She yearned to learn more about her own roots and where her biological parents were from. At just three and a half months old, Linda Scott was adopted into a loving family and raised in Edmonton.

“We tried so hard to make her happy, to give her a good home, and she was never happy,” said Theresa Armstrong, Linda’s adoptive mother.

“There was always something missing in her life.”

Armstrong recalled Linda trying to learn more about her background when she was 18 years old.

“She filed a paper to see if she could find her biological mother,” said Armstrong, who never knew if Linda found anything out.

Raising her as her own, Armstrong said she still struggles with Linda's disappearance even though it's been 15 years.

“The last I heard from her, she was in Edmonton,” she said.

“She always used to call me at least once a month, no matter where she was, and when she didn’t call me I knew something was wrong.”

Both parents filed a missing person’s report.

Linda’s father, Harold Scott, remembers receiving a phone call from Linda in September 2000. She called from Vancouver's Downtown Eastside, asking for money, he said.

“I thought she'd be back,” he said.

Linda struggled with alcohol and drugs. The family says she was born with fetal alcohol spectrum disorder and had a difficult time in school.

Scott believes when someone is struggling with substance abuse, the police don't take their cases seriously.

He also believes Linda did not live too long after she disappeared.

“She told me that she had six months to live,” Scott explained.

He said according to Linda, doctors diagnosed her with cervical cancer and told her she had only six months to live. Linda was still living two years after she informed him of this news, he added.

“She always said that even when she was young that she wasn't going to live to be old,” said Armstrong.

“[It was] just really, really weird.”

Unsure whether Linda went missing from Edmonton or from Vancouver, Armstrong said she is often reminded of Linda’s mysterious disappearance.

“Every time there are human remains found, my heart's in my throat until I find out what [the] gender [is] for starters, and then until they've identified them.”

“I've spoken to the police officers occasionally over the past 15 years but not all that much,” says Armstrong, adding that her phone number hasn’t changed in over 30 years.

Armstrong said in the past, the Edmonton Police Service contacted her, as did the Vancouver police.

Armstrong believes Linda was killed by someone who fathered a child with her, a suspicion that she shared with police.

“I don't know if they could do anything else. I mean, if they can't find her, they can't find her,” said Armstrong.

“I know that logically, but I'm a mother and I want more. I want them to find her. I want them to find this person that hurt her.”

Armstrong supports a federal inquiry into missing and murdered indigenous women and girls.
