Yes we do not know. But we do know he commited a fatal hit and run. Six months and 5 years probation pretty small when it is his 3rd offense.
Apparently no driver could have avoided the child. The child apparently darted out in front of the car in the middle of the street in the dark.
His charges are apparently unrelated to the death of the child.
He was charged solely with leaving the scene of an accident as far as I know.
Charges related to the child’s death were dropped after the investigation of the accident was finished.
