At least four people have been shot in an apparent murder-suicide plot at an elementary school in San Bernardino, California.
Reports are still sketchy, but at least two people have been taken to a nearby hospital. There's no word on any fatalities, whether the targets were children or teachers, or the identity of the shooter -- or if he or she is still alive.
San Bernardino was the site of an ISIS-inspired mass shooting in 2015 in which 14 people were killed and 22 others were injured. (KTLA-TV)
