CHICAGO — A man is charged with stabbing an off-duty Chicago police officer, who is reportedly also his stepmother, while she was driving.
David Johnson, 21, surrendered to police just a few hours after the Friday morning attack in the South Shore neighborhood.
The 47-year-old woman was driving Johnson to a therapist for behavioral issues. He was recently diagnosed with schizophrenia.
Police say, when she stopped the car at 76th and Stony Island, Johnson stabbed her with a kitchen knife.
Her car then crashed into a school bus.
She was treated and released from the hospital on Sunday.
Johnson was denied bail.
