llness and death
On July 13, 2012, Duncan was taken to a hospital after suffering from a heart attack.[17] Media reports suggested that his girlfriend, Omarosa Manigault-Stallworth, had previously tried to save his life by performing CPR.[18] Duncan's publicist, Joy Fehily, issued a statement on August 6 that read he was moved from the Intensive-care unit but remained hospitalized following his heart attack.[19]
On September 3, Fehily quoted Manigault as saying that Duncan had died in the morning in Los Angeles. He added that celebrations of Duncan's life would be announced at a later date.[1][20] The statement also, for the first time, described Manigault as Duncan's fiancée.[21]
