More women have come forward accusing a Denver cardiologist of rape.
Stephen Matthews, 35, was first charged with drugging and raping a woman he met on the dating app "Hinge." Matthews was later charged again as the nine additional victims revealed similar stories.
Matthews now faces 51 felony counts related to the alleged drugging and sexual assault of thirteen women. Three of the cases allege that Matthews drugged and subsequently raped the “helpless” victim. The remaining  cases allege that Matthews drugged the victims.    
Matthews’s attorney, Douglas Cohen, said his client is innocent, entering a not guilty plea in court.  Matthews' trial is set for next Spring.
