A retired Chicago police detective shot and killed his son after mistaking him for a burglar, authorities said.
Police said the body of 48-year-old Michael Griffin was found early Tuesday in the father's condominium on the 5300 block of North Delphia Avenue. He had been shot in the head.
The dead man's brother, Stephen Griffin, said the victim had been watching television with 77-year-old James Griffin when he went outside. Michael Griffin was shot when he re-entered the apartment.
Stephen Griffin said his father assumed Michael Griffin had gone to bed, adding his father's senses "aren't as sharp as they used to be."
Stephen Griffin said his brother was barred from his apartment due to non-payment of rent.
"I’m still freaking out about it. I have two sons of my own and I can't image how he must feel," Griffin said of his father, according to the Chicago Tribune.
Police have filed no charges against the father, who was hospitalized after complaining of chest pains.
