A former Los Angeles County sheriff's deputy pleaded no contest today to killing a man in Sylmar more than four years ago, the Los Angeles County District Attorney's Office announced.

Francisco Gamez II, 45, entered his plea to one count each of second-degree murder and attempted murder. He also admitted a special allegation that he personally used a firearm.

Gamez was immediately sentenced to 25 years to life in state prison by Los Angeles County Superior Court Judge George Lomeli.

Deputy District Attorney Rosa Alarcon of the Justice System Integrity Division prosecuted the case.

On June 17, 2012, Gamez's son was involved in an altercation with 38-year-old victim Armando Casillas. After his son told him about the fight, Gamez drove up to Casillas and another man, firing two shots. Casillas was killed and the other man was not injured.

The case was investigated by the Los Angeles Police Department.
