A college student’s newfound enthusiasm for his religious beliefs may have something to do with him being missing for three weeks, according to authorities in Rochester, Minn.

William “Harry” Hempy, 21, was on spring break and within weeks of graduating from the University of Illinois, but has not been heard from now since March 25, when he called his father to say he had “gone for a run” and would be late coming home for a family event.

Cellphone records indicate the call came from 55th Street NW. and W. River Road in Rochester, about 3 miles from the family’s home, police added.

In a statement released Wednesday, police said they’ve scrutinized “all possibilities and circumstances,” including probing Hempy’s “mind-set during the days, weeks and months leading up to his disappearance.”

Police said that friends and family revealed that Hempy experienced a rediscovery of his religious beliefs “and has been eager to share those beliefs with others.”

While stopping short of concluding that this religious re-engagement is behind Hempy’s disappreance, police are asking faith-based organizations who may have had contact with Hempy to call Rochester police investigator Anne Swenson at 1-507-328-6921.
