A woman convicted in Alberta of helping her mother commit suicide is preparing to leave a psychiatric hospital in Phoenix, Ariz., for a homeless shelter. 

"Yes, it's really scary," said Linda McNall, 53. "I guess I'm going to have to go to a homeless shelter for awhile, before they find housing for me."

Linda McNall, 53, was returned to the U.S. nearly three weeks ago after eight months of custody in Alberta for her role in the suicide pact with her mother in which she alone survived.

Illness and poverty drove McNall and Shirley Vann, 79, to drive from their home in Arizona to Rock Lake, Alta., near Hinton, to take their lives in “the most beautiful place on earth.”

McNall is still suicidal, struggling with sadness and depression.

Before she was sent back to the U.S. on Jan. 8th with nothing but the clothes on her back, she told CBC News she still saw no future for herself.

While McNall is considered a suicide risk, she hopes she won’t try again.

“I want to try real hard to make my mom proud,” she said before leaving Edmonton.
