A Fordham University student fell 140 feet from the top of the school's bell tower early Sunday, police said.
According to United States media reports, Ms Monfries slipped on her way up the tower's spiral staircase and was found by emergency services at about 3.17am.
"She couldn't breathe. She hit her head".
The infrastructure of Keating Hall made the rescue mission complex; medics were unable to maneuver the stretcher through the building's narrow stairway and had to use a rescue basket.
Ms Monfries' family rushed to her hospital bed and were accompanied by two priests, the Post reported.
At 6:49 p.m., Joseph M. McShane, S.J., announced to the Fordham community that Monfries had died.
Fordham University confirmed the incident and sent a letter to students.
Monfries, who was from Portland, Ore., was a senior at Rose Hill due to graduate in May.
The university said authorized school officials "have sometimes given tours of the tower, in part to satisfy students' curiosity about it, and reduce the likelihood that they would attempt to enter the structure without authorization".
"She was with a group of friends ..." The door to the tower is always locked, and only authorized staff can access the tower, the university said.
However the tower is off-limits to students and should have been locked, though there is now no information on whether the tower was unlocked or if the lock had been tampered with. "They were like, 'We're seniors, let's go!'" he said.
NBC reports that the iconic clock is "off limits" to students. "I think they were posting on Instagram when it happened". Organizers held a moment of silence for Monfries this morning.
