A Purdue University student pleaded guilty Thursday to murder in the fatal shooting and stabbing of a fellow Purdue University and West Bend Native Andrew Boldt in January. Special public defender Kirk Freeman says 23-year-old Cody Cousins did not seek a plea deal before he was convicted of murder. That leaves the door open to a consideration of Cousins' mental state when he stabbed-and-shot 21-year-old Andrew Boldt of West Bend on January 21st in an electrical engineering classroom on Purdue's main campus in West Lafayette Indiana. Boldt was serving as a teaching assistant at the time. Cousins admitted in court Thursday that he had gone to the campus with a handgun and a knife intending to kill Boldt, knowing where Boldt would be, and that he had used those weapons to kill him. A judge will decide the question of Cousins' mental state when he's sentenced on September 19th, and Freeman says a motive will also likely be disclosed. Freeman said he now intends to seek a verdict of guilty but mentally ill at the sentencing hearing, which is scheduled for September 19. If Cousins is found guilty but mentally ill, the Indiana Department of Correction would assign him to mental health treatment and he would serve the remainder of his sentence if he is pronounced cured.
