The toxicology report of Cal Poly theatre arts sophomore Brett Olson — who was reported missing and later found dead in early September — revealed alcohol and cocaine in Olson’s system at the time of his of death.
The report, issued by Glen County Sheriff Larry Jones, lists Olson’s cause of death as asphyxiation due to drowning.
“As all findings are indicative of an accidental death and which this death will be classified as; the investigation into this extremely unfortunate case is closed,” the report states.
Olson first made headlines when word of him going missing following a Labor Day trip to the Sacramento river created a state-wide stir, prompting thousands to join in on the nearly week-long search. Olson’s friends and family soon took to Twitter, asking for people to post missing posters of him in their cities and towns. He was found dead on Sept. 9 at approximately 10:20 a.m.
Following his death, a candlelight vigil was held at Cal Poly on Sept. 17 to honor Olson’s memory. Vigils were also held in Olson’s hometown of Lafayette, Calif.
According to the report, Olson’s parents were notified yesterday of the findings. They could not be reached as of press time.
