Authorities in Las Vegas revealed Wednesday (July 9) that a 24-year-old California man who was found unresponsive in the parking lot of last month's Electric Daisy Carnival died of an ecstasy overdose.
According to Billboard, Clark County coroner's officials also ruled the death of San Leandro resident Montgomery Tsang an accident. Officials say his pre-existing condition, an enlarged heart, was also a factor.
Tsang was taken to the hospital and died the morning of June 21, after the first night of the electronic dance music festival.
Officials have not ruled on the causes of death for two other young people who were in town for the festival.
Anthony Anaya, 25, of Everett, Washington, was reported dead June 21 at the Vdara resort on the Las Vegas Strip. He attended the festival but Clark County Coroner Mike Murphy said it was unknown if his death was linked to the festivities.
Joey Saychack, 21, of Fresno, California, died at a hospital June 25.
He was taken to the hospital five days prior after being found unresponsive at a Las Vegas-area home. Saychack had rented the house with a group that was attending the festival.
Assistant Coroner John Fudenberg said Saychack never made it to the event.
Some 134,000 people attended the event at the Las Vegas Motor Speedway on each of its three nights.
Billboard also reports nearly 800 people were treated for medical conditions during the festival. Of those people, only 25 were taken to hospitals for treatment, police said.
Jennifer Forkish, spokesperson for event producer Insomniac, issued a statement afterward saying it was "deeply saddened" and asked everyone to help keep the event safe.
Organizers advertise a strict anti-drug policy. Several dozen people were arrested on felony drug charges.
Stay tuned for updated autopsy reports for Anaya and Saychack.
