A man who was found not guilty of a Hastings murder by reason of insanity must remain in the state psychiatric hospital. The judge made the ruling at the annual review for 36-year-old Jayson Garett. Authorities say Garett has a bipolar disorder and was in a manic phase when he stabbed to death 45-year-old Daryl Peed at Peed's home on March 27, 2004. Authorities say the two men didn't know each other. A hospital staff psychiatrist testified Tuesday that Garett had made progress but concerns remain.
