The family of a 19-year-old who died after attending last year's Hard Summer festival in Pomona is suing the concert promoter.

The parents of Camarillo's Katie Dix have filed a suit against Beverly Hills–based Live Nation — as well as Los Angeles County, the Los Angeles County Fair Association, security guard provider Staff Pro Inc. and the city of Pomona — alleging that each “turned a blind eye to the known risks” of drugs at the event “in order to capitalize on teenagers and young adults who believed they were attending a safe party environment.”

The damages sought were not specified.

The suit says Dix took what she thought was ecstasy but was actually bath salts, leading to a deadly overdose. It alleges festival staffers who responded to Dix after she collapsed were not property trained and that their response was not “timely.”

A Live Nation spokeswoman declined comment , as did a spokeswoman from Hard Summer, which was purchased by the concert behemoth in 2012.

L.A. County coroner's officials concluded that Dix died as a result of “multiple drug intoxication” after she ingested MDMA, ethylone, a rare psychedelic drug sometimes found in bath salts, and alcohol.

Coroners investigators also said that Dix had a history of attention deficit/hyperactivity disorder (ADHD), allergies, asthma and elevated heart rate.

She was one of two Hard attendees who died following the DJ-driven rave at the Fairplex last August. Eighteen-year-old Tracy Nguyen of West Covina died of MDMA “intoxication,” according to the coroner's office.

Following the deaths, Hard agreed to raise the minimum age for entrance to its flagship Halloween festival to 21. No deaths were reported at that event. The L.A. County Board of Supervisors also threatened to ban raves from the taxpayer venues it runs, including the Fairplex, but it ultimately backed off.

Hard Summer's annual two-day party happens this weekend at the Auto Club Speedway in Fontana. The minimum age for attendance is 18.
