24-year-old reveler died after collapsing last weekend.

Kimchi Truong collapsed on April 12, during the first leg of this year’s Coachella festival, and was pronounced dead at a local hospital on Thursday April 17.

Despite a statement from the promoters about possible drug overdose, the local Sheriff’s office said it was not clear yet whether or not drugs or alcohol were involved and that test results would not be available for up to six weeks.

Festival promoters Goldenvoice issued the following statement: “Last weekend, a festival attendee suffered an apparent drug overdose. The individual was seen by on-site medical staff and later transferred to JFK Memorial Hospital and later to Desert Regional Medical Center. We are saddened to learn the individual has died. We believe this to be an unfortunate but isolated incident. Our thoughts and condolences are with the family and friends.”

The California-based festival continues this weekend. [via The Hollywood Reporter]
