The disappearance of an Edmonton woman has come to a tragic end. Police have confirmed the identity of human remains found in a Strathcona County subdivision in June. The remains have been identified as Shannon Collins.

But police are already describing their investigation as challenging because Collins wasn't reported missing until three months after the remains were discovered.

Randy Uytterhagen, lives in the Belvedere Heights neighbourhood where the grisly discovery was made on June 5. His neighbour's dog brought home a human skull and found scattered bones in the yard.

"Next thing we knew there was a whole crew of people out here and they went through the whole yard and they ended up finding more bones, " Uytterhagen told CTV News.

The identity of the remains was confirmed through dental records.

After Collins was reported missing, her sister set up a Facebook site in hopes of finding her. The site now includes notes of condolences for the 29-year-old mother.

Police say Collins led a high-risk lifestyle. RCMP are not releasing how or when Collins died.

Anyone who saw Shannon Collins between December 2007 and June 2008 is asked to contact Crime Stoppers.
