The university has determined that the TCU chapter of Kappa Sigma fraternity was not involved in a Jan. 9 branding incident that reportedly occurred in Colorado, but individual students are still being investigated, a university official said Wednesday.

“The university has completed its investigation and found that the fraternity was not involved,” said Don Mills, vice chancellor for Student Affairs said.

The incident under investigation was reported by sophomore pre-business major Amon “Chance” Carter IV, a member of the fraternity. Carter reported that the incident occurred in Breckenridge, Colo., during a ski trip with several other members of the fraternity.

According to a Feb. 4 Breckenridge Police Department press release, the incident is being investigated as a criminal assault, although it has not been determined whether a crime was committed. Breckenridge police could not be reached for comment Wednesday.

Mills said that while the university had completed its investigation of the fraternity, an investigation about the involvement of between 18 to 24 individual students was ongoing. Mills said he could not speculate on the punishment of individual cases, but said that if students are found guilty, they could receive anything from a warning to a suspension. The investigation began more than three weeks ago, he said.

The university cannot release the names of the students whose involvement is under investigation, Mills said.
