WCSO Sheriff Michael Wilder told WFIE that the mother couldn’t find her son after waking up that morning.

“It’s a parent’s worst nightmare to find out that your child is dead,” WCSO Chief Deputy Paul Kruse told the station.

According to the station, the driver did not see the child in the road. Drugs and alcohol are not believed to have factored into the accident, the sheriff’s office added.
