Coleman said some “traditional investigative techniques” led police to the area east of Calgary.

The body was found at around 6:45 p.m.

“I believe it’s just a field with some out buildings. I don’t believe there’s a residence there,” Coleman said of the scene. “It’s just a field east of town where there’s some type of storage bins, grain bins of some kind.”
