UPDATED 11:36 a.m.: Los Angeles County Deputy Francisco Gamez II has been charged with murdering a neighbor who had fought with his adult son last June.
The district attorney's office says Gamez, 41, was charged Thursday morning with murder, attempted murder and discharging a weapon from an occupied vehicle.
Authorities say Gamez's 20-year-old son had an altercation with 38-year-old Armando Casillas and the son called Gamez. The deputy is accused of driving to the scene, confronting Casillas and another man and firing two shots. Casillas died and the other man was not hit.
Gamez was arrested Thursday. If convicted, he faces a maximum prison term of 75 years to life in prison.
PREVIOUSLY: LAPD detectives on Wednesday arrested a 17-year veteran of the L.A. County Sheriff's Department on suspicion of homicide.
Francisco Gamez was taken into custody for the fatal June 17 shooting of Armando Casillas. Police believe some sort of dispute led to the incident.
The alleged murder happened in Sylmar, on the 14000 block of Beaver Street, around 11:15 a.m. Bystanders flagged down a passing patrol car and led officers to Casillas, who had been shot. The 38-year-old was pronounced dead at Providence Holy Cross Hospital. A second person was shot at, but not hit.
Police say as the case progressed and suspicion fell on a deputy sheriff, the investigation transferred to the LAPD's Robbery Homicide division, which handles high-profile cases.
Sheriff's spokesman Steve Whitmore says once the department learned of the investigation on July 3, they immediately put Gamez on paid leave and stripped him of law enforcement powers. Starting Thursday, Whitmore says, Gamez will be on unpaid leave and removal proceedings may begin.
Gamez's latest role with the department was as a detective in West Hollywood.
"Obviously [Sheriff Lee Baca] is appalled," Whitmore said. "This casts a pall over the work that law enforcement and deputy sheriffs do."
Gamez is being held in lieu of $4 million dollar bail on charges of murder, attempted murder, and use of a firearm during the commission of a felony.
