The rampage started when the suspect and his wife entered a trucking business near a gun shop at around 8 p.m. and opened fire on a man inside - killing him, according to The Bakersfield Californian.
Five people were shot dead by a gunman in Southern California late Wednesday in an attack that police say began as a domestic disturbance.
The shooting left 6 dead, including the gunman and his wife, Kern County Sheriff Donny Youngblood told reporters.
Authorities said the suspect then went to a residence on Breckenridge where he shot and killed two more people.
He then headed to a nearby highway where he saw a deputy and pulled over.
The Sheriff's Department said the shootings took only a short period of time and were not random.
"This is the new normal", said deputy Donny Youngblood. The shooter commandeered a vehicle with a woman and a child inside. Asked if this was a mass shooting, the sheriff said "absolutely".More news: Hurricane Florence webcams: Where you can watch the storm

Authorities are interviewing 30 witnesses and processing multiple crime scenes to piece together what led up to the violence.
"We have six people dead, five victims and one suspect", Youngblood said.
Bakersfield is about 100 miles northwest of Los Angeles. The suspect fired shots at this man, who fled.
Finally, he carjacked a mother and her child, but they were not injured, according to reports.
Investigators say the gunman later drove to a home, where he killed two other people.
"There was some type of situation that caused the husband to be extremely upset", he said. The three shootings all occurred at the trucking business near Bear Mountain Sports.
Reuters reported the police recovered a pistol at the scene.
