Myles Burton, 21, of Libertyville, Ill., who was on the basketball team at Elmhurst College, faces as much as five years in prison, the Chicago Tribune reported.
Investigators said Burton and two fellow basketball players committed the vandalism Dec. 8 and were identified from surveillance footage. Burton was arrested the next day and charged with a hate crime.
Burton, who was found guilty Tuesday in a one-day trial before a judge, is scheduled for a court appearance June 19. Lesser charges are pending against the other students.
"Targeting someone simply because they are different than you, will not be tolerated," DuPage County State's Attorney Robert B. Berlin said in a statement.
