That work moves forward in conjunction with the B.C prosecution service.
McLeod and Schmegelsky were charged with the murder of Leonard Dyck, a University of British Columbia botany lecturer, and were also suspects in the deaths of American Chynna Deese and her Australian boyfriend Lucas Fowler. Police were urging residents near Manitoba's Nelson River to remain inside, lock their doors and report anything suspicious. "We kept the door locked during the day when we were in the house and same with the vehicles", McDonald said.
On July 21, the pair were spotted in Cold Lake, Alberta.
"But as a little bit of time passed, it kind of sunk in that we're never going to be able to ask them why they came here, what their role in the alleged crimes was and what a possible motive for that was".
Police initially treated McLeod and Schmegelsky as missing persons when their charred vehicle was found not far from Dyck's body.
"I don't have a timeline when they will be conducted, certainly as soon as we have that information were committed to providing it", she told Today.
Fowler, 23, the son of a high-ranking NSW police officer, and his girlfriend Deese, 24, were found shot dead and left in a ditch on the side of a highway on July 15. "All he ever said to me was how he wanted to kill me and ways he would do it".
Police appeared to be closing in the past few days after reporting finding items confirmed as belonging to the pair as well as a boat connected to them.
On July 19, Dyck, a University of British Columbia lecturer, was found dead near Lake Dease, two kilometres from the teens' burnt-out Dodge and nearly 500km from where Fowler and Deese's bodies were discovered.
The sighting led to a community lockdown and heavy search.
Alan Schmegelsky, the father of one of the men, has written a 132-page book titled "Red Flagged" that reveals his personal mental health issues, harassment convictions involving his ex-wife and the impacts these events had on his son Bryer.
Brittany Greenslade, Senior Reporter at Global News Winnipeg, said the hard terrain hampered the search. The terrain in Gillam has been described by survival experts as a hard place to survive for those who have no training.
".it was a search that could only be successful if we had strong public engagement and support".
