On Tuesday afternoon, two years after his unsolved murder, London police returned to the scene where Jonathan Zak's body was found.
The Forensic Identification Unit was set up looking for clues that could lead to the arrest of any suspects.
Zak's body was found two years ago Saturday on the walking path on the east end of St. Peter's Cemetery off Victoria Street.
London police say they are certain that someone in the city is aware of how and why Zak was shot to death.
Det. Gary Bezaire says "Leads are definitely still coming in and since day one, we've believed that people do know what happened that day, that evening, and we want people to come forward and tell us."
On Saturday, Zak's family and friends were at the same location, dedicating a bench in his name.
