CHELSEA -- Police found a woman dead in the doorway of a Chelsea apartment Sunday morning, but they're not calling it a homicide.

A 911 call was placed at 223 W 16th St. around 8:32 a.m., authorities said. Officers found the woman, identified as 38-year-old Dr. Kiersten Cerveny of Manhasset, in the apartment building's vestibule.

Ceverny's body was found sprawled by the front door of the fifth-floor walk-up with bruises around her neck, police told PIX11.

"She was tall, and her head was hitting the door, and her legs were sprawled," witness Teal Camner said.

"I saw them working on her in the ambulance to resuscitate her," neighbor Nadia Hoyaken said. "I thought maybe [she had a] problem drinking."

EMS transported her to Lenox Hill Hospital Annex, where she was pronounced dead.

Cerveny's wedding to Dr. Andrew Cerveny Jr. at the Gramercy Park Hotel was featured in the New York Times in December 2009. She received her medical degree from Tulane University after graduating magna cum laude from Duke University and was the chief of dermatology at the Brooklyn Hospital Center for the past seven years. Her husband has a private dermatology practice in Massapequa.

She leaves behind three children, ages 1 to 7, a source close to the family told PIX11.

Police are hoping that nearby surveillance cameras captured images of the assailant, and many are wondering why this married mother of three from Manhasset was in the Chelsea apartment building early Sunday.

The Medical Examiner has not yet determined the cause of death.
