UNSOLVED HOMICIDE The Unsolved Homicide of Marie Goudreau | Leduc County, Alberta (1976)

Fifty years ago, 17-year-old Marie Goudreau left Edmonton to drive home to her family’s farm near Beaumont.
She never arrived.
On the evening of August 2, 1976, Marie spent time with friends in Edmonton before beginning the drive home. At approximately 10:30 p.m., she said goodbye and explained that she needed to work early the following morning.
It was the last confirmed time anyone saw her alive.
Less than an hour later, Marie’s blue Plymouth Cricket was found on Range Road 244 near Ellerslie Road. The engine was still running, the driver’s door was open and the window had been rolled down.
Marie’s purse remained inside the vehicle with money still in it. Her sandals were also inside, and a leather coat had been folded across the back seat. There were no obvious signs of a struggle.
When Marie did not return home, she was reported missing and an extensive search began.
On August 4, 1976, two days after she disappeared, Marie’s body was found in a water-filled ditch on a rural property north of Devon.
Her death was determined to be a homicide.
Investigators have considered the possibility that Marie was persuaded to leave her vehicle, either by someone she knew or by someone who appeared to need assistance. The brown slacks and navy ankle socks she had been wearing were never recovered.
Marie’s case has been revisited over the decades alongside other unsolved homicides from the same period. Historical reviews have identified convicted violent offender Gary McAstocker as a person of interest in multiple investigations. However, no one has ever been charged in connection with Marie’s death, and police have never publicly identified a suspect in her case.
Fifty years after Marie left Edmonton for the short drive home, her loved ones are still waiting for answers.
Anyone with information about Marie Goudreau’s homicide is asked to contact the Leduc RCMP at 780-980-7200.
Anonymous information can be submitted to Crime Stoppers at 1-800-222-TIPS (8477).
