[bold] Wall Street executive dies after falling from New York apartment 'as he celebrated birth of baby' [/bold]
A high-flying Wall Street executive plunged to his death from the window of his fifth-floor apartment in New York last night.
Keith Mastronardi, 31, had been smoking and drinking heavily and was trying to open a window to air the room when he slipped and fell at about 10.25pm, according to police.
His wife, Debra, was at home with their three young children, including a newborn baby girl. It is believed the couple may have been celebrating her birth.
Mrs Mastronardi, who had also been drinking heavily, became hysterical and had to be carried out of the Upper East Side apartment on a stretcher, according to police sources.
The Wall Street Journal reports she was then taken to the New York Presbyterian Hospital for psychological evaluation.
His body was found in a courtyard behind the apartment building at around 10.30pm, according to police.
On Facebook, he is listed as father to two boys called Tyler and Luca. Last September he announced his wife was expecting a baby girl.
The children are being looked after by relatives.
Joe Gomez, an attendant at the parking lot next door, told the Daily News the sound of Mr Mastronardi hitting the ground was so loud he ran for cover.
He said: 'I heard a loud bang from the back. It sounded like a bomb - very hard. I never heard something like that before.'
His brother, Marc Mastronardi, told the Post: 'He was an amazing and loving father and we%E2%80%99ll really miss him.'
Mr Mastronardi studied at the University of Chicago and was head of exotic derivatives at the India-based firm Vyapar Capital Market Partners.
Vyapar CEO, Vinayek Singh, told MailOnline Mr Mastronardi had worked for the company for several years and was a 'valued member' of the firm.
He said: 'The family have spoken to us and said it was a tragic accident. They described him as a loving, caring husband and father.'
He had previously worked at EuroBrokers and Group One Trading.
Mr Gomez said: 'I'd see him passing by with the kids all the time and say hi.'
Gianluca Rottura, who owns a local wine store, told the Post the Mastronardis were regular customers, and the trader had come in about a week before to celebrate the birth of their daughter.
He said: 'Very, very nice couple. Always very happy together. The type of couple people would be jealous of.
"I saw him a week ago. He came in with his son to buy wine. And he said my wife was pregnant so we weren%E2%80%99t drinking for a while.'
Mr Rottura also paid tribute to the family. He told the newspaper: 'They were nice to everyone. Everyone loved them. When they walked down the street everyone said hello.
'They had a certain energy. The kids were happy. These are the type of people you look at and say how can I get that.'
Mr Mastronardi went to school in Mineola, New York, where he was state champion in the triple jump for the Catholic High School Athletic Association.
He was also triple jump champion for three out of his four years at the University of Chicago, and still holds the indoor record, according to the Wall Street Journal.
A spokesman for the NYPD said Mr Mastronardi's death was under investigation.
