NEW YORK -- New details are emerging Monday into the events leading up to the death of a Long Island doctor who was found in the doorway of a Chelsea apartment building early Sunday morning.
Kiersten Cerveny, 38, of Manhasset, had a seemingly picture-perfect life. She was married with children, they lived in a house in Manhasset and she had a dermatology practice in Williston Park. But that all changed after police said she had a night out on the town in Manhattan before she was found unresponsive hours later. Her autopsy came back inconclusive pending further studies, including the toxicology, leaving detectives to continue to piece together the details to determine what exactly happened to her. However, sources close to the investigation say that her death does not seem to be a criminal act. It's believed that she died of a drug overdose.
Here's a timeline of what we know so far about her night, according to NYPD investigators:
6:30 p.m. Saturday
Police said Cerveny went out with friends to a hotel.
Later Saturday night (time not released)
Cerveny and her friends moved to a bar on the Lower East Side. Friends told detectives there was alcohol and cocaine use.
2 a.m. Sunday
Cerveny met up at the bar with a 51-year-old man she knew from Facebook who produces TV shows.
Between 3 a.m. and 4 a.m. Sunday
Cerveny left her friends, getting into a cab with the 51-year-old man.
4:25 a.m. Sunday
Cerveny and the 51-year-old man arrive at the cab driver's home on West 16th Street between 7th Avenue and 8th Avenue. Surveillance video shows them walking into the building.
Later in the morning (time not released)
Cerveny becomes incapacitated and was carried back down the stairs by the two men. The men place her in the lobby of the building.
8:32 a.m. Sunday
Police said the 51-year-old man called 911 and stated there was an unconscious woman in the lobby at 221 West 16th Street.
Police arrived and were directed to the correct address, 223 West 16th Street. The 911 caller was not there, surveillance cameras caught both him and the taxi driver walking away from the building before officers arrived.
The victim was alive but unresponsive, police said.
A delivery worker told Eyewitness News he saw a man flagging down the ambulance to take away a woman who he says was half naked.
"They took and she was naked from here to up and was without shoes," he said.
She was taken to Lenox Hill Hospital Annex, where she was pronounced dead a short time later.
OTHER NEW CASE DETAILS
The 51-year-old man called 911 again and agreed to voluntarily speak to detectives. Detectives interviewed him and Cerveny's husband. They were both released without any charges filed.
Detectives are still looking to talk with the 60-year-old taxi driver to get his side of the story. They are viewing surveillance video and obtained a search warrant for his apartment.
The woman was not robbed, according to police.
