Stunned residents filled the sidewalk of a modest East Los Angeles neighborhood with candles, flowers and other tributes at the site where a man parked the SUV in which he had killed his girlfriend, their 5-year-old twins and then himself.
The deadly outburst began late Saturday when Salvador Acevedo and his girlfriend, Iris Oseguera, got into an argument as they rode in the car with their fraternal twins and three other children. The three, described only as adolescents, were spared.
Police say Acevedo, 45, was driving when he and his 33-year-old girlfriend got into an argument and he pulled out a handgun and began shooting.
After the killings he drove the three surviving children to a relative's home and dropped them off. After he drove away, police said, the children told an adult what had happened and authorities were called.
Sheriff's Sgt. Michael Thomas said deputies found Acevedo's vehicle parked nearby.
He and Oseguera were pronounced dead at the scene. The boy and girl were rushed to Los Angeles County-USC Medical Center, where they were pronounced dead.
A handgun was recovered at the scene, and Thomas said it appeared Acevedo shot himself after the others were killed.
Acevedo and Oseguera were the parents of the twins, but their relationship to the other three children was not immediately known.
