RCMP in Elk Point, east of Edmonton, are investigating a suspicious death after a man was found naked in a farmer's field.

Police said  21-year-old Kyle John Martin of Marwayne was last seen at a home on Tuesday.

Wednesday morning, his naked body was found in a farmer’s field about two kilometres away from where he was last seen.

RCMP say there were no obvious signs of trauma to the body, but did note that a trail of clothing was found between the home and where Martin’s body was found.

“We've found some clothing over an area – and we're still looking trying to put the rest of it together.  That's why we're wondering if anybody had seen him, anybody had been talking to him - anybody thought this guy is kind of strange, but didn't call it into us.”

Sgt. Dave Casey said witnesses told police Martin appeared to be fine and sober when he left the house.

“Right now, yes, we treat it as suspicious – just because there's not an easy explanation to what happened,” said Casey.

An autopsy carried out in Edmonton on Thursday found nothing out of the ordinary, with no obvious signs of trauma and no indications of foul play.

Police are now awaiting toxicology results.
