Chicago Tribune reporter Peter Nickeas with details on last night's crime in Chicago, including multiple Southside fires, a shooting in McKinley Park, and a stabbing in the Kennedy Park neighbordhood.

A security officer for the Aviation Department was stabbed to death by his son after the two got into an argument over cleaning the basement in their home in the Kennedy Park neighborhood on the Far South Side, authorities said.

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 told police he grabbed a knife around 2:45 a.m. Sunday and attacked his father as he sat on the couch, stabbing him in the face and the head, prosecutors said. The father tried to push his son away, but Mason Johnson threw his father to the floor, got on his back and put him in a choke hold.

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.
