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.
Burke was accused of giving Piazza a bottle of vodka at the party. He'll be sentenced July 31.
Defense attorney Philip Masorti says Burke is "anxious to make amends."
