WASHINGTON, (Reuters) – An imprisoned Salvadoran  immigrant has been charged with the 2001 murder of a former  U.S. government intern, a case that helped end a California  congressman’s career, police and prosecutors said on Tuesday. The killing of 24-year-old Chandra Levy had been one of  Washington’s most sensational unsolved crimes. At first, it  received worldwide attention but interest faded after the Sept.  11 attacks in 2001 and as it became a cold case.

U.S. Attorney Jeffrey Taylor said an arrest warrant was  issued for Ingmar Guandique, 27, a Salvadoran immigrant in  prison for attacking two women in the same Washington park  where Levy’s remains were found.

Gary Condit, a Democratic congressman from California who  was married, came under scrutiny amid the media storm that  followed the May 2001 disappearance of Levy, whose remains were  later found in Rock Creek Park.
