were fired into the air and no one was hurt, the Los Angeles Times reported.

The deputies, who were camping separately, did not learn they were colleagues until after their dispute, according to The Times.

Barber and Rincon were booked on charges of negligent discharge of a firearm.

Sheriff’s spokesman Steve Whitmore said both men have been suspended with pay and assigned to home duty while an administrative review is conducted to determine if there will be further disciplinary measures.

“It could be suspended without pay, it could be things along those lines, we just have to wait and see,” Whitmore said.

Alcohol may have been a factor in what appeared to be a case of “gross negligence,” Whitmore told the Times.

Both the criminal and administrative process may proceed together if Chino police share the evidence in the case, Demetriou reported.
