A homeless Yreka man has been given a long prison sentence for threatening people with a knife. Two years ago, 32-year-old William Isaac Miller had an apparent psychotic episode behind Yreka’s old JCPenney building. He started harassing and threatening people, some of whom were living in their cars. When Miller pulled a knife and started chasing people, police were called. They arrived as he was pounding on someone’s window and he was arrested. Miller, who has been convicted of crimes in five other states, requested mental health diversion but was denied despite having a qualifying mental disorder. The court cited alcohol as the main factor in the crimes. After pleading no contest, Miller has been sentenced to over 18 years in state prison.
