Cold case: Woman digs for answers after alleged killings of 3 boys

Glenna Mae Breckenridge says she saw her father murder three First Nations boys, who were later buried on the family farm. She eventually spoke to police, but there were no missing persons reports and her father denied her claims. 

With no bodies and no reports of missing people, the investigation went nowhere. But the memories lingered and Breckenridge still wanted answers.

"The pain of all of this, I couldn't tell you," Breckenridge says. "I've carried this for a very long time."

Decades later, CBC's Paul Hunter joined the Ontario woman as she travelled back to her old family farm and used new technology to try and find answers to old questions.
