A dead Longhorn steer with its stomach cut open was found in the yard of an Oklahoma State fraternity on Friday morning, and a criminal investigation has begun.

Stillwater police spokesperson TJ Low told The Oklahoman officers were informed of the dead animal’s presence just before 7 a.m. Friday. He said it has since been removed and police are investigating how long it has been dead and where it may have come from.

The dead animal was found in the FarmHouse fraternity’s front yard. The animal’s stomach was cut open, and the words “(expletive) FH” were written on its side, per photos taken by staff of the OSU student newspaper, The O’Colly. Due to the nature of those specific photos, they were not displayed in this post.

However, CBS 11 News Reporter J.D. Miles posted the following image:

“Oklahoma State University is appalled at the disturbing display of animal cruelty that occurred overnight at an off-campus location near a fraternity house,” the university said in a statement, per The Oklahoman.

Texas and Oklahoma State meet Saturday in the Big 12 Championship Game. The seventh-ranked and SEC-bound Longhorns won the inaugural Big 12 championship game in 1996, and now play their last one. The 11-1 Longhorns last won the Big 12 title game in 2009 to make the BCS national championship game, and their only other Big 12 title was in 2005 when they were the league’s last national champion. Oklahoma State won seven of its last eight games to get into the Big 12 title game for the second time in three seasons.
