Shooting at Elementary School in San Bernardino, California

"Triage and victim count taking place," the San Bernardino County Fire District said. There have been multiple gunshot wound victims, officials noted.

The school is currently on lockdown, as is nearby Cal-State Bernardino University. 

The SB police chief said four people are currently being treated by first response medical crews. 

​The incident may have stemmed from a domestic violence dispute involving a teacher, a spokesperson told NBC Los Angeles. It is believed to be a murder-suicide but multiple people were shot. 

The two injured students have been sent to the hospital for further treatment.

Students of North Park Elementary have been shuttled to a nearby high school for safety, the police chief said. 

​The gunman and teacher have been reported dead, while the two children were injured. The shooter committed suicide, according to local police. The San Bernardino Mayor stated that one of the two deceased was the suspect, stoking suspicions that the case was a murder-suicide. The two students are in critical condition after sustaining gunshot wounds, while one man and one woman have been confirmed dead. The man was let into the school to visit the teacher.

The suspect did not aim to attack students, the county's police Cpt. Ron Maass said in a press conference on Monday.

"The children we do not believe were targeted," Maass stated. "The suspect had come to the classroom to visit. The adult female was in the classroom."

Maass explained that upon entering the building, the suspect checked with the front office, where he believed to be known by the staff.
