The incident of a Texas Christian University student whose buttocks were branded on a fraternity ski trip to Breckenridge last month is under investigation by the university and officials with Kappa Sigma Fraternity.

Local authorities weren't made aware of the Jan. 8 incident in which the student suffered second- and third-degree burns after Greek symbols for his fraternity and a sorority were burned into his rump with a hot coat hanger.

“There's been no request to us to file any charges,” said Kim Green, spokeswoman for Breckenridge Police Department. “We're just trying to sort out the details and get more information.”

Amon G. “Chance” Carter IV will need plastic surgery to repair the damage. He's the great-grandson of Amon G. Carter, Sr., a Fort Worth civic leader and founder of the Fort Worth Star-Telegram, according a report in the Star-Telegram.

Carter and his family say they're considering criminal charges or a lawsuit against people involved. Up to 18 people are believed to have witnessed the incident, according to the Star-Telegram.
