A 24-year-old California man who died at the Electric Daisy Carnival in Las Vegas last month overdosed on Ecstasy, the party drug linked to other fatalities at the annual festival in recent years, coroner's officials told the Los Angeles Times on Wednesday.
Montgomery Tsang of San Leandro collapsed and died outside the Las Vegas Motor Speedway shortly after 6 a.m. on June 21, according to a spokeswoman for the Clark County Coroner's Office.
Investigators determined he died of "acute MDMA toxicity," and also suffered from "cardiac enlargement," the spokeswoman said. Ecstasy is the common street name for MDMA.
She declined to comment further.
The Electric Daisy Carnival ballooned from a small Los Angeles-based festival to a national event in recent years, but the death of 15-year-old girl from an Ecstasy overdose in 2010 sparked the concert's relocation to Las Vegas.
The festival features DJs and electronic dance music, but the main draw is the scene itself. More than 400,000 people were expected at the festival this year, making it the biggest-attended multi-day music festival in the U.S.
Two people also died at the 2012 event in Las Vegas. The following year, the final day of the Electric Zoo festival in New York City was canceled after two people died at the event and four others were hospitalized.
At the time, city officials said they believed MDMA was linked to the incidents at the Electric Zoo event.
