WHITEHALL, Wis. (AP) -- A basketball coach at a Trempealeau County middle school says he plans to fight allegations of child abuse after some players were burned with dry ice.

Forty-two-year-old Brady Olson of Ettrick says he's in shock over the felony child-abuse charge. He says to have his name associated with child abuse is "devastating," and he expects to be fully exonerated.

A criminal complaint says the Gale-Ettrick-Trempealeau chemistry teacher used dry ice to blow off a garbage-can lid and cause water to shoot from a bottle during practice. He says he was trying to make practice fun

Prosecutors say one 13-year-old girl had a dime-size burn mark on her inner thigh.

A La Crosse Tribune report says two other adult coaches at practice told police they saw no misconduct.

GALESVILLE, Wis. -- A seventh-grade girls basketball coach is charged with a felony in Trempealeau County for allegedly burning his players with dry ice.

Brady Olson is also a high school chemistry teacher in the Gale-Ettrick-Trempealeau School District.

A criminal complaint says a player told police Olson put dry ice on the girls' knees and thighs, leaving burn marks in the incident January 20. The complaint says Olson also used dry ice to blow off a garbage can cover and cause water to shoot from a bottle during practice.

Olson said he was just trying to "make things fun for the girls." Olson is charged with felony child abuse and misdemeanor disorderly conduct.

District Administrator David Grace tells News 8 he was "surprised" when he was informed the charged were filed. Grace says an investigation was also conducted by the Galesville Police Department and Trempealeau County Sheriff's Department, which found there was no criminal activity in the alleged incident.

Grace says Olson was disciplined by the district after an internal review, but is currently teaching at G-E-T High School.

Sheriff Richard Anderson, Trempealeau County District Attorney Jeri Marsolek and Galesville Police Chief Paul Evenson were not available for comment Friday morning.

Olson is scheduled to make an appearance in court next week.
