Stunning video from a surveillance camera at a Brooklyn hospital shows a woman dying on the floor of a psychiatric emergency room while staffers ignore her.

The video was released by lawyers suing Kings County Hospital alleging neglect and abuse of mental health patients at the medical facility.

The video shows the 49-year-old woman falling out of her chair at about 5:30 a.m. June 19, then lying face-down on the floor and thrashing around before going still. The woman died.

People nearby, including two security guards, do nothing to help. An hour passes before a fellow patient finally gets the attention of a staffer.

The tape also suggests that staff at the hospital might have faked medical charts belonging to the victim, Esmin Green, to cover her lack of treatment, the New York Daily News reported.

Her medical chart claims the Jamaica native got up to walk to the bathroom when she was actually writhing on the floor, the News reported. The records also have Green sitting quietly in her chair when she was already dead.

"Thank God for the videotape because no one would have believed this could have happened," Donna Lieberman, executive director of the New York Civil Liberties Union, told the Daily News.

The agency that runs the municipal hospital — the city's Health and Hospitals Corp. — fired six staffers, including the two security guards.
