A Dolton village spokesman said a suspect in a vehicle going east on Sibley Boulevard fired a gun outside of the car.

She may have been caught in the crossfire when two groups started shooting at each other, but it was unclear who was the target.

Bowman lost control of her minivan – crashing it into a tree near Cottage Grove Avenue.

Witnesses said her four small children were seen running out of the car screaming for help, and saying their mom had been shot.

The kids were all unharmed physically, officials said.
