The mass murder unfolded about 5:20 p.m. Wednesday when an unidentified man and his wife confronted a man at a trucking company, according to Kern County Sheriff Donny Youngblood.
A gunman in California Kern County killed five people, including his wife, before turning the gun on himself as a sheriff's deputy closed in, authorities said.
The dead include five victims and a suspect, the sheriff told the Bakersfield Californian.
After that, investigators say the husband went to a home on Breckenridge Road and shot two people inside.
He commandeered a vehicle before he killed himself when he was confronted by a sheriff's deputy.
According to police, the shooter killed himself when confronted by a deputy.
"Six people lost their lives in a short period of time", Youngblood said.
"I'm certainly speculating right now", Youngblood said. The woman was riding with her child.
He indicated there are multiple crime scenes, including one near a gun seller called Bear Mountain Sports. Authorities were interviewing about 30 witnesses.
Finally, he carjacked a mother and her child, but they were not injured, according to reports.
"It's highly unusual to have six people killed in one incident", the sheriff said. A victim happened to be in the area and was chased around the building before being shot, Youngblood said.
The gunman's identity was not immediately released, and it was also not immediately known how he was related to the victims other than his wife.
He added: "This is the new normal, if you look around the country".
Bakersfield is about 100 miles northwest of Los Angeles.
Reuters reported the police recovered a pistol at the scene.
