Two women who died over the weekend from apparent drug overdoses at the HARD Summer Music Festival were identified Monday as officials planned to launch a probe into how the event in Pomona was managed.
Tracy Nguyen, an 18-year-old from West Covina, and Katie Dix, 19, from Camarillo, were found unresponsive Saturday and hospitalized.
Nguyen died around 6 p.m. that day and Dix died about two hours later, according to the Los Angeles County Coroner's Office.
Nguyen, a business economics major at UCLA, was described as a "genuine and free-spirited girl" who was also a member of the school dance team.
"You've left so many wonderful memories for your friends and family ... you've changed the lives of many," an uncle posted on Facebook.
"My family loves her ... I love her. May you rest in peace," her brother posted.
Autopsies were expected to be performed on the teenagers in the coming week.
The sold-out two-day festival attracted some 65,000 people each day, making it the largest music festival in L.A. County, according to the Los Angeles Times.
A full probe into if the event was properly managed has been requested, Los Angeles County Supervisors Michael D. Antonovich and Hilda Solis told the Times on Sunday.
A GoFundMe.com account was set up for Nguyen's family.
Coronado High School opened its gates on Sunday for a gathering in remembrance of Dix who graduated in 2014.
