A gunman has killed at least five people in Tehama County, California, in a shooting spree that ended at an elementary school, according to LA Times.

“The suspect was actually shooting at the police vehicle, back at them, the officer rammed the vehicle, forced it off the road, an exchange of gunfire — resulting in the shooter’s death,” said Tehama County Assistant Sheriff Phil Johnston.

At one point, the gunman attacked a local elementary school. Witnesses said he crashed through the school’s gates with his truck and opened fire on walls and classrooms.

Phil Johnston, Tehama County Assistant Sheriff, told reporters that a number of students were medically evacuated from the school.

“We have about 100 law enforcement personnel in Rancho Tehama right now, with multiple, multiple scenes,” Johnston said.

Nearby witnesses said they heard at least 100 gunshots.

The issue of owning private guns in the U.S is a massive political issue in the U.S.

According to statistics from VOX, the US has by far the highest number of privately owned guns in the world.

It was estimated in 2007 that the number of civilian-owned firearms in the US was 88.8 guns per 100 people, meaning there was almost one privately owned gun per American and more than one per American adult.
