Russian Intelligence Expert Shot

WASHINGTON -- An expert on Russian intelligence has been critically injured in a shooting in front of his suburban Washington home, authorities said.

The shooting on Thursday of Paul Joyal, 53, came days after he accused the Russian government of involvement in the poisoning of former Federal Security Service agent Alexander Litvinenko. The FBI was assisting in the investigation.

Joyal was shot by two men in his driveway, police said.

The shooting appeared to be a random robbery and street shooting, said a law enforcement official with knowledge of the case. The official spoke on the condition of anonymity because he did not have authority to comment on the case.

In an interview broadcast last Sunday on the television news program "Dateline NBC," Joyal also accused the Russian government of trying to silence its critics.

"A message has been communicated to anyone who wants to speak out against the Kremlin: If you do, no matter who you are, where you are, we will find you, and we will silence you in the most horrible way possible," Joyal said.

President Vladimir Putin and Russian officials have repeatedly denied involvement in the Litvinenko case.

Joyal and Litvinenko were acquaintances, said Oleg Kalugin, a former KGB counterintelligence chief who is now a U.S. citizen and who met with Joyal several hours before he was shot.
