TILLSONBURG, Ont. - Police are investigating after the body of an elderly woman was found outside an elementary school in Tillsonburg, Ont. Friday morning.

A Maple Lane Public School employee discovered the body around 6:45 a.m. ET, police said.

A superintendent at a seniors' apartment building beside the school said police were interviewing residents there about a woman who lived on the third floor and was unaccounted for.

Police said they would not release the woman's name until they notified next-of-kin, nor would they confirm where she lived.

The death didn't appear to be suspicious, said OPP Const. Stacey Culbert, adding that the bone-chilling weather gripping the region could be a factor.

It was -27 C with the windchill on Friday.

Clara Cosyns and Sydney Parvin, who live across from the school, woke up to flashing police lights around 7 a.m. Friday.

“They had the ambulance there and they were starting to move the body in,” Parvin said.

Cosyns wondered how long the woman was out in the bitter cold.

“I usually look out the window before I go to bed (but) last night I didn’t,” she said.

Another neighbour, Walter Zamecnik, 82, said there was a walker behind the police tape during the entire investigation.
