Jordan Neeley’s death was a direct result of the chokehold Daniel Penny held him in, a medical examiner testified Friday, rebutting assertions from the defense team that the former Marine did not apply enough pressure to kill the subway rider and that his death could have had some other cause.

The medical examiner who analyzed Jordan Neely’s body after Daniel Penny kept him in a chokehold on an uptown F train last year could not identify any other reasonable explanation for his death besides compression of his neck, she testified during Penny’s Manhattan criminal trial on Friday.

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.
