A 35-year-old media executive on a first date plunged to her death Thursday after the railing on her 17th-floor New York City balcony gave way, police said.

Jennifer Rosoff went outside for a cigarette around 12:50 a.m. when she either sat on the railing or leaned on it. Her date told her that she probably shouldn’t do it, and then moments later, she apparently fell backward and landed on construction scaffolding at the first floor, authorities said. Police spoke to the man and no foul play was suspected.

Emergency crews pronounced Rosoff dead at the scene. The medical examiner will determine a cause of death.

The gray brick high-rise building on Manhattan’s Upper East Side was built before World War II. Only the higher-floor corner apartments have balconies, and the city’s buildings department ordered residents to stay off them.

A photo of the corner balcony of the apartment where Rosoff lived shows the top two metal railings bent down in a V-shape. Buildings officials took part of the broken railing to examine how it could have given way and plan to determine whether the other balconies are structurally sound.

In 2010, after a 24-year-old social worker fell to his death when the railing gave way at his 24th-floor apartment terrace, the city conducted safety inspections on hundreds of residences. Tenants at 16 buildings were ordered to stay off their balconies because they were deemed unsafe.

Some 800 building owners failed to file mandatory inspection reports on the safety of their balconies and terraces, officials found. They are required to file every five years. For Rosoff’s building, the inspection report was last filed in February.
