Michael Daniel Zuniga-Macias, 18, was shot and killed on October 30, 2021, during a Halloween party on the 400 block of Las Animas Avenue in Gilroy, California. The party was at the home of Gilroy City Councilmember Rebeca Armendariz; an altercation at the event escalated into gunfire. Zuniga-Macias was pronounced dead at the scene. Three other partygoers, aged 17 to 19, were wounded.

Investigators executed a search warrant at a Church Street residence and arrested 19-year-old Benjamin David Calderon on suspicion of homicide; as of early November 2021, the Santa Clara County District Attorney’s Office had not filed charges. Authorities said at least two shooters were believed to be involved, and no additional suspects had been publicly identified at that time. A memorial and candlelight vigil were held outside Armendariz’s home.

If anyone attended that gathering or has information about who fired the shots, please share what is known.
