A university spokesman declined to comment on the report. But as the investigation continues, the financial fallout for the university is climbing. The estimated pricetag for the inquiry has reached $500,000. The school has already spent $292,000 for expenses such as sending students and administrators to funerals, tuition reimbursements for parents of the victims, security at the accident site and distribution of the books “When Bad Things Happen to Good People” and “The Bereaved Parent.” So far, though, the university hasn’t had to shell out for any legal settlements. In these litigious times, the lack of lawsuits is surprising. One apparent reason: Aggie loyalty. “[My son] was doing what he loved,” says the father of one victim.
