A 57-year-old woman died after plummeting from a building on the corner of University Place and 13th Street, the police said.

The fire department received reports of a jumper in cardiac arrest around 11:50 a.m.

Isaac Samuels Bruton, 45, was working nearby on a film shoot when he heard that a woman jumped out of a window. “A couple of my co-workers were going to lunch and said they saw her coming down,” he said.

Shearn Franklin, 20, an employee of Vive la Crêpe, located diagonally across the street, said he was facing a customer when he heard a “loud pop” from the shop’s open windows. “I thought it was someone dropping a box,” he said. He walked outside the store with his manager and saw a person lying lifeless on the pavement.

By noon, there were about a dozen police officers surveying the scene. On the sidewalk outside of Vapiano’s, the eatery on the ground floor of 113 University Place, the woman was covered with a white sheet. A gray sneaker lay next to the sheet, with heavy yellow tapestry keeping it in place.

Police officers said they were in the preliminary stages of the investigating the incident, which had not been officially ruled a suicide.
