An Ohio teacher’s aide has been charged with raping a student with diminished mental capacity after the teen’s mother found them together at the boy’s home on a snow day.

“We received a call on Monday (Jan. 6) from the juvenile’s mother in reference to this woman being at her house with her son,” Sheriff Chris Hilton told McClatchy News.

Christin Coble, 45, was charged with rape after the January 6 incident. She made her first court appearance two days later and was given a $100,000 bond and ordered to have no contact with the 15-year-old victim.

The teen’s mother told WTVG that her child has the mental capacity of a 9-year-old.

“Our family is absolutely devastated over all of this,” she said about the alleged assault.

The superintendent of the Woodmore Local School District said Coble has been put on unpaid administrative leave.

Sandusky County authorities said they are still investigating the incident and are considering additional charges, including burglary for entering the home without permission.
