Ann Arbor police have arrested three people in connection to the fatal shooting of a University of Michigan medical student, Paul DeWolf, after more than three months of investigation. Police Chief John Seto said that the suspects, whose identities haven't been revealed yet, did not have any connection to the victim.

"After an intensive investigation, the Ann Arbor Police Department has made three arrests. No other suspects are believed to be outstanding," a statement read. "There does not appear to be any previous affiliation between the suspects and Paul DeWolf nor any connection with the University of Michigan or the U.S. Air Force," Mlive reports

The 25-year-old Air Force officer who was shot in the neck was a graduate of Grand Valley State University and was attending medical school on an Air Force scholarship. DeWolf was set to join the service after his graduation from U-M in May.

"The suspects have not yet been charged and detectives are continuing to gather evidence and build the case," the statement read. "More information will be released regarding the suspects' identities once they have been arraigned."

"Our focus continues to be the successful conclusion of this incident and respect for the DeWolf family," Seto told Battle Creek Enquirer.

DeWolf was remembered as a great runner, a brilliant student by his peers, a jokester, a loyal friend and a loving brother and son.

"It's overwhelming to know there's finally going to be a light at the end of this horrible, long, dark tunnel," Thom DeWolf, the victim's father told Mlive.  "The fact that ... it was nobody Paul knew, and no one we're going to know, that was huge. There's always the concern of who is it, who did it, is it someone we know?"

Mary Sue Coleman, the university president praised the efforts undertaken by the police.

"We are grateful for the determined work of the Ann Arbor Police Department and the University of Michigan Police Department in identifying and arresting suspects in this senseless act of violence," Coleman's statement said.

"We trust his family will draw comfort from this development, and that closure will ensue for them, our Medical School community and the broader Health System," the U-M Health System said in the statement.
