The Killing of Henryk Siwiak: New York City’s only unsolved murder on 9/11.

At the end of an impossible day… when it felt like the world fractured wide open… the detectives in the 79th precinct received an unexpected report. There’d been a murder in Brooklyn. When they arrived the circumstances became even more strange. The victim was a polish immigrant who was never supposed to be in this neighborhood. 20 years later the case is still unsolved.
