Joe Roderick claims two thieves were let into his East Vancouver apartment building in late August, broke into his suite and stole his valuable coin collection in a targeted heist.
Now, fed up with what he believes is a slow-paced police investigation, Roderick has posted online surveillance video and photos of the alleged suspects.
He said he's not concerned about potentially identifying people who have not been convicted of a crime or being charged with defamation.
"There's no question that these men are suspects and nothing more. But in order to find out more, we need to identify who they are," he said.
"I am going to identify these men, if I can."
A private citizen could be held responsible for any actions that defame another person if those allegations are not proven.
David Jones, a former Vancouver Police inspector, says private citizens should not post not take it upon themselves to post such content themselves.
"I think the justice system ought to work in a manner in which people feel confidence in the police, that they can present this information to them, that the police will follow up."
Vancouver Police say no arrests have been made and they're still investigating, but cannot say a person has committed a crime unless Crown prosecutors are satisfied.
