The Ontario Provincial Police is offering a $50,000 reward for information that leads to an arrest in the 2016 disappearance of 43-year-old Karen "Karebear" Thompson of Toronto, a mother of four.
Police say foul play is suspected in her disappearance.
In July 2016, Thompson was reported missing by her daughter who last saw her in the area of Lakeshore Boulevard in Etobicoke.
While she had an address in Etobicoke, investigators said Thompson led a transient lifestyle and had ties to Dufferin County, Alliston, Scarborough, Oakville and the Hamilton area.
"My mom was a fighter and she was a strong woman. I know that she would fight for anyone who needed her help and she would do anything she could to help anyone in need. She has lots of friends and family that miss her very much and any information would bring lots of people closure," Thompson’s unidentified daughter said in a video released by the OPP on Thursday.
Thompson’s daughter said she was an involved and proud mother who was always teaching her life skills.
“We're asking those witnesses who have information about Karen's disappearance to contact the Karen Thompson tip line, the Orangeville OPP detachment or Crime Stoppers,” OPP Det. Insp. Chris Josiah said in the video.
Anyone with information can contact the OPP dedicated tip line at 1-844-677-9414, their local police service or Crime Stoppers at 1-800-222-8477 (TIPS).
