Calgary City Police are at the scene of what they call a homicide investigation on a rural property in the Gladys Ridge area.

They're searching the property in relation to the disappearance and suspected murder of 35- year- old Adam Stewart Young, who hasn't been seen or heard from since November 20th of last year.

Police say during the investigation they have determined a strong probability of foul play and are investigating the case as a murder.

Search warrants are being executed at the property as police look for evidence, and police expect to be there for several days.

Calgary Police are asking anyone with information on young's disappearance to call Calgary Police, or Crime Stoppers.

Neighbours in the area say they've been on the property since Tuesday, October 16, and spent the night there with large banks of lights illuminating the area.

Retired RCMP Officer, Rob Laird, lives close by.

"They're down the road from my house and the driveway's all blocked off, going into this residence. And there's probably eight or ten Calgary Police vehicles there. Many more on the inside, they've got a command centre set up. All night they had big pot lights set up on the property. With that turnout that would indicate there's something major going on."

The area falls under the jurisdiction of the High River RCMP, who say they have deferred to the Calgary Police Service in this investigation.

So far there's plenty of rumour and speculation, but Police have yet to comment on what exactly is happening on the property.
