30 Injured After Deck Collapses at College Party in CT

At least 31 students were injured after a deck collapsed Saturday night during an off-campus house party near Trinity College in Hartford, Connecticut, police said.

"3rd floor collapsed on 2nd floor, which collapsed on 1st floor," tweeted Hartford Police Department Deputy Chief Brian Foley.

Foley later said at a press conference that the 3rd floor deck was very old and not structurally sound. It detached from the house and collapsed, he said.

Foley had said as many as 40 people may have be hurt. None of the injuries are serious, but he did tell ABC News there were "broken bones."

Trinity College said in an alert sent to students, "At this time the most serious injury reported is a broken arm."

The college later said in a statement, "We have confirmed that a total of 28 students were transported to five area hospitals. College staff went to the hospitals to be with the students and assist with getting in touch with the students' families and with providing transportation back to campus. At this time, the majority of the students have been treated and discharged by hospitals and the College will remain in direct contact with those students who remain in treatment."

The injured were transferred to various Connecticut hospitals, including Hartford Hospital and Saint Francis Hospital and Medical Center in Hartford, John Dempsey Hospital in Farmington, and Manchester Memorial Hospital in Manchester.

Hartford mayor Luke Bronin said in a statement, "There are dozens of injuries, but we are very lucky that there were no fatalities and no known critical injuries from what could have been a truly tragic incident."

Five people live in the house, which is owned by Trinity College, but managed by a private company, according to Foley.

Trinity College is a private liberal arts college and the second-oldest college in Connecticut after Yale University.
