The trial of Daniel Penny, the former Marine charged with killing Jordan Neely aboard a New York City subway, featured testimony from a man who helped the defendant restrain the victim.

The homicide detective who interviewed Daniel Penny shortly after he placed Jordan Neely in a chokehold on an uptown F train last year knew that Neely had died, he testified at Penny’s criminal trial Thursday. But Penny, he said, did not.

A city straphanger who jumped in to try to help Daniel Penny restrain Jordan Neely told jurors Tuesday that the troubled homeless man looked like he was trying to “escape” the Marine veteran’s chokehold.
