LOS ANGELES — Detectives on Friday were investigating a possible domestic violence motive after a gunman shot and killed his ex-wife and four others before killing himself during a nearly 40-minute rampage in Southern California, authorities said.
Javier Casarez fatally shot himself as a deputy closed in on him after the killings in Bakersfield, about 90 miles (145 kilometers) north of Los Angeles, Kern County Sheriff Donny Youngblood said Thursday.
Casarez, 54, shot his ex-wife and a man at a trucking company before chasing after another man, killing him, and then driving to a home where he shot dead a father and daughter on Wednesday.
Court records show a divorce between Casarez and Petra Maribel Bolanos de Casarez was finalized earlier this year.
In his petition for divorce filed in December, Cesarez accused Bolanos of cheating and asked the judge for his wife's text messages to specific phone numbers. The judge denied the request.
Bolanos recently filed for a change involving child support and custody over the couple's two teenage children, and the pair had a hearing set for Oct. 11, court records show.
Youngblood said it appears that Casarez targeted every victim, starting with a worker at T&T Trucking, and that domestic violence appears to have played a large part.
"It appears to be there's more than just husband and wife having a fight because other people were targeted," he said. "There's a reason for that and we need to find that reason."
Investigators are looking into whether Casarez's ex-wife may have had relationships with Contreras or Valadez, the sheriff said.
Casarez likely took his ex-wife to the trucking company against her will and then fatally shot 50-year-old Manuel Contreras with a .50-caliber handgun, authorities said. He shot his ex-wife and then turned the gun on a second man, 50-year-old Antonio Valadez, the sheriff's department said.
Casarez fired at Valadez as he ran away, but then tracked him down in his car and killed him, the sheriff said.
Casarez then drove to the house of 57-year-old Eliseo Garcia Cazares, who Youngblood identified as a friend. Casarez fatally shot Garcia and his daughter, 31-year-old Laura Garcia.
"She may have tried to intervene to keep the suspect from approaching her father, and he shot and killed both of them," Youngblood said.
After the shooting at the Garcia home, Casarez carjacked a woman driving with her child. The woman and child escaped, and Casarez drove to a highway where a sheriff's deputy saw him, Youngblood said.
As the deputy closed in, yelling at Casarez to drop his gun, Casarez fatally shot himself in the stomach, according to graphic body camera footage released by police on Facebook.
The video shows deputies and paramedics working to save Casarez. Deputies look over Casarez's gun and talk about how he would have had to reload it during the rampage.
David Bunting, who said he's a friend of Eliseo Garcia Cazares and lives two doors down from him, said he has no idea why his neighbor would have been targeted.
He said Garcia was a self-employed truck driver who always was with his grandkids when not working, often driving them around on his golf cart.
"He's a really nice guy. I can't say enough good things about him," Bunting said. "It's kind of a shock because of the kind of a person he was."
