In 122 words, slain Officer Didarul Islam in an essay made it clear why he wanted to join the NYPD: they were there to protect New Yorkers and, he said, “I got inspired by their work.” Islam was one of four people shot dead by Shane Tamura at a Park Ave.

The father of NYPD Det. Didarul Islam, who was killed in last week's Midtown Manhattan office shooting spoke out Tuesday for the first time since his son's death.

Islam came to New York City from his native Bangladesh when he was 20 years old, with "the promise of a better life," NYPD Commissioner Jessica Tisch said.
