A gunman leaning out of a Cadillac sprayed another car with bullets early yesterday morning on the North Side, shattering the windshield and narrowly missing an 11-month-old girl strapped in a rear car seat.

Police from the North Side station responding to a report of multiple shots fired at 3:30 a.m. found numerous shell casings and bullet fragments at Perrysville and Wilson avenues.

While they were securing the scene, two women, with the baby in the back seat, pulled a bullet-damaged Lincoln into the police station parking lot to report being shot at in the 2200 block of Wilson.

The driver, 30, who is the mother of the child, said she and her passenger, 31, were on their way home from taking the baby to the hospital when the shooting happened.

They said a white Cadillac drove alongside their car on Wilson. As it slowly pulled ahead, a man in the back passenger seat opened fire with a semiautomatic.

Police spokeswoman Diane Richard said multiple slugs shattered the windshield of the Lincoln. One bullet passed through the windshield and exited the rear driver side door window, just missing the baby in her car seat.

"It was miraculous" that the girl wasn't hurt, Ms. Richard said.

Her mother, whom police would not identify, suffered an abrasion to her left cheek from the shattered windshield glass. The other woman wasn't injured.

Detectives didn't know if the women were targeted, the victims of mistaken identity or shot at randomly.
