UFC Hall Of Famer, Stephan Bonnar, died from accidental fent overdose

The Clark County (Nev.) coroner’s office ruled Bonnar’s death accidental from “Fentanyl, Parafluorofentanyl and Mitragynine intoxication” in an email sent to MMA Fighting after a public records request following the UFC Hall of Famer’s death on Dec. 22 in Las Vegas. He was 45.

The coroner’s office declined to provide additional details on Bonnar’s death, citing medical privacy laws. Typically, the office determines a cause and manner of death within 90 days, but a spokesperson said Bonnar’s case took additional time due to additional testing performed during an autopsy.
