At about 9:40 p.m. the first HFD ambulances reached the gate directly behind the main stage, only to be diverted to another area in response to a cardiac arrest. At least one of the district chiefs of those units was misdirected by security to a gate a from the medical tent, which wasted what he described as crucial minutes when patrons were likely dying. A HPD official advised several inquiring HFD officials on the radio that the show would soon end, but the concert continued. From 9:40 p.m. to 9:50 p.m. some HFD firefighters witnessed five patients at the medical tent whose hearts had stopped.
