Jessica Brown, OSBI public information director, said a toxicology report revealed that a large amount of methamphetamine was found in Brandy Buttery's system. A spokesperson for the medical examiner's office said the toxicology report was completed June 9, and the cause of death was listed as an accidental overdose of methamphetamine.
Brown said the OSBI is still following up leads on the drug aspect of the case.
According to the OSBI, Buttery, 23, and her boyfriend were visiting a friend's home just outside of Vian on March 19 when Buttery became ill and collapsed in the garage. Buttery was taken by ambulance to Sequoyah Memorial Hospital in Sallisaw, where she was pronounced dead.
The OSBI first listed the death as suspicious due to Buttery's age and the circumstances.
