A Cal Poly student who died while swimming at Montaña de Oro State Park was intoxicated with alcohol, marijuana and a psychedelic drug when he drowned.
Stefan James Wagner, 21, of Fresno was reported missing on June 20 after he dove beneath the water and disappeared in an area north of Spooner's Cove. His friends had tried to get him out of the water and called 911 about a swimmer in distress.
His body was found eight days later in the same area.
The cause of death was saltwater drowning due to multi-substance intoxication, according to lab results released Tuesday by the Coroner’s Unit of the San Luis Obispo County Sheriff's Office.
The results show Wagner had taken a designer drug called 2C-E, which is considered to have psychedelic properties.
“It can be compared to LSD in terms of hallucinatory effects,” Sheriff’s Office spokesman Tony Cipolla said.
Wagner, a third-year student majoring in biomedical engineering, played water polo in high school and was also a body-surfer who "loved the ocean,” his father, Fresno attorney Bryan Wagner, told The Tribune in June.
The case is still under investigation.
