Police press hunt for gunman who killed passenger on moving NYC subway train in apparent random act

An unidentified gunman shot and killed another passenger on a moving New York City subway train Sunday morning in what police officials said appeared to be an unprovoked attack.

The shooting happened on a Q train traveling over the Manhattan Bridge at around 11:40 a.m., a time of day when subway cars are often filled with families, tourists and people headed to Sunday brunch.

Witnesses told police the gunman was pacing the last car of the train "and without provocation, pulled out a gun and fired it at the victim at close range," said the NYPD's Chief of Department, Kenneth Corey.
