 Dix collapsed after ingesting a drug she thought to be "pure 'Molly'" at the event, the lawsuit said, referring to another name for the drug Ecstasy. The suit alleges that the rave was overcrowded and understaffed and that the medical response to Dix was delayed by half an hour, during which she fell into cardiac arrest. 

 19-year-old Katie Rebecca Dix died of suspected overdoses while attending the HARD Summer Music Festival in Pomona on Saturday, Aug. 1, 2015. 
 
 A couple whose 19-year-old daughter died of a drug overdose during a rave at the Los Angeles County fairgrounds in Pomona last summer are suing the promoters and several other defendants, alleging her death could have been prevented. 
 
 The parents of Katie Dix of Camarillo are seeking unspecified damages on wrongful death, negligence, premises liability and public nuisance allegations. 
 
 The suit names as defendants Live Nation Entertainment Inc., Los Angeles County, the Los Angeles County Fair Association, security agency Staff Pro Inc. and the city of Pomona. 
 
 Representatives for Live Nation and the Fair Association did not immediately reply to requests for comment. 
 
 According to the lawsuit brought on behalf of Mark and Pamela Dix, their daughter was about to enter her second year of college when she went to the first day of Hard Summer Music Festival last Aug. 1. 
 
 The suit maintains that the defendants knew or should that the drug Ecstasy is "commonly ingested at raves" and that it would be distributed and consumed at Hard Fest. 
 
 The defendants “turned a blind eye to the known risks in order to capitalize on teenagers and young adults who believed they were attending a safe party environment” sanctioned by the city of Pomona and Los Angeles County, the suit alleges. The rave fans also believed there were would be sufficient security and emergency personnel, according to the suit. 
 
 Katie Dix consumed what she thought was pure Ecstasy, often called “Molly,” but she instead consumed high levels of so-called “bath salts” that caused her to show common signs of a drug overdose, according to the complaint. 
 
 Although there were 65,000 in attendance, there were only four medical stations and those who treated the young woman -- who was found unresponsive -- were not properly trained, the suit states. 
 
 She was later taken to Pomona Valley Medical Center, where she died. 
 
 The plaintiffs allege that "had medical treatment at Hard Fest been timely and proper, Katie Dix would have been saved." 
 
 Another festival attendee, 18-year-old UCLA student Tracy Nguyen, also overdosed on Ecstasy and died before the plaintiffs' daughter ingested the drug, the suit states. 
 
 Some 50 others present at the festival also experienced drug-induced seizures and comas, “overwhelming emergency rooms with teenagers and young adults,” the suit states.

– Katie Dix, the Cal State Channel Islands college student who died of an overdose at a rave at the Los Angeles County fairgrounds last August, allegedly went without medical attention for half an hour after collapsing. She'd suffered a cardiac arrest by the time she arrived at the Pomona Valley Hospital Medical Center. Last Friday her parents filed a lawsuit against the Los Angeles County Fair Assn., the city of Pomona, the county, and event host Live Nation for negligence, reports the Los Angeles Times. The suit alleges that the defendants "breached their duties to protect" those attending the Hard Summer Music Festival from people distributing illicit drugs and that the rave was overcrowded and understaffed. Dix's parents contend their "lively and vivacious" rising sophomore would have been saved "had medical treatment ... been timely and proper." Dix apparently thought she'd taken "pure Molly," or ecstasy, but had consumed "bath salts," NBC Los Angeles reports by way of the suit. The suit says there were four medical stations to service the festival's 65,000 attendees, and alleges that those who responded to Dix didn't have proper training. She was one of two young women to die from an overdose at the rave on Aug. 1, with 49 people total taken by ambulance to seven different emergency rooms over the fest's two days. Long before the Dix lawsuit was filed, the Times reports LA County Supervisor Michael D. Antonovich called the rave operators "irresponsible" and said that "no one should have to lose their life by attending a music event at one of our facilities."
