At two least adults knew that a B.C. teenager had taken ecstasy the night she died, a provincial Supreme Court judge was told Tuesday.

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

Parent Veronica Geib told the judge — who is hearing the case without a jury — that Raymond looked intoxicated when she dropped her off at Turley’s home.

Geib also said her daughter and a friend told her Raymond had taken two ecstasy pills, but Geib admitted she did not report the information to anyone.

The court was told that Turley also knew about the ecstasy.

Turley is heard telling police in a recorded interview later that she had been told Raymond had taken ecstasy and had been drinking.

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.

Raymond’s mother, Julie Raymond, said outside the court that the testimony has been painful to hear.

“The worst is yet to come and we know that,” Julie Raymond said. “Shannon didn’t die peacefully."

Raymond's sister, Danielle, said many more people also likely knew that Shannon had taken drugs.

"We're talking about errors not made by one individual, or two individuals, but probably about a dozen individuals over the course of the entire night," she said.

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