UPDATE, 5 p.m.: North Park Elementary teacher Karen Elaine Smith and 8-year-old Jonathan Martinez were pronounced dead after a gunman opened fire in Smith's classroom in San Bernardino, California this morning. Cedric Anderson, Smith's husband, walked into the classroom and shot his wife and two students standing behind her before taking his own life, The Los Angeles Times reports.

Martinez was airlifted to the Loma Linda Medical Center and was later pronounced dead. San Bernardino Police Chief Jarrod Burguan told the Times that another wounded 9-year-old student remains hospitalized in stable condition.

The shooting occurred in a classroom for students with intellectual disabilities, said San Bernardino Unified School District spokeswoman Maria Garcia. There were 15 students from first through fourth grades in the room, and two adult aides, Burguan said.

The chief said the couple had only been married for a few months, and he described them as “estranged.” Burguan said Anderson was armed with a high-caliber revolver.

From NBC News:

"There was no indication the gun was visible upon his arrival at the school," [Police Capt. Ron] Maass told reporters, referring to the gunman. Anderson had told the school he had come to drop something off for Smith, Burguan said.

Authorities are looking into Anderson's criminal background, which includes domestic violence and weapons charges. A .357 revolver was found next to Anderson, who is believed to have fired six rounds before reloading, Burguan said.



ORIGINAL POST: The Los Angeles Times reports that two adults were killed and two students were injured after a shooting took place in a classroom at North Park elementary school in San Bernardino this morning. Local law enforcement officials are describing the situation as a murder-suicide, the paper reported. Details about the students' conditions weren't immediately reported.

One suspect "was possibly down as well," San Bernardino Police Chief Jarrod Burguan told the LA Times.

From NBC News:

A short time later, police reported the "current threat at North Park ES has been neutralized."

The names and ages of the four people involved were not immediately known.

This is at least the second shooting in San Bernardino to make national news in nearly two years. In December 2015, 14 people were fatally shot at a local developmental disabilities facility.

Violence in the city is skyrocketing, too.

"There were 62 slayings in San Bernardino in 2016 — a 41% increase from the year before," the Times reports. "It was the deadliest year in the city since 1995."
