Police didn't immediately release details about the suspect's grandmother, but say 52-year-old John Herrick, of Erie, made the call from his cell phone at 11:16 p.m. Monday. They say Herrick claimed there was a bomb near a hospital exit, but police found nothing.
Police used information from cell phone towers to locate Herrick who was arrested on charges of making terroristic threats and risking a catastrophe early Tuesday.
He's in the Erie County Jail. Online court records don't list an attorney for Herrick.
