The Upper East Side co-op from which a Wall Street exec tumbled to his death Sunday should have had window guards — and the city today is sending inspectors to check all of the building’s other apartments.
Keith Mastronardi, 31, lived on the fifth floor at 340 E. 74th St. with his wife and three small children, and — by law — anyone with kids under 10 should have window guards, according to the Department of Housing Preservation and Development.
HPD had received no complaints about the building, a spokesman said yesterday.
Mastronardi spent the day in John Jay Park with his wife and kids and had two martinis after getting home, said his mom, Charlene, of Seaford, LI.
He decided to have a cigarette, so he cracked open a waist-high window, she added, so that the fumes wouldn’t bother his wife and 11-week old daughter, who were also in the bedroom.
But he leaned too far.
“Debra turned to Madison and looked back, and he was gone,” said the grieving mother. “She heard a thud, the bang, and went to look out the windows and saw him there.”
The couple was to close today on an Oyster Bay home. Instead, a devastated Debra Mastronardi is planning a funeral.
Debra, 32, had to be taken out of the apartment on a stretcher after what cops have ruled an accident.
Keith was head of USD exotic derivatives at Vyapar Capital Market Partners.
