This happened in Peoria in 2022, in the bathroom of a camp operated by Chicago-based First Ascent Climbing and Fitness.
An attorney at Clifford Law Offices says the 13-year-old boy accused in the case pleaded guilty to criminal charges.
On Monday, a jury found the camp was negligent in its lack of supervision, protocols, and communication in handling youngsters at the camp.
The 13-year-old in question was supposed to be under constant supervision.
ABC7 reached out to First Ascent Climbing and Fitness but did not immediately hear back.
