Autopsy: Ulele server accidentally drowned in Mango Lake

The autopsy showed Foster had a .098 milligrams-per-liter level of THC, or tetrahydrocannabinol, the intoxicating ingredient of marijuana. Pearson said that is a significant level.
“That indicates very recent use,” she said. “I would say she used marijuana within a half-hour or an hour before she died.”
