A Southern California raver who died after she attended June's Electric Daisy Carnival in Las Vegas succumbed to drug intoxication and overheating, coroner's officials.

Twenty-year-old Kenani Kaimuloa died as a result of “combined MDMA (ecstasy) and cocaine intoxication with other significant conditions, including environmental heat stress,” according to a report from the Clark County Office of the Coroner/Medical Examiner.

The young woman died Monday morning, after the last night of the festival. Reports indicated she collapsed with a temperature of 110 and that doctors initially put her on ice in an attempt to save her.

Family members — her father is an Iraq combat veteran — alleged that ambulances didn't reach her fast enough as a result of the three-day festival's notorious traffic jams.

The party, with more than 100,000 revelers a day, was held at night after daytime temperatures reached near-record levels.

Doctors originally attributed Kaimuloa's death to heatstroke, according to reports. 

Her father, Dane Kaimuloa, told the Las Vegas Review-Journal, “She was supposed to give me her Father's Day present” after returning to the family home in Temecula that Sunday.

EDC, as it's known, has seen about one patron death a year since it moved its flagship event to Las Vegas from Los Angeles in 2011.

It moved after the ecstasy death of a 15-year-old who had sneaked into EDC at the L.A. Coliseum sparked political uproar locally.

Following Kaimuloa's death, EDC's promoter, Insomniac, issued this statement:

We were shocked and saddened to learn that a young woman who had attended the festival passed away today, June 23, 2016. Our sincerest thoughts and condolences go out to the family and friends of the woman. While the cause of this tragedy has not yet been determined, we ask everyone to keep her loved ones in their prayers during their time of grieving.
