Ann Arbor Police have made three arrests connected to this summer's death of a University of Michigan Medical student. A press release says no other suspects are believed to be outstanding, and there does not appear to be any previous affiliation between the suspects and Paul DeWolf. The suspects also don't have any known connection with the University of Michigan or the U.S. Air Force. DeWolf was an Air Force Second Lieutenant. He was found dead in his apartment in July.
