NYC subway push victim Sunando Sen was graphic designer

Friends and co-workers described a man pushed from a Queens subway platform into the path of an oncoming train as a brilliant graphic designer, while police continued searching for the woman suspected of shoving him to his death.

The victim -- the second man to die after being pushed from a city subway platform this month -- was identified Friday by a law enforcement source as Sunando Sen, 46, of Corona, Queens.

"People have been coming to remember him with us," said Bidyut Sarker, 55, Sen's boss at NY Copy & Printing on 11th Street in Manhattan. "He was brilliant. He was kind. We all miss him."

Sen was killed around 8 p.m. Thursday night after he was shoved to the tracks from behind as he stood on the northbound platform of the 40th Street and Queens Boulevard No. 7 elevated train. Last night police released a drawing of the woman suspected in his death.

Earlier, police had released a video showing the woman, described as 5-foot-5, heavyset and in her 20s, running from the subway station.

Sen was originally from Calcutta, and had moved to the United States in the 1990s, Sarker said. Sen was recovering from a recent stroke but had opened a printing and copy business with a partner, Sarker said.

Witnesses said the man was pushed by the woman after she was seen "walking back and forth on the platform, talking to herself, before taking a seat alone on a wooden bench near the north end of the platform," said NYPD spokesman Paul Browne in a statement.

As the train arrived, she stood and pushed the victim off the platform, Browne said.

The manager of Sarker's shop, Alamgar Bhuiya, 40, said "we need to make sure that people who are mentally sick shouldn't walk around like that in the New York City subway station."

At a news conference Friday, Mayor Michael Bloomberg and police Commissioner Ray Kelly called the incident isolated. "We do live in a world where our subway platforms are open and that's not going to change," the mayor said. "There's always going to be somebody, a deranged person," he said.

Earlier this month, a Queens man was killed when he was shoved in front of a train at the 49th Street station. A homeless man has been arrested and charged in that case.

Sarker said he is planning a ceremony at a Hindu temple for Sen. "He was such a smart, intelligent man," Sarker said.

Sen's former roommate in Queens, Rizwan Khan, recalled him as a music lover with a massive CD collection who "was so good with computers and numbers, you thought he was from a different world."
