Five people have been killed and 10 others have been hospitalized in Tehama County after a shooting.

The gunman is said to be one of the five people dead.

There were at least 100 law enforcement officers at the scene, said a Tehama County sheriff's deputy. The FBI is also sending teams at the request of Tehama County authorities, according to a representative at the FBI's Sacramento field office.

Where did the shooting happen?

The shooting happened in Rancho Tehama Reserve, a small community about 15 miles southwest of Red Bluff. The location a rural subdivision surrounded by open land and trees with the closest big city being Chico-- about an hour away.

Rancho Tehama has a total population at 1,485 people, according to the 2010 United States Census. The census reports 83 percent of the population is over the age of 16. The 2011-15 American Community Survey estimated 891 total housing units for the area.

A Tehama County undersheriff said, officials processed "seven or more crime scenes." Law enforcement officials confirmed the shooting started at a home off of Bobcat Lane and one of the other locations was near a school.

Rancho Tehama resident, Salvador Tello, told the Record Searchlight that "he was taking his three children to Rancho Tehama Elementary School when the gunman fired at a truck in front of him." Another resident, Katrina Gierman, who has a newborn and lives near the elementary school, said she heard gunshots when she walked outside.

Rancho Tehama is described as a “quiet private country community” on its website, but neighbors of the gunman said he was threatening and harassing them.

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

The suspect's motive is still unknown as the investigation continues.
