GILROY, Calif. (AP) — Authorities say a 19-year-old man has been arrested on suspicion of murder in connection with a fatal shooting at a city councilmember’s Northern California home.

One person died and three other people were injured. Authorities say Sunday that Benjamin David Calderon was taken into custody Saturday afternoon by a SWAT team after the late-night shooting in the city of Gilroy.

Police were called after violence broke out at a large outdoor party at the home of Gilroy City Councilmember Rebeca Armendariz, about 80 miles south of San Francisco. At least one suspect fired a gun.

It was not immediately clear if Calderon had an attorney who could speak on his behalf.
