No firearm was discovered at the scene of DeWolf's apartment, which was orderly and where the valuables appeared to be untouched when officers arrived,said in a press release.

The cause of the injury wasn't immediately known after DeWolf's body was discovered and an autopsy was required to determine the cause of death, the release said.

The Washtenaw County Medical Examiner’s Office conducted the autopsy Thursday.

DeWolf was found dead in his apartment Wednesday in the Phi Rho Sigma fraternity house in the 200 block of North Ingalls Street. Police said DeWolf failed to arrive for a scheduled assignment at the VA Ann Arbor Healthcare System Wednesday morning.

The hospital sent a colleague to the home to check on him, and that person discovered DeWolf had died. Police were immediately called following that discovery.

A funeral is being planned, an Air Force official confirmed. The official couldn't release any further information.

The Schoolcraft, Mich. native was a 2010 graduate of Grand Valley State University, where he was a member of the Sigma Phi Epsilon. DeWolf had just completed his third year of medical school at the University of Michigan and was studying to be a surgeon. He was set to graduate with his class of 170 students on May 16, 2014.

DeWolf was a reserve officer in the Medical Services Corps of the United States Air Force serving as a medical student under the the military's Health Professions Scholarship Program (HPSP), according to officials.

University of Michigan President Mary Sue Coleman issued a statement Friday about DeWolf's death.

"We extend our deepest condolences to Paul’s family, friends and colleagues," Coleman's statement said. "He was working and training among a close, nurturing community of healers and I know they will help each other through this difficult time. They will need the support of the broader campus community in the weeks and months ahead, and we will provide it."
