GALESVILLE, Wis. -- A Gale-Ettrick-Trempealeau teacher and coach accused of burning seventh grade girls with dry ice has been put on paid administrative leave by the school district.

Brady Olson, a high school chemistry teacher at G-E-T, is charged with felony child abuse and disorderly conduct.

Olson allegedly put dry ice on the girl's legs in late January, leaving burn marks.

Olson says he was trying to make things fun during practice. He also used the ice to blow the top off a garbage can and caused water to shoot from a bottle.

The G-E-T School District did their own investigation in January, as did the Galesville Police Department and Trempealeau County Sheriff's Department. All three found some of the girls had pink marks on their knees, but no criminal activity had taken place.

G-E-T District Administrator David Grace tells News 8 Olson, who has taught in the district for 16 years, is on paid administrative leave and will not return until there is a resolution in court, or until information on the charges is clarified for school officials.

The dry ice demonstration is something Olson has done several times in the past without incident.

In a statement last week, Olson's attorney called the charges baseless. "The filing of charges in this situation, in the face of all the contrary evidence, is unwarranted and reckless," attorney James Birnbaum says.

"Mr. Olson intends to defend himself against these charges and anticipates that he will be exonerated from any criminal wrongdoing."

Olson is scheduled to appear in court March 27.
