New Hampshire authorities say a teenager has been found not guilty by reason of insanity in the fatal stabbing of his mother.
Police said 42-year-old Melissa Hatch, of Madison, was found dead in her home in February. Her son, Keith Dobens, who turns 18 Friday, was charged with second-degree murder. He appeared in court Thursday
A judge in Carroll County Superior Court agreed the parties have shown that Dobens still suffers from a mental disease or defect and poses "a substantial risk of bodily injury to others."
Dobens is being committed to a secure psychiatric unit for five years.
