FLINT, MI -- Police say an hour passed before a mother realized her 19-month-old daughter had been shot while they were in the car together.

In a shooting that he called "bizarre," Michigan State Police Detective Robert Dunham said the girl's mother and her boyfriend were driving from a relative's home to the boyfriend's home in north Flint when suspects walked up to the car to rob them about 9 p.m. on Garland Street near 11th Avenue.

As the car fled, the suspect fired at the car.

It wasn't until the toddler was taken out of the vehicle at the Indian Hills mobile home park on Genesee Road between Stanley and Coldwater roads that the mother realized the young girl was shot in the leg.

"I don't know how a young child can get shot and not scream, yell or anything," Dunham said. "(The mother) said she never noticed any blood. She said she was moving her into the house, and that's when she notices she was bleeding."

The toddler was taken to Hurley Medical Center where she was initially listed in critical condition but was upgraded to serious Thursday.

Police did not release any suspect information. The child's name was not released. The incident remains under investigation.

"We got work to do to get to the bottom of this," said Dunham.

Anyone with information is asked to call Flint police at 810-237-6801 or CRIMESTOPPERS at 1-800-SPEAK-UP.
