Sergio Mendez, 34

Sergio Mendez, 34, a Latino man, was shot in a double-homicide that also took the life of victim Joseph Vargas, 31. He suffered bullet wounds to the chest and abdomen, and died at 3:20 a.m. Friday, July 27.

Both men were shot in the 1500 block of Navarro Avenue in Pasadena at about 1:50 a.m. They were taken to a local hospital, where they died.

Pasadena police spokeswoman Janet Givens said officers got word of an argument that escalated into a fight. A suspect or suspects shot the men, then fled. Detectives later arrested three people in Covina: Jonathan Warren, 22, Diana Reyes, 20, and a youth or boy whose name was not released. Gang concerns were at issue, investigators said.
