Two teenagers cried as they testified Wednesday at the trial of a B.C. woman charged after a teen died while her son was hosting a party at her house in 2008.

Shannon Raymond, 16, died following a party in July 2008 at the Maple Ridge home of Victoria Turley, who is standing trial for failing to provide the necessities of life.

Morgan Mays struggled and cried at times as she testified in B.C. Supreme Court on Wednesday, remembering how concerned she was about Raymond's welfare after she discovered her friend had taken ecstasy.

Mays testified she called the Turley home repeatedly that night, demanding to speak to Raymond. When her friend finally came on the line, Mays asked her if she was all right. She said Raymond made a retching sound but insisted she was OK.

Mays said, "All right. I love you."

Jordan Daye, who was also there that night, dabbed away tears as he recounted how he learned Raymond had taken ecstasy and appeared drunk.

He said that later at Turley's house, Raymond appeared unresponsive, needed help to lie down and then made loud groaning sounds from a bedroom. Daye told the court he left the party soon afterwards.

On Tuesday, the court heard from parent Veronica Geib who testified Raymond looked intoxicated when she dropped the teen off at Turley's home.

Geib said she was told Raymond had taken ecstasy, but she said she didn't report it.

The Crown alleges that Turley, 40, was the supervising adult in the house during her son's party and that she did not call for medical help for Raymond after she passed out.

Once paramedics did arrive, they could not revive the 16-year-old, the court was told.

If convicted, Turley faces up to five years in prison.
