A police officer has earned an award for undercover work on a murder case in Waterloo.

Police say the officer, who was from an outside agency, used his interpersonal skills and intuition to develop a relationship with and trust of three men suspected of killing Nadia Gehl.

Gehl was murdered at a bus stop near her Kitchener home in February 2009.

Eventually, Gehl's ex-husband and his accomplices confessed to the officer.

The officer testified for eight days during the murder trial last year.

All three accused were convicted of first-degree murder. 

The officer told CBC News he sees his involvement in the Gehl murder investigation as a small piece of a greater team effort. "Quite frankly, it's a collaboration," said the officer.

"It was not even remotely a solo effort, there is actually a real cast that was involved." said the officer. "If you don't have great leadership at the top, an opperation like this would collapse like a house of cards."

The award was presented on behalf of the citizens of Waterloo Region, the Waterloo Regional Police Service, and the Gehl family.

"I really can't say enough about Waterloo Regional Police. They're really the pinnacle of policing in Ontario."
