Heather Adkins, charged with kidnapping and child endangering after she abandoned her son on a dark road in Colerain Township, could face up to 11 years in prison.
The 32-year-old mother was indicted on Friday, Hamilton County Prosecutor Joe Deters said.
Adkins is accused of abandoning her 5-year-old, non-verbal son on a dark road in the rain.
The boy was found by passing driver Ron Reese, who stopped to help.
