Minnesota professor linked to series of bizarre incidents involving urine at university

Investigators determined professor responsible for urine found on a backpack, in trash cans and in water bottles

A former professor at Macalester College in the Minnesota city of St Paul is facing a felony charge for allegedly spilling his urine on a student's backpack while he still worked at the school, costing more than $2,000 in damages, according to a state criminal court document.

Paul Fischer, 55, is at the center of the bizarre, alleged workplace misconduct case that led to his being cited for first-degree damage to property - and linked to at least a half dozen such incidents involving urine at the liberal arts college over the course of a year.
