It’s my medical opinion that there are no alternative reasonable explanations for Mr. Neely’s death,” the medical examiner, Dr. Cynthia Harris, told jurors Friday.

( NewsNation) — In the trial of Daniel Penny, a man accused of killing a man experiencing homelessness and mental illness on the New York City subway, jurors are hearing from experts on chokeholds following an admission from a key witness that he lied to police.

A New York City medical examiner testified on Friday that the pressure from Daniel Penny’s chokehold caused Jordan Neely’s tongue and other soft tissue in his neck up and toward the back of his throat, blocking off his windpipe and causing him to suffocate.
