According to a story in the UCLA newspaper:
http://www.dailybruin.ucla.edu/news/...s.asp?id=32575
Mike Ramsey, the Butte County district attorney who is prosecuting the Chico case, said the county filed hazing charges for the first time in county history because the charge seemed appropriate given the circumstances of the case.
Ramsey said the county was close to filing a hazing charge last year when a student suffering from hypothermia complained of having to sit in a pool of ice water for five hours, but he later became uncooperative in giving police information as to who was involved.
That same student is now one of the charged defendants in the Carrington case.
