Police probe death of woman found in Manhattan building

A 38-year-old doctor from Long Island was found dead with bruising around her neck in the doorway of a Chelsea apartment building Sunday morning, law-enforcement sources said.

An unidentified man spotted an unconscious Cerveny at about 8:30 a.m. Sunday in the vestibule of a five-story walk-up building on West 16th Street in the Chelsea neighborhood, investigators said.

Brie Bobalec, who is also a tenant in the building, told the New York Post that just last week a stranger was banging on her apartment door and repeatedly ringing the doorbell after midnight. A medical examiner is now investigating the cause of her death. Police identified the woman as 38-year-old Kiersten Cerveny of Manhasset, but have no further information on how she died.

Investigators have video from inside the building showing two men carrying Cerveny down the stairs, a police source said.

One of the men has been questioned and released, the Post reported.

No arrests have been made, but police are now searching for the man who flagged down the ambulance.

Detectives from the 10th Precinct spoke to her dermatologist husband but do not believe he is involved in her death, Sanchez reported. She received her medical degree from Tulane University and was the chief of dermatology at the Brooklyn Hospital Center for the past seven years.
