I kind of assumed you might be getting things from a fringe connection that might have had a shred of truth even if unlikely scenarios. But, for a high profile hire like this the interviewing school is not going to give one the names of the other candidates. You would not allow one candidate the opportunity to leak info about another candidate interviewing for a job. That could blow things up for that candidate and they may have been the one you wanted. Now sure, leaks happen all the time but generally those are somewhat controlled by the candidates. No way any reputable AD is sharing the names of other candidates.
