At about 12:55 a.m. local time on Saturday, police received a 911 call reporting a shooting, and officers responded to a "large outdoor party" where they learned an "altercation occurred just prior to their arrival," according to a Gilroy Police Department press release. At least one suspect had fired a gun, authorities said, and there were four people shot. One male victim was pronounced dead at the scene. The other three — two of whom had "life-threatening injuries" — were taken to nearby hospitals. The shooting victims ranged in age from 17 to 19. The altercation happened at the residence of Gilroy City councilperson Rebeca Armendariz. On Sunday, the Gilroy/Morgan Hill Regional SWAT team executed a search warrant and arrested 19-year-old Benjamin Calderon in connection with the fatal shooting. Police said Calderon is charged with homicide, according to jail records, is currently being held without bail and is due in court on Wednesday. Want to keep up with the latest crime coverage?
