The Durham Regional Police homicide unit is seeking help from students in the murder of a senior resident near the campus last year.
Ray Darby was found in his home on Maine Street just north of the intersection of Conlin and Ritson last June.
Police say he was found with obvious signs of trauma.
Police are hoping students living in the area may have heard or seen something.
Anyone with information is asked to contact Det. Mike Horrocks at 905-579-1520 ext. 5345. If students want to be anonymous they can call Crime Stoppers at 905-222-TIPS.
