No charges filed after floor collapse at Arapahoe County house party

Three people were injured when the first floor of a home partially collapsed during a party involving 100 to 150 juveniles, South Metro Fire Rescue said.

ARAPAHOE COUNTY, Colo. — Charges will not be filed in connection to a floor collapse that injured three people in a home during a birthday party Saturday night.

The Arapahoe County Sheriff's Office said it referred information to the 18th Judicial District Attorney's Office, which decided to not file criminal charges and closed the case.

South Metro Fire Rescue said crews were called just after 9:30 p.m. to the home on East Princeton Place, which is southeast of Aurora.

A portion of the first floor collapsed into the basement during the party involving 100 to 150 juveniles, according to the fire department.

One of the three victims was seriously injured, while the other two suffered minor injuries, the fire department said.

The sheriff's office said the homeowners were hosting a birthday party for their 18-year-old grandson. Deputies said at the time that it appeared to be a horrible accident, and they were not conducting a criminal investigation. 

People at the party said it got out of hand after the address of the home was shared on social media.

That's how 15-year-old Cass Henry and his brother, 17-year-old AJ Henry, found out about the party. 

"I think it just got leaked around a little bit so everyone thought it was just an open house," Cass said. "People started just showing up."

The brothers were two of the teenagers who fell through the first floor of the home. Cass said he ended up going to the hospital for a broken ankle.
