Two University of Wisconsin-La Crosse freshmen are accused of sexually assaulting another male student with a lint roller in a residence hall room late last month.

Casey Gudis, 18, of Ladysmith, Wis., and Brayden Wienke, 19, of Clear Lake, Wis., each were charged Wednesday in La Crosse County Circuit Court with first-degree sexual assault, Wienke as party to the crime.

The charges carry a maximum penalty of 40 years in prison and 20 years on extended supervision.

Wienke is accused of pinning the victim to the floor of a Sanford Hall room about 2:30 p.m. Sept. 27 while Gudis sodomized the man with the lint roller's handle, according to the complaint. The three students knew each other before the incident.

The 18-year-old victim told authorities the incident caused "unbearable pain."

"He stated he yelled for people to take it out at least twice as people in the room laughed at him," according to the complaint, which states three other students witnessed the assault.

Wienke told university police he threatened to jam an object into the victim earlier that afternoon after the victim tossed playing cards at him while he was taking an online exam, the complaint stated.
