“Everybody was jumping, next thing you know, I’m jumping, I had my hands in the air and I can feel myself falling. Then I wake up, because I blacked out, and there [were] girls everywhere with blood all over their face,” Leroy Pearson told CBS affiliate WSPA-TV.

No deaths were reported, but police said some of the injured had broken bones. Authorities said an investigation into the collapse will continue this week.

Clemson University officials said they were notified of the situation early Sunday. The university’s president, Jim Clements, tweeted saying he’s monitoring the situation. “Our entire student support system will be available for any student impacted,” he said.

Property manager Tal Slann said he couldn’t comment on whether there was a limit to the number of people allowed in the clubhouse at a time. “I can tell you there was a party. I can tell you there was a floor collapse,” Slann told the Associated Press. “There were injuries. They were not life-threatening. Nobody was trapped.”
