Plot Synopsis

ROBERT DURST: AN ID MURDER MYSTERY is a two-night, four-hour documentary special that delves into the twisted truth behind one of New York's most infamous real estate heirs: millionaire Robert Durst. From the suspicious disappearance of Durst's wife, Kathleen, to the execution-style murder of his confidant, Susan Berman, and finally the brutal killing of his neighbor, Morris Black, this special event pulls the curtain back on this 40-year saga. ROBERT DURST: AN ID MURDER MYSTERY -- which premieres from 9-11pm ET/PT on Monday, January 21 and Tuesday, January 22, 2019 on Investigation Discovery -- is an unabridged look into the investigation of Durst for the murder of Berman, who was found shot execution-style nearly two decades ago. While Durst maintains his innocence, many suspect he killed Berman to prevent her from telling police the truth about his wife Kathleen's suspicious disappearance from New York in 1982. This special builds on the explosive news coming out of HBO's THE JINX to bring viewers a comprehensive, 360-degree exploration into the case starting from the very beginning and extending to new information from the present day. All-new and exclusive interviews featured throughout this two-part limited series include Jim and Sharon McCormack, Kathleen's brother and sister-in-law; Ruth Mayer and Ellen Strauss, Kathleen's friends; Dick DeGuerin, Durst's defense attorney; and Susan Criss, the former judge who presided over the 2003 trial for the murder of Morris Black where Durst was acquitted. Others featured throughout the mini-series include legal experts and journalists who've followed the rollercoaster case the last four decades including legal analyst Beth Karas; true crime journalist Diane Dimond; crime reporter Jane Velez-Mitchell; and New York Times reporter Charles Bagli.
