Joseph Nagel, 17, of Hanover pleaded guilty Friday to aggravated burglary, aggravated robbery, conspiracy to commit aggravated robbery, felonious assault, vandalism and two counts of kidnapping, The Cincinnati Enquirer reported. His girlfriend, Cheyenne Blanton, also 17, pleaded guilty in late July.

Both teens face as long as 59 years in prison when they are sentenced in Butler County Common Pleas Court; Blanton next Friday and Nagel in October.

Nagel and Blanton admitted breaking into Ashley Clark's house while she was alone, tying her up, shaving her head and eyebrows, putting her under a cold shower, making her walk in the snow and beating her. Prosecutors said the young woman was "humiliated, terrorized and tortured."

Sheila Clark, Ashley's mother, came home in the midst of the torture spree.

"We will live with this every single day of our lives," Clark said. "No human being should have to go through what my daughter went through that day."
