New York Police Department officers believe to have identified one of the two men seen on video helping ex-marine Daniel Penny restrain Jordan Neely during a subway confrontation earlier this month. The former US Marine choked a homeless street performer on the Manhattan F train, Jordan Neely, to death on the subway car earlier this month. Neely’s death was ruled by the New York medical examiner’s office as a homicide due to compression against his neck. Video footage and eyewitness accounts show a man believed to be Mr Penny with his arm wrapped around Neely for several minutes until his eyes shut and his body goes limp. On 11 May, the Manhattan District Attorney’s office announced Mr Penny would face a charge of second-degree manslaughter. He turned himself in to authorities in Manhattan the following morning, and he was released after posting $100,000 bail after a brief arraignment hearing. His next appearance is scheduled for 17 July. Sources told New York Post that the authorities have been scouring the surveillance footage and believe one of the two men who helped 24-year-old Mr Penny pin down the homeless man has been identified. In the video, one man can be seen trying to tie up Neely’s arms, and the other put pressure on Neely’s shoulder. The source was quoted as saying that the NYPD officials have yet to speak with the person identified in the video. In the video that was captured by a bystander on 1 May, 30-year-old Neely was seen yelling at others and throwing trash. In a statement shared with The Independent on 5 May, attorneys for Mr Penny said that when Neely “began aggressively threatening Daniel Penny and the other passengers, Daniel, with the help of others, acted to protect themselves, until help arrived”. Widely shared video footage captured by journalist Juan Alberto Vazquez shows a man believed to be Mr Penny and two other men holding Neely to the floor of a train car on 1 May. Police initially questioned but did not arrest Mr Penny. Meanwhile, attorneys for Neely’s family said the statement from Mr Penny’s legal team was neither “an apology nor an expression of regret” but “character assassination and a clear example of why he believed he was entitled to take Jordan’s life.” Neely’s family has said Mr Penny should be tried for murder. The former US Marine was formally charged with second-degree manslaughter.
