A Minnesota Security Hospital patient has been charged with attempted murder for allegedly stabbing his mother while on a pass at a nearby park. 48-year-old Burton James Ewing Jr made his first appearance in Nicollet County Court on Thursday, and his bail was set at a million dollars. Ewing was reportedly in a transition program at the St. Peter hospital for adults classified as mentally ill and dangerous. He had left the facility on a pass with his mother at about 3pm Tuesday, and was arrested at 7 Mile Creek Park south of St. Peter about two hours later after sheriff’s deputies found him allegedly stabbing the woman. Marlys Helen Olson remains in serious condition at a Minneapolis hospital after being stabbed a total of 22 times in her head, throat and chest. Ewing killed his sister in 1998, but was found not guilty by reason of mental illness. His next court appearance on the attempted murder charge is scheduled for this coming Tuesday.
