Expert: Toxicology Tests Inconclusive in Myles Gray Beating Death

A forensic expert has informed a hearing that toxicology reports from 2015 provided limited conclusions regarding the behavior of Myles Gray during the incident that led to his death. Toxicologist Aaron Shapiro stated that alcohol, LSD, and psilocybin were not detected in Gray's samples. A strong indication of cannabis consumption was found, but the exact timing of use could not be determined, as the substance can remain in the body for weeks. Shapiro noted that while THC is psychoactive, it generally acts as a calming drug, with paranoia and hallucinations being extreme symptoms.

Initial findings also flagged the substance mitragynine, which can act as a stimulant or opioid, but subsequent confirmation tests revealed the quantity was below the reporting limit, meaning it was either present at a very low concentration or not at all. Further complicating the findings, a flag for a steroid, possibly trenbolone or testosterone, was noted in initial screenings. However, follow-up analysis could not reliably confirm or deny its presence, with Shapiro suggesting the instruments at the time may not have been capable of accurate detection. The hearing is reviewing the conduct of seven Vancouver police officers involved in Gray's death.
