Texas police search for Ontario couple

Police in south Texas have released an alert about a couple from Fort Frances, Ont., who have not been heard from since mid-December.

Bruce and Linda Stewart, who are in their 60s, were last tracked to an RV Park in the town of Weslaco, Texas, but police said relatives have not had any contact with them for over a month.

J.P. Rodriguez, with the Weslaco police department, said police don't suspect foul play. However, he said, family members have noted the lack of communication from the couple is unusual.

“Miss Stewart was frequently updating her Facebook profile,” Rodriguez said. “According to relatives, they were frequently in contact with them. So it is kind of strange that they left our city and no one has been in contact with them since.”

Police involved since early January

Rodriguez said the couple may have relocated to the Yuma, Ariz., area.

Ann McCoy, a spokeswoman with the Rainy River District OPP, said police have been trying to locate the couple since Jan. 8.

“I've been actually working along with the investigating officer from this department here, from the OPP, to consult on a daily basis with the siblings and to let them know if we have any further information,” she said.

The Stewarts were last seen travelling in a 2006 grey, four-door pickup with Ontario licence plates. The pickup is pulling a trailer, and there should be a red canoe on top of the truck.

Anyone with information about the couple is asked to contact Rainy River District OPP at 1-888-310-1122.
