Shocking footage shown in court showed the moment first responders said Jordan Neely still had a pulse after former Marine Daniel Penny strangled the troubled homeless man on a Manhattan subway last year.

Chaotic body camera footage capturing two officers confirming that an unconscious Neely still had a pulse when they arrived at Fulton Station on May 1, 2023, was shown to jurors in Penny’s involuntary manslaughter trial in Manhattan Supreme Court.

“I feel his pulse,” one officer said, while a second officer later confirmed that Neely “had a pulse” before he died.

A few minutes later, a police officer was heard saying, “He’s not breathing.”

The video shows paramedics trying to revive Neely through chest compressions, CPR, a defibrillator machine and a Narcan injection.

The dramatic footage was played as NYPD Officer Teodoro Tejada testified as the trial’s first witness on Friday.

The officer told prosecutors that Neely initially had a “faint pulse” when first responders arrived, but officers could no longer find a pulse minutes later.

Tejada also searched Neely for a weapon but found only a donut in his jacket.

According to the footage, a calm Penny could be seen calmly standing next to Neely’s unconscious body and casually chewing on what could have been gum.

Penny, 26, is accused of subjecting Neely, 30, to a fatal asphyxiation for more than six minutes on a crowded F train after the homeless man stormed into the locomotive “behaving erratically and threateningly” towards other passengers.

Penny, who faces up to 15 years in prison, is also heard in the video telling responding officers that he “knocked (Neely) down to the ground.”

Additional footage from NYPD Officer Dennis Kang’s body camera shows the officer yelling, “Man! Stay with me… yo!” He shook his stomach angrily to shake Neely awake.

“I felt a pulse several times, but initially I didn’t feel a pulse… the third time I felt a slight pulse,” Kang testified during direct examination, adding that Neely rubbed her sternum and did not do so. Give rescue breaths even though Neely cannot see him breathing.

He stated that the police teams did not have sufficient equipment when they arrived at the scene.

The body camera of NYPD Sgt. Carl Johnson showed officers performing chest compressions on Neely from a different angle before emergency workers arrived.

Johnson told the court he ordered Narcan during the chaotic scene and claimed Neely “was an obvious drug user and was very dirty.”

The trial is expected to last up to six weeks.
