The search for a missing 51-year-old woman has so far come up empty.

Sheree Fertuck, from Saskatoon, has been missing since Dec. 7 when she was last seen leaving her family’s farm yard east of Kenaston, Sask.

Her semi-truck was found the next day at a gravel pit just off Highway 15, about 25 kilometres east of Kenaston, but RCMP officers and community residents have so far been unable to find her.

RCMP said late last week investigators were treating her disappearance as suspicious. Mounties encouraged residents in the area to check their property and outbuildings for anything out of the ordinary, like shoe or vehicle tracks.

Searchers have so far covered 35,000 acres by horseback, snowmobile, foot and vehicle.

Fertuck is described as five-foot-four and 250 pounds, with greying brown hair and blue eyes. She was last seen wearing grey sweat pants, a grey sweater and running shoes.

Anyone who saw Fertuck or her gravel truck — or any suspicious activity — between Dec. 7 and 8 in the Highway 15 area, east of Kenaston, is asked to contact Saskatoon RCMP at 306-975-5145 or Crime Stoppers at 1-800-222-8477.
