Santa Clarita, California, high school shooting leaves 1 dead, multiple injured

One person is dead and at least three others are injured, two of them critically, after a shooting at a Southern California high school Thursday morning, officials said.

About an hour and a half after the shooting was reported at about 8 a.m. before classes started at Saugus High School in Santa Clarita, authorities said they had located the suspect who was no longer a threat.

"This is an active shooter situation," a tweet from the Santa Clarita Valley sheriff's office said before the suspect was located. "If you live in neighborhoods anywhere near Saugus High, PLEASE LOCK DOORS and stay inside. If you see suspect, male dark clothing, in backyards, etc. CALL 911."

"Parents, deputies are on scene everywhere protecting your children," a tweet from the sheriff's office said.

The Santa Clarita Valley sheriff's office tweeted just before 8 a.m. local time to avoid the area of Saugus High School, which is in the county of Los Angeles, about 40 miles north of the city of Los Angeles. Minutes later, the office said people were reporting that shots had been fired at the school.
