Edmonton Police Service officials said Thursday that the Homicide Section had taken over their investigation into the disappearance of a man in his 40s, who has been missing since the end of May.

Police said Homicide Section investigators had taken the lead on the investigation into the disappearance of Dwayne Demkiw, 42 – he’s been missing since Sunday, May 31, 2015.

“As we continue to investigate this file, investigators strongly believe that harm has come to Mr. Demkiw,” Det. Brian Robertson said in a press release. “We’re asking the public who live in acreages west of the city and property owners who live along the Highway 2 corridor to check their property for anything unusual and suspicious and report it to police.”

Demkiw was last seen leaving his place of work in the area of 149 Street and 128 Avenue at about 4 a.m. on May 31, 2015. He was reported missing later that day.

EPS said his vehicle was found in southeast Calgary (86 Avenue SE and Bonaventure Drive SE) by police in that city at about 11 a.m. that day.
