A California man drove to the police station on Monday with a dead body in his car and confessed to killing four others, including the one in his four-wheeler which was parked outside.

The suspect, whose identity has not been revealed by the police, drove to the Mt. Shasta Police Department on Monday afternoon. There he confessed to killing four relatives in his apartment, which was around 200 miles from the police station. He told the police that he carried one of the bodies with him in his car. 

“He just came in and told our dispatcher that I want to confess to a murder, and then just gave it up,” Sergeant Gibson, who was in the station when the suspect turned himself in, told New York Times. “I have never had someone come in with a body and turn themselves in here. This was unusual for us.”

After getting the man’s confession and detaining him, the Mt. Shasta police called Roseville officers who then found three bodies in the man’s apartment when they checked it.

The identification of the victims has not been revealed by the police.

The suspect remained in custody on Monday night, though he was not charged with the murders yet.

Captain Josh Simon of the Roseville Police Department said in a press conference on Monday that an investigation is being conducted with the co-ordination of Mt. Shasta police.

"The sole suspect involved in this incident is in custody and we do not believe there is any ongoing threat to our community," Simon said. "This can really have an effect on all our first responders and people who may or may not know these victims. So this is a very heavy impact to our community."

The police have not been able to determine the motive behind the man's actions. They are currently trying to obtain warrants for searching his apartment and his car.
