DALLAS — A former University of Oklahoma fraternity member who was shown in a video chanting a racial slur issued an apology Tuesday, as did the parents of a second student.

In a statement e-mailed by his father, Parker Rice said the incident that was caught on video was “likely was fueled by alcohol,” but “that’s not an excuse.”

“I am deeply sorry for what I did Saturday night,” Rice said. “It was wrong and reckless.”

Meanwhile, the parents of another student seen on the video, Levi Pettit, released a statement that said, “he made a horrible mistake, and will live with the consequences forever.”

Both are from Texas.

The chant referenced lynching and indicated black students would never be admitted to OU’s chapter of Sigma Alpha Epsilon.

OU President David Boren has severed ties with the fraternity. On Tuesday, he expelled the two students who appeared to be leading the chant but did not release their names. Boren said others involved would face discipline.
