More than seven years after the disappearance of Kelly Coleman of Clearview Township, the OPP have released a video on social media hoping to jog people's memory and bring this case to a resolution.
Police say the 34 year old was the mother of a teenage boy and in a long term relationship with a boyfriend Steve.
In conjunction with other evidence and circumstances, investigators are treating Coleman's disappearance as highly suspicious and they cannot rule out foul play.
OPP issued a press release in April 2012 asking for the public's assistance in locating Coleman who had not been seen or heard from since August 2011.
Her daily contact with a small group of friends and members of the medical community abruptly stopped.
On the video, Kelly's sister Lindsay Stubbs says she phoned her sister's boyfriend at the time and he assured her that she was fine and they had come to a point in their lives where he said they had parted ways and he had dropped her off in Barrie and he never heard from her again.
Stubbs says it doesn't make sense because Kelly would not have left without talking to her or her son.
Police say Kelly was last seen in the Barrie-area.
Investigators say those closest to Kelly did not report her missing until friends and family become involved and insisted police be contacted.
Police believe a text message Kelly's son received in January 2012 suggesting that it was his mother and she would be away for some time was not sent by Kelly.
They say the person who did send the text has answers to Kelly's whereabouts.
As part of the investigation, police searched a farmhouse property in Nottawa where Kelly and her boyfriend had been renting an apartment.
A billboard was also placed on Highway 26 between Collingwood and Wasaga Beach profiling details of the case as well as a $50,000 reward.
