U.S. Intelligence Chief: Boris Nemtsov’s Killer Likely to Remain a Mystery

U.S. Director of National Intelligence James Clapper said Monday that the facts surrounding Friday’s shooting of Russian activist Boris Nemtsov likely will never be uncovered.

He called the possibility that Russian political leaders were involved in Mr. Nemtsov’s death an “obvious theory,” but noted that people close to Russian president Vladimir Putin are alleging the U.S. government was behind the killing in order to spark division within Russia.

“We don’t have any unique insight into who did this,” he told the Council on Foreign Relations in New York. “I would venture the history has been we never do find out.”
