CALMAR, Alta. -- Mounties are asking for tips to help them trace the last steps of a young woman found dead south of Edmonton.

RCMP say an autopsy has determined that 22-year-old Mackenzie Leah Harris of Camrose was the victim of a homicide.

Insp. Gibson Glavin says the woman was last heard from Saturday in Leduc and a friend reported her missing later that day.

Her body was discovered Monday in a wooded area in the nearby town of Calmar.

Glavin says Harris was last seen at the Aileen Faller Park in Leduc.

Investigators want to talk to anyone who may have seen or heard anything unusual at the park late Friday or early Saturday.

"That -- to this point in the investigation -- appears to be where we can last confirm her as being alive," Glavin said Wednesday.

He wouldn't reveal more details about the death, but RCMP have said the case is not related to four historical homicides they are investigating in the area.
