BELLEFONTE, Pa. (CBS/AP) — A former Penn State University fraternity brother entered the first guilty plea in the death of a pledge who was fatally injured after a night of heavy drinking and hazing.

The Centre Daily Times reports 21-year-old Ryan Burke pleaded guilty Wednesday to all nine remaining charges he faced, including four misdemeanor counts of hazing.

Twenty-five other defendants face charges in the death of Timothy Piazza. The 19-year-old pledge drank a dangerous amount of alcohol and suffered fatal injuries in a series of falls during a party last year. Prosecutors say fraternity members did little or nothing to help him.

A forensic pathologist testified in March that Piazza might have been able to survive his injuries if fraternity members called for help sooner.

Burke was accused of giving Piazza a bottle of vodka at the party. He’ll be sentenced July 31.
