RAPID CITY, S.D. (AP) - An autopsy performed on a Sturgis mixed martial arts fighter says he died of a subdural hemorrhage from blunt force trauma to the head related to an injury from a week earlier.
The family of 26-year-old Dustin Jenson says he suffered a seizure after a May 18 fight at the Rushmore Plaza Civic Center. Doctors later did surgery to relieve pressure on Jenson's brain, but he was declared brain dead on May 24 and taken off life support the next day.
Rapid City police say in a release that although that timeline is consistent with the organized fight, there's no conclusive evidence the injury was sustained in the event.
Mixed martial arts fighters use a variety of techniques, borrowing from boxing, wrestling and various forms of martial arts.
