"When he was examined, he went unconscious, they administered narcan. He was revived and the medical staff did notice a prick that was similar to a prick that you would get if somebody's trying to inject," said Finner on Saturday (November 6).
Houston Mayor Sylvester Turner listed the ages of the victims. "One is 14," he said.
The disaster unfolded at NRG Park at around 9 p.m. on Friday during the headline performance by Scott, a Grammy-nominated singer and producer, following an escalation of unruly behavior reported by members of the crowd and police.
As some in the sold-out audience of about 50,000 surged toward the stage, people began to fall unconscious, some apparently suffering cardiac arrest or other medical issues, officials told reporters outside the venue. Minutes later the chaos was declared a "mass casualty incident."
Earlier, Finner said police were aware of "rumors of people injecting some people with drugs" in the crowd, "so I want to check all that out."
