RCMP said Monday that the months-long investigation into the 2015 murder of a woman in her 20s had culminated in charges laid against four people.

Mackenzie Leah Harris, 22, was reported missing by a friend in August, 2015 – RCMP launched a search for the woman, which ended when a local resident found her remains in a wooded area in Calmar on August 3, 2015.

An autopsy determined Harris’ death was a homicide.

The four suspects were arrested Friday, March 4, and Saturday, March 6 in connection with her murder.

Now, Kyle Scott, 29, of Leduc, Dylan Bakke, 21, of Red Deer and Christopher Stein, 39, of Millet are all facing charges of second degree murder.

Bakke is also facing a charge of committing an indignity to a dead body.

A fourth individual has also been arrested and charged with second degree murder and committing an indignity to a body, but the individual was a youth at the time of the offence, and can’t be identified under the Youth Criminal Justice Act.

Scott is also facing another charge of attempted murder in connection to an unrelated matter dating back to 2014.

The accused are scheduled to appear in a Leduc courtroom Thursday, March 10.
