NEW YORK — New York City’s chief medical examiner determined on Friday that suicide by hanging was the cause of death for financier Jeffrey Epstein, whose body was found six days ago in a Manhattan jail cell while awaiting trial on sex trafficking charges.The sparely worded official announcement detailing the autopsy conclusions rebutted a host of conspiracy theories - including one promoted by President Donald Trump - that had circulated on social media about the death of the well-connected former money manager.Epstein’s lawyers said they were “not satisfied” with the medical examiner’s conclusions and planned to carry out their own investigation, seeking prison videos taken around the time of his death.Epstein, 66, was found unresponsive on Saturday in his cell at the Metropolitan Correctional Center (MCC), triggering investigations into the circumstances of his death.
