SISTERS, OR -- The Deschutes County Sheriff's Office is looking for a man they believe made threats against a school in Sisters. Investigators say 41-year-old Charles Matthew Schmiel made a vague threat against an unnamed school on May 5, leading to an increased law enforcement presence at all Sisters schools. Deputies again performed security checks at all Sisters schools Friday before students and staff arrived. They say they found nothing suspicious. 

They say Schmiel does not have a permanent address and may be camping in the area. Anyone who knows Schmiel's whereabouts is asked to call the Sheriff's Office at 541-693-6911, reference case 22-23618.
