Medical examiners determined that a 20-year-old California woman who collapsed in a parking lot after the Electric Daisy Carnival in Las Vegas last month died from drug intoxication and high heat.
The Clark County coroner said Friday that Kenani Kaimuloa died of the combined effects of cocaine and the club drug Ecstasy, along with environmental heat stress. Her death was ruled an accident.
Kaimuloa's father, Dane Kaimuloa of Temecula, California, said at the time that he believed heat stroke and dehydration killed his daughter after three dusk-to-dawn nights at the June 17-20 music and entertainment festival.
He didn't immediately respond Friday to an email message, and his telephone rang unanswered.
High temperatures are common at the festival, which draws about 135,000 ticket-holders per night to the Las Vegas Motor Speedway.
