Stephan Bonner, a UFC Hall of Famer, has an established cause of death.
The first-season finalist of “The Ultimate Fighter,” Stephan Bonnar, passed away on December 22 in Las Vegas at the age of 45. Two days later, the UFC made the announcement, citing heart problems at work. Bonnar’s death, according to the Clark County (Nevada) coroner’s office, was really caused by an unintentional narcotics overdose.
A source from MMA Fighting stated that the coroner’s office declared Bonnar’s death to be unintentional and the result of “fentanyl, paraflurofentanyl, and mitragynine intoxication.” Medical privacy regulations prevented any more information from being shared.
In April 2005, Stephan Bonnar defeated Forrest Gryphon in a match that would go down in UFC history, earning him the title of “one of the most important fighters to ever compete in the octagon” according to UFC president Dana White. The MMA community was shocked by the news of Bonnar’s premature demise.
Fentanyl is a synthetic opioid that is so potent that it can be up to 50 times stronger than heroin and 100 times stronger than morphine, according to the U.S. Centres for Disease Control and Prevention. It is frequently discovered in fake tablets and combined with other substances like heroin, cocaine, and methamphetamine. It is practically impossible to tell if illicit drugs are tainted with fentanyl without testing.
According to Anne Milgram, administrator of the U.S. Drug Enforcement Agency, fentanyl is “the deadliest drug threat our country has ever faced.”
In February, the UFC held a Celebration of Life celebration for Stephan Bonnar at the UFC Apex in Las Vegas. Several speakers, including White, his legendary foe Gryphon, and friends and family, paid tribute to Bonnar.
