Are you Jeffrey Dupres? Alberta RCMP ask man missing for nearly 43 years to call them

A chief superintendent with the Mounties made a passionate plea Wednesday to a middle-aged man – missing since he was just three years old – to pick up the phone and call police.

A chief superintendent with the Mounties made a passionate plea Wednesday to a middle-aged man – missing since he was just three years old – to pick up the phone and call police.

The RCMP's Gary Graham attempted to speak directly to Jeffrey Dupres, who disappeared from his front yard in Slave Lake, Alta., on April 24, 1980.

"Here's the interesting thing: Maybe Jeffrey doesn't know that his family or the RCMP have never stopped trying to bring him home again," Graham told reporters.

"You've probably moved around a lot in your early life. Maybe you even feel like you're different from the rest of your family. If you believe that you're Jeff, please call the Slave Lake RCMP."

Last week, police shared an age-progressed rendering of what Dupres may look like now.

The image was paid for by the family and published in a CTV News Edmonton article in December, along with his mother's plea for help.

"It's absurd. I'm old, I'm handicapped. But he's still my kid, right?" Denise McKee said from her home in the Ottawa area.
