The man suspected of fatally shooting four people and injuring 10 more, including two children, in a remote Northern California town reportedly had a criminal history and was reportedly out on bail for stabbing a woman when he went on a shooting rampage Tuesday morning.

KHSL reporter Cecile Juliette said in a live video feed from Rancho Tehama that witnesses who knew the shooter spoke of the suspect’s criminal past and that he was well known to authorities. She said that police had frequently visited the suspected gunman, who has not been identified, at his home due to his reported habit of firing off his “many many” guns.

It is unclear when the stabbing happened or how seriously the victim was injured.

Brian Flint told local USA Today affiliate the Record Searchlight that he lived next door to the suspected gunman, who he said shot his roommate at the start of his killing spree. He then allegedly stole multiple vehicles. After a shootout with police, he was found dead in one of those vehicles with two shotguns and a semiautomatic weapon inside the car.

Flint told the news outlet that living next to the suspect was “hell” and that he allegedly harassed his neighbors and was generally a menace.

“The crazy thing is that the neighbor has been shooting a lot of bullets lately, hundreds of rounds, large magazines,” Flint said. “We made it aware that this guy is crazy and he’s been threatening us.”

None of the victims who have died are children, though law enforcement has said it is possible the death toll will rise.
