"We have six people dead, five victims and one suspect", Youngblood said.
The sixth killing occurred when the suspect eventually turned on himself with a gunshot to his chest as deputies closed in to confront him at a parking lot.
Multiple law enforcement agencies are investigating the shooting spree.
According to the Californian, Youngblood said the suspect went to a trucking business with his wife and confronted another male.
The tragedy began Wednesday afternoon at a trucking business, where the attacker used a handgun to shoot and kill his wife and another man.
Another man then appeared at the scene and the husband shot at him, before pursuing him and shooting him dead.

The free and fair election is the essence of democracy, a right that free men in this country and others have died to preserve. Doug Ford is the kind of politician who doesn't mind stirring up a little needless chaos.
Then the gunman confronted two more people at a different location, he said.
Investigators said he next stole a vehicle with a woman and child inside, but they were not harmed. "It was a very short period of time, maybe 10-15 minutes".
Bakersfield is about 100 miles northwest of Los Angeles.
Authorities say a man who killed five people, including his wife, in Bakersfield, California, was in the midst of divorce proceedings. The suspect missed on the first shot but chased down the employee and killed him, according to reports. The woman and child made it out safely and were able to escape from the vehicle, Youngblood said. The gunman killed himself as a deputy approached.
Youngblood said police recovered a pistol at the scene.
According to the AP, there is no word on how the other victims were related. Authorities were interviewing about 30 witnesses.
While there is no known motive at this time, Lt. Mark King of the Kern County Sheriff's Office says that police believe that the shooting was a case of domestic violence.
