The chair of a committee set up to deal with Unofficial Saint Patrick’s Day at the University of Illinois Urbana campus says he cannot be certain that the death of a student was definitely due to the unsanctioned event. Dean of Students Kenneth Ballom says the very nature of 'Unofficial' as a de-centralized, unorganized event makes it hard to be sure that the fatal fall of Jonathan Morales from a Champaign apartment balcony was truly a part of it.
