MILWAUKEE — Milwaukee police are looking for the family of a baby boy who was found alone in a car seat in the middle of the night in a residential area.

Sgt. Sheronda Grant says investigators believe they have identified the child and his parents and are trying to locate them. The child is estimated to be between 4 and 6 months old. He was found unharmed at about 2:30 a.m. Tuesday about 7 miles (11 kilometers) north of downtown Milwaukee. Grant says the baby was found outside of a house but had no more information about who notified police. She says police will have an update later Tuesday.

The boy is white, weighs about 20 pounds (9 kilograms) and was wearing a gray Mickey Mouse T-shirt.
