At least two dead, two wounded in Southern California school shooting

LOS ANGELES - At least two adults were killed and two other persons, possibly students, were struck by gunfire in a classroom shooting on Monday at a Southern California elementary school, police and fire officials said.
San Bernardino Police Chief Jarrod Burguan said the shooting at Northpark Elementary School in San Bernardino, about 65 miles east of Los Angeles, appeared to a "murder-suicide," but details were sketchy.
"Two adults are deceased in a classroom," the chief said in a Twitter post, adding, "There are two wounded, possible students," who were taken to hospitals. He said their conditions were not immediately known.
"We believe the suspect is down, and there's no further threat," Burguan said.
Authorities did not immediately furnish additional details about the circumstances surrounding the shooting, or the identity and motive of the shooter.
ABC News, citing information from a police spokeswoman, earlier reported that three people, including a teacher, were hit by gunfire, in addition to the shooter.
