An autopsy conducted by the Clark County Coroner has ruled the cause of death of 34-year-old EDC Las Vegas attendee Michael Morse as acute MDMA and TFMPP toxicity, with environmental heat exposure as a second significant factor. TFMPP, or Trifluoromethylphenylpiperazine, is often sold as an MDMA alternative.
Billboard Dance has reached out to Insomniac Events for official comment.
Morse was the only reported fatality at the dance music festival's 2017 edition, which drew over 400,000 attendees over three days. According to authorities, 1,000 people sought medical treatment during the festival.
