Throughout his manslaughter trial, Daniel Penny has been stoic, disciplined and emotionless — never cracking a smile or a frustrated grimace. His posture is so straight, you could hang a painting flush against his back.

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.

Medical examiner Cynthia Harris ruled Neely’s May 2023 death a homicide by compression of his neck, due to the chokehold Penny placed him in on the floor of an uptown F train. On Friday, she testified that the chokehold provided the only reasonable explanation for Neely’s death.

The medical examiner who ruled Jordan Neely's death was a homicide caused by Daniel Penny's chokehold insisted Friday she'd stand by the ruling.

The witness said that he looked up from his phone and saw Daniel Penny struggling with Jorden Neely on the floor of the train and heard other bystanders ask those around them to call the police.

A subway commuter who helped an ex-Marine restrain an agitated man aboard a Manhattan subway last year testified that he tried to convince the veteran to loosen his grip around the man’s neck.
