RANCHO TEHAMA RESERVE, Calif. — The wife of a gunman who went on a shooting rampage in a Northern California town was found dead inside their home, authorities announced Wednesday, raising the death toll from the attack to five.

Investigators discovered the body of Kevin Janson Neal’s wife hidden under the floor with several gunshot wounds. They believe her slaying was the start of the rampage, said Tehama County Assistant Sheriff Phil Johnston.

Neal shot and killed four other people and wounded 10 at different locations around the rural community of Rancho Tehama Reserve. Police later shot and killed him.

At the time of the attack, the gunman was out on bail after he was charged with stabbing a neighbor. Court records also show that Neal was barred in February from having guns after the assault.

Neighbors had complained about him firing hundreds of rounds from his house, and the assistant sheriff acknowledged officers had visited the home on several occasions.
