The Sheriff’s Department received a call around 6 p.m. about a man who said he was armed with an AR-15 rifle and a bomb at the hospital, was experiencing a mental health crisis and heard voices in his head that told him to shoot patients at the children’s hospital, Dicus said.

Reports of a possibly armed person at a San Bernardino, California, hospital sparked a massive law enforcement response Wednesday evening, but authorities later cleared the scene and said it appeared to be the result of a "swatting" call.
