​Collison was 58 years old when he was reported missing in September of 2009 and his body was discovered in April of this year. Passersby noticed partial human remains in a large irrigation ditch north of Winchester, Ont., and called police.

An autopsy confirmed death by foul play and DNA tests confirmed the identity of the victim.

Collison was last seen in 2009 outside the McCloskey Hotel in Chesterville. At the time he was living in a trailer on a farm just one road over from where the badly decomposed human remains were discovered.

When the body was discovered, the hotel's former owner told CBC News he knew Collison well.

"He just disappeared. Nobody seemed to know where he went. His relations didn't seem to know where he went. Nobody knew," Ivan Merkley said at the time.

Vern Williamson had said Collison was a handy man who fixed up houses and hung out at the hotel.

"He was a quiet fellow. He didn't bother anybody that I know of. But, like I say, he used to go over to Ivan's in the afternoon and have a couple of drinks," Williamson said.

Anyone with information on the case can call OPP at 613-534-2223 or 1-855-835-5677.
