The widow of a Brooklyn man who died when he fall off an escalator last year is suing the Mets. 36-year-old Antonio Narainasami plunged 30 feet to his death when an escalator stopped suddenly at the Mets' old home. The lawsuit says that the escalator jerked, sending him over the railing and complains that it was "too steep, poorly maintained and needed higher railings." At the time of the accident last April, there was some speculation as to whether or not Narainasami was trying to slide down the rails when he fell. It was also customary for escalators at Shea to turn off in the seventh inning of games. The lawsuit filed in Queens Supreme Court by Ambeeka Narainasami also names the city and the elevator companies, Brink and Otis, as co-defendants. A lawyer for the city said, "We will review the case thoroughly, especially in a tragic case like this."
