Police investigate 3 theories in Mackenzie Trottier's disappearance

Mackenzie Trottier disappeared two years ago in Saskatoon at the age of 22.

SASKATOON – Saskatoon Police Service say they are investigating three possibilities in the disappearance of Mackenzie Trottier.

Mackenzie disappeared two years ago in Saskatoon at the age of 22. Her family last saw her when she left their home in the 300 block of Trent Crescent of Saskatoon’s College Park East neighbourhood on Dec. 21, 2020.

“There are several theories regarding Mackenzie’s disappearance,” Joshua Grella, coordinator/public relations for Saskatoon Police Service told Monday in an email. “All theories continue to be examined until such time that evidence can either prove or disprove a theory.”

SPS hasn’t announced they are investigating Mackenzie’s disappearance as a homicide but that is being considered.

“Homicide is one theory but the investigative scope is not limited to only that,” said Grella.  "I’m limited in the details that I can share as this is an ongoing investigation.

“Mackenzie continues to be an active missing person with the Saskatoon Police Service," he added.

Mackenzie last accessed her cell phone Dec. 24, 2020, and didn’t show up as planned for Christmas with her family.  

“The determination of homicide would involve more than cell phone and banking records, however, those would certainly be considered in any missing persons investigation and have been in Mackenzie’s,” said Grella. “In brief, the disappearance of Mackenzie Trottier has not been narrowed enough to only consider homicide as a theory.”

In such files, Grella said that the missing person might be: Missing by choice and doesn’t want to be found; taken by someone either known or unknown to them, which could involve human trafficking; or murdered and disposed of, resulting in a homicide.

Mackenzie being the victim of human trafficking is a theory, said Grella, but he added, “evidence does not suggest it as probable.”

Grella said that SPS continues to receive tips but the investigators don’t have any new leads.

In December 2021, Calgary Police Service issued a media release saying they had received information that a person matching Mackenzie’s description was seen multiple times in downtown Calgary. Grella said this tip was “thoroughly investigated and confirmed to be unfounded.”

In February 2021, SPS Major Crime Section released photos and a sketch of a male they believed may have information about Mackenzie’s disappearance.  The man is described as approximately 5-foot-3 inches. 

“The video was from a convenience store located in the 1400 – 1600 blocks of Idylwyld Drive in Saskatoon,” Grella told

Mackenzie is 5-feet and 145 pounds. She has a fair complexion, blonde, medium length hair, and green eyes. She has broken front teeth and a tattoo on her right ankle. Saskatoon Police Service say that Mackenzie was in a vulnerable state when she went missing. 

If you have any information on the male in the sketch and photo, or the location of Mackenzie Trottier, please contact the SPS at 306-975-8300, or Crime Stoppers at 1-800-222-8477, or online.
