TREMPEALEAU COUNTY, WI (WTAQ) - A Trempealeau County Middle School basketball coach says he will fight against allegations of child abuse while he was on the job.

A criminal complaint accuses 42 year old chemistry teacher Brady Ols0n of using dry ice to blow off a garbage can lid and cause water to shoot from a bottle during a team practice.

One or more players were burned with a 13 year old girl suffering a dime-sized burn mark on her inner thigh.

A published report quotes two other adult coaches who were at the practice as telling police they saw no misconduct.

Olson says he is in shock over the felony charge. He says having his name connected with child abuse is devastating.
