Transcript for Putin critic who defected to Ukraine killed in Kiev
Next to Ukraine and the cold-blooded killing. Ukraine's president calling it an act of state terrorism by Russia. Laying there on the street in the middle of the day. Just a few months ago, he left Russia with his wife and young son, and now he is the latest victim of a violent end. ABC's Brian Ross has the story.

Police surround the body of a member of the Russian parliament, Dennis voronenkov, shot dead this morning on the streets of the capitol city kiev after defecting to Ukraine and publicly criticizing the Russian president. Just last month, voronenkov told a reporter for a TV network funded by the U.S. Aimed at Russia, that he accepted his fate as a Putin critic. A Kremlin spokesman tonight denies any role in the murder, but the president of Ukraine is calling it Russian state terrorism on orders of Putin. Just two days ago, another Putin critic, a Russian lawyer was thrown out of the fourth story of his apartment building and critically injured. Under the rule of Russian president Putin, more than a dozen critics have been targeted for assassinations. Lawyers, businessmen, journalists. Based on his public comments, none of it has seemed to bother president Donald Trump. Putin is a killer. A lot of killers. You think our country is so innocent? Reporter: A rush opposition told me that Putin's critics counted on the U.S. To help stand up further Russian president. Everyone against him must be very careful. Be afraid every minute. It's completely impossible for me. Reporter: One year after that interview, he was dead. Shot down under heavily guarded Moscow bridge near the Kremlin. We thank him for that report.
