A man was stabbed to death Tuesday night at Red Bluff River Park and the killer is still at large. At around 7:30PM multiple 9-1-1 callers reported a man running around trying to stab people. When Red Bluff Police arrived they found 37-year-old Jonathon Emerson near the pool suffering from a single stab wound to his chest. EMT’s provided first aid and transported him to Saint Elizabeth Hospital, but he died after arriving. Detectives have apparently not made an arrest, nor has any information been released about the suspect.
