FONTANA, Calif. (KABC) --The deaths of three people at the HARD Summer Music Festival in Fontana back in late July have been ruled ecstasy overdoses, according to the coroner's report.
The San Bernardino County Sheriff-Coroner Department's report stated that 22-year-old Roxanne Ngo of Chino Hills, 22-year-old Derek Lee of San Francisco, and 21-year-old Alyssa Dominguez of San Diego, died from methylenedioxymethamphetamine toxicity.
HARD Summer Music Festival was held at the Auto Club Speedway from July 30 to July 31 and was headlined by Ice Cube, Major Lazer and dozens of performers.
More than 146,000 people attended the three-day festival, according to organizers.
