Deputy Sheriff Jack Don Williams of the Los Angeles County Sheriff’s Department was killed on May 29, 1979, during a narcotics raid in La Puente, California. Williams and other members of the Narcotics Bureau were executing a search warrant when suspects inside opened fire; one of the shotgun blasts fatally struck Williams during the forced entry.

The shooter was identified as Jesse Gonzalez, described as a member of the Mexican Mafia. Gonzalez was arrested and charged with murder; at trial he said he believed the plainclothes officers were rival gang members coming to kill him. He was convicted of first-degree murder with the special circumstance of killing a peace officer and later sentenced to death.

Williams had served nine years with the Sheriff’s Department and was survived by his wife and two children. What additional information can anyone offer about Deputy Williams’ service or the events at the La Puente residence?
