Ottawa police have announced a $50,000 reward for information leading to an arrest and prosecution in the September death of Amy Paul.

Ottawa police released details of the reward Thursday, just over three months after Paul’s partially-clothed, decomposing body was found by a farmer in a rural south Ottawa hay field on Sept. 17.

Paul had disappeared from her home in the Vanier area earlier in the month. Relatives told CBC News she worked in the sex trade.

Ottawa police Staff Sgt. Bruce Pirt said the major crimes unit has interviewed dozens of witnesses, but have yet to gather key evidence needed for an arrest.

'Someone out there has a piece of information'

"I know there is someone out there that has a piece of information, and just maybe, this reward will prompt them to come forward," Pirt said.

"I believe that Amy Paul had a difficult, difficult life leading up to her death. She basically lived hand to mouth on the street."

Police are also consulting an entomologist to try to narrow down the time of Paul's death.

Anyone with information is asked to call the Ottawa police's major crimes unit at 613-236-1222, ext. 5493, or Crime Stoppers at 613-233-8477.
