Barrier had no dead muscles but had heart disease. In medical terms, he died from a heart disease combined with cocaine use, Murphy said, clarifying Simms’ findings."Not satisfied with the findings of the Clark County Coroner, Barrier’s family hired independent pathologist Dr. Rexene Worrell to perform an autopsy.  Barrier’s family was promised photographs, video, audio, and notes documenting the examination upon completion of the autopsy.  Once completed, however, Worrell declined to provide the family with the findings, saying, “I need to hold on to the file in case it goes to court.”  As of 2018, 10 years after the independent autopsy, the information obtained by Worrell concerning Barrier’s body had yet to be released to the family.
