Man suspected of beating homeowner during robbery seeks insanity defense

      EUGENE, Ore. -- A Eugene man accused of trying to kill a woman while robbing her house is now seeking an insanity defense.

      Tyler Kowalchuk's attorney filed paperwork in August indicating his client suffers from a mental defect.

      The 21-year-old allegedly broke into a west Eugene home in April. The homeowner, Oleta Nicholson, said Kowalchuck started beating her after a confrontation in the hallway.

      Kowalchuk faces several charges, including attempted aggravated murder, first-degree robbery and first-degree burglary,

      The District Attorney will make a decision on whether or not Kowalchuk can stand trial after the suspect undergoes an independent mental health evaluation.

      Kowalchuk is scheduled to face a judge on September 17.
