Edmonton police plead for information after remains identified as missing woman

Human remains found on the outskirts of Edmonton this winter have been identified as a 25-year-old woman who disappeared from the city last spring. 

In a statement Thursday, police said the circumstances of Teanna Lacoursiere's death are suspicious and they are appealing to the public for new information on the final days of her life.

Lacoursiere had been reported missing in April 2024. 

Police said Lacoursiere's remains were found in January, in a wooded area near Aurum Road and 17th Street, on the east of the city near the river valley. 

In April 2025, a year after her disappearance, a match from the National DNA Data Bank identified Lacoursiere as the deceased.

An autopsy was completed on the partial remains in late January but the cause and manner of her death has yet to be determined.

'Particularly complex'

At the time the remains were found, deep snow and difficult winter conditions prevented a full search of the surrounding area.

Police returned this spring to continue the search for evidence. 

Throughout April and May, EPS Missing Persons Unit co-ordinated multiple searches in the area where the remains were found, police said.

On May 26, with the assistance of Search and Rescue Alberta, a full grid search of the area was completed, police said.

"The search area was large and forested, which made this particularly complex," Staff Sgt. Kevin Harrison, with the EPS Historical Crimes Section, said in a statement. 

"Investigators planned to complete a full grid search prior to issuing a public notification in hopes of gathering important evidence that would advance the investigation." 

With that grid search complete, police said investigators are now appealing to the public for any information that might help shed some light on the case, and how Lacoursiere's remains ended up in the forest.

Anyone with information about Lacoursiere, particularly in the days leading up to her death, is asked to contact Edmonton police or Crime Stoppers. 

Lacoursiere was five feet one inches tall, 120 pounds, with blue eyes and brown hair. She had a tattoo across her chest and was known to change her hair colour. 

She was also known to go by the name "Mistey."
