Two adults are dead in an elementary school classroom and two people have been taken to hospitals after a shooting, San Bernardino Police Chief Jarrod Burguan says.

San Bernardino County fire spokesman Eric Sherwin said the shooting happened Monday morning at the North Park School in the city.

“Two adults are deceased in a classroom, believed to be a murder suicide,” Burguan tweeted. “We believe the suspect is down and there’s no further threat.”

Burguan said that two people, possibly students, were wounded.

San Bernardino County Fire said earlier that it was on the scene and that triage and victim count was taking place.

Burguan said there was a “large police response” and that students at the school were being taken to Cajon High School “for safety.”

The school was placed on lockdown. The shooter was reportedly taken down a few blocks away from campus.

The motive for the incident is under investigation.
