Prosecutors said Mason Johnson, 24, admitted to killing his father, Kenneth Johnson, 48, because "he was angry with [the elder Johnson] for nagging him about cleaning the basement," prosecutors said in court today.
Mason Johnson dropped the knife during the struggle and Kenneth Johnson was able to grab it and stab his son, prosecutors said. His son got the knife back and began stabbing the father again, prosecutors said.
Someone inside the home saw the struggle and called police. When officers responded to the home in the 11400 block of South Rockwell Avenue, the son was still holding the knife and was shocked by a Taser.
Kenneth Johnson was pronounced dead at 3:50 a.m. Sunday at Advocate Christ Medical Center in Oak Lawn, according to the Cook County medical examiner’s office.
Prosecutors said Kenneth Johnson was a lieutenant with the Aviation Department's security force. He was also a shift supervisor, according to Gregg Cunningham, a spokesman for the department. Johnson worked out of O'Hare International Airport, he said.
Mason Johnson was charged with first-degree murder and was ordered held without bail.
