The attack was due to a school prank, in which a coach a student put a jockstrap on his head in the locker room student
A joke in the locker room of a high school caused a murder to take place over half a century later, a prosecutor revealed on Friday.
Carl Ericsson, 73, a resident of Watertown, who last month pleaded guilty but mentally incompetent without aggravating murder, was sentenced Friday to life imprisonment.
Kenneth Meyer, Lake County State’s Attorney, said Ericsson revealed that the attack was due to the incident, in which Johnson made Ericsson a jockstrap on his head in the locker room student. Johnson was then a star high school athletic trainer and student Ericsson.
Beth Ribstein, daughter of Johnson, said her father cut him off from Ericsson for years and explains why so long he held the grudge.
Ericsson pleaded not guilty to murder with malice in February and requested a jury trial. But Meyer and defense attorney Scott Bratland announced May 1 that it had agreed to a settlement. The charge of treachery was punishable by death if so requested by the prosecution.
Ericsson told the judge Vince Foley, that he rang the door-bell at the home of Johnson and then asked his former colleague to verify his identity before shooting with a .45 caliber pistol.
