ANN ARBOR, Mich. (WXYZ/CNN) - Authorities are investigating the mysterious death of a University of Michigan medical student.
Paul DeWolf, 25, was found shot last week. Police are investigating it as a homicide, but so far they have no motive why someone would want to kill the popular aspiring surgeon.
DeWolf was an aspiring surgeon with a magnetic smile, living a full-life. He was high-school valedictorian, marathon runner and avid scuba-diver.
"Paul was probably the best person that I've ever met in my entire life. He really brought everyone that was with him up, myself included," said Jason Halterman.
Dead by a single gunshot wound, found in a pool of blood inside his bedroom at an off-campus fraternity house last Wednesday. His death sent shockwaves through the University of Michigan community, and stunning those who knew DeWolf well
"It's hard for me to believe that Paul would have any enemies. I don't know a single person that didn't like him," said Halterman.
Police believe DeWolf was killed in cold blood. Adding to the mystery, no weapons were found on the scene, and nothing stolen from DeWolf's room.
Authorities said they are "directing every available resource" to this investigation.
As officials hunt for DeWolf's killer, the University of Michigan is increasing police patrol and warning students to stay alert.
The vice-president of the university health system said, "Paul was a talented medical student who was dedicating his life to helping others."
The med student was also an active duty second lieutenant in the air force, planning to graduate in may and complete his residency while in the air force.
A young life taken, shrouded in mystery, no clues to what went terribly wrong.
DeWolf's parents released a statement saying he was "a brother, a son, a man of faith, and a good friend to everyone who had the pleasure of meeting him... Paul will be greatly missed but will always be cherished in our heart and minds."
