Three people were wounded when a gunman began shooting outside a home in Princeton Park on the South Side early Thursday, firing off at least 45 rounds.
The attack happened around 3 a.m. in the 9400 block of South Harvard Avenue, police said.
A 22-year-old man was hit in the chest as he was leaving out a back door of the home and was taken in critical condition to Christ Medical Center in Oak Lawn.
A man and a woman, 46 and 45, were inside the home and were grazed by bullets. They refused medical attention on the scene.
No one was in custody.
