Overnight, rumors of a death at HARD Summer before Flying Lotus took the stage were dribbling throughout the crowds and online. While there is no official cause of death, word is that the patron, a young male, passed away due to "cardiac distress" at the hospital. FlyLo even commented on the situation via Twitter:

SPIN reported that they'd seen the situation unfold before FlyLo's set, saying that they'd heard sirens and "followed the emergency vehicles to the scene, where police were making room as medics performed CPR on the man, who'd apparently been lying near the edge of the field." He was unable to be resuscitated and was taken to the hospital on a gurney. Live Nation, who purchased HARD Events last year, offered up the following statement:

During Saturday evening's event held at Los Angeles State Historic Park, a patron experienced cardiac distress and sadly passed away at the hospital. Our thoughts and prayers go out to his family and friends.

Our guests' safety and well being is of paramount importance at every Live Nation event. We have skilled EMT's, police, and security staff deployed on site to respond to any emergency situation and last night members of this emergency team were with this patron and administering CPR within two minutes of notification. We work closely with local health and safety authorities to plan for emergencies and set the appropriate staffing levels for each event.

For more information please contact LAC+USC Medical Center.

We'll keep you posted on developments to this story.

UPDATE The LA Weekly is reporting that an official says that the young male was transported to L.A. County-USC Medical Center in "grave condition," and that the cause of death was suspected to be an overdose.
