The purple paint on the door was covered up early Tuesday morning when ABC11 went to the center inside Harrelson Hall.
However, the university's student newspaper showed a photo of the vandalism before it was cleaned up Monday night.
The Technician reports that "fags burn" was painted on the door and "DIE" was written on a glass display case outside the center.
Campus police told the newspaper that the vandalism happened between 8:30 p.m. and 9 p.m. Monday.
They have no suspects at this time, but said the vandalism was being considered a hate incident.
Authorities are currently reviewing surveillance video in an effort to identify the person responsible.
