The Brooklyn DA’s Office will hire an independent expert to reconstruct the death of a Black man struck by a police car that was chasing him. It is a new development that raises doubts about the NYPD’s version of events that lead to 27-year-old Tamon Robinson‘s death last April.

The New York Daily News reports that an independent accident reconstruction expert is expected to investigate whether Robinson struck a parked NYPD vehicle, fell to the ground, hit the back of his head and died as the NYPD claims in its report. The fatal collision left a sizable dent on the side of the vehicle, raising doubts over the NYPD’s account.

While the NYPD reportedly said there were no witnesses to the incident, the Brooklyn DA’s office has interviewed several. One spoke with the Daily News:

“I heard the cops say over their loudspeaker, ‘Stop f—— running!’ and that made me jump to the window,” said neighbor Zina Callahan, adding she was interviewed by prosecutors about what she heard and saw from her third-floor window.
