Students from the University of North Texas were celebrating homecoming weekend and were at a party on the third floor of a student housing complex. But the floor gave way under the weight of the dozens of students gathered at the party.
Carly Carroll, an apartment resident told CBS affiliate WKRG-TV: "Its worse than you could possibly imagine because the sprinklers were on for two hours so not only was all of our stuff crushed, but its completely soaked with water".
Denton Fire Department Captain Brian Glenn said his rescue workers received a call for help about 2 a.m. Sunday morning.
Fox 4 reports the gathering was full of students from the University of North Texas who were dancing late into the evening.
"A medical triage was set up, but only minor injuries were reported", Denton Fire Marshal Brad Lahart said in a statement released Sunday.
Officials were forced to cut off water and power to the unit in which the collapse took place, the first- and second-floor apartments beneath it and nine other units in the building.
Local firefighters believe the floor collapsed because of too much jumping. They were at the police department reporting the party.
"They have parties quite a bit, nearly every weekend", Carley Carroll told NewsFix.
The Ridge at North Texas lists itself online as "a student-only community located in Denton, Texas, which serves the students of the University of North Texas, Texas Woman's University, and North Central Texas College". They're waiting to have structural engineers come in to verify that there's no structural damage that would cause a further building collapse.
