An Ann Arbor police official confirmed investigators questioned multiple people last week about the death of Paul DeWolf but said police don’t believe those people are connected to the homicide.

“Subjects have been arrested on unrelated crimes and questioned, but as of today, the homicide investigation is still ongoing,” he said.
When asked if the people questioned in the case have been ruled out as possible suspects in the 25-year-old University of Michigan medical student’s death, Pfannes said, “We don’t believe at this point they have a connection.”
DeWolf was found dead on July 24 in his home at the Phi Rho Sigma medical fraternity, 220 N. Ingalls St. DeWolf died from a single gunshot wound to the neck, and police have said his basement room did not appear out of order, and no valuables appeared stolen.
Ann Arbor and University of Michigan police each have offered a $5,000 reward for information leading to an arrest and conviction in the case. U-M police and the United States Air Force are assisting AAPD with the investigation.
DeWolf was a reservist second lieutenant in the Air Force who was going to enter the service after he graduated from medical school. He was entering his final year at the University of Michigan after graduating from Grand Valley State University in 2010.
Anyone with information in this case is encouraged to call the Ann Arbor police anonymous tip line at 734-794-6939 or Crime Stoppers at -1800-SPEAK UP (773-2587).
