KIEV (Ukraine): A former police commander in Ukraine was convicted of strangling an investigative journalist and sentenced to life in prison on Tuesday, but the court has failed to determine who ordered the killing that has marred the ex-Soviet nation's image.    

Heorhiy Gongadze, co-founder of a news website who exposed high-level corruption, was kidnapped in September 2000 and his decapitated body was found in a forest outside Kiev several months later.

On Tuesday, the Pechersk District Court in Kiev convicted Olexiy Pukach, the former chief of the Ukrainian Interior Ministry's surveillance department, of the murder. Three other police officers have been convicted and sentenced in the case.

Gongadze's widow, Myroslava, who has received political asylum in the United States with her two daughters, has blamed then-President Leonid Kuchma for her husband's death. Her lawyer, Valentyna Telychenko, said she would appeal Tuesday's verdict as the court had failed to determine who ordered the killing.    Asked by reporters to comment on the verdict, Pukach suggested that they ask Kuchma and his former chief of staff, Volodymyr Lytvyn.     “I have told everything during the interrogation and the trial, so ask Lytvyn and Kuchma about their motives and intentions,” Pukach said before the guards took him away. His trial was held behind closed doors and the public was allowed only to hear the verdict.

Kuchma, the mentor of incumbent Viktor Yanukovych, was accused of involvement in Gongadze's murder based on audio recordings secretly made in his office in which he allegedly discussed a plot against the journalist. Kuchma has denied the accusations.    Prosecutors opened an investigation of Kuchma in 2011, but a court dropped the charges against him later that year.

In September 2000, Gongadze got into what he thought was a taxi and was joined by three other men. He was driven outside Kiev where Pukach and his accomplices took off the journalist's shoes and jacket, bound his hands and feet and put him on the side of a pit they dug.

The court said Gongadze was pleading for his life, but Pukach strangled him, first with his hands and then with a belt. Gongadze's body was then doused with gasoline and burned.     Pukach later returned to the scene to decapitate the corpse.

Gongadze's murder triggered months of protests against Kuchma, which served as a precursor to the 2004 Orange Revolution that overthrew Yanukovych's fraud-tainted victory in the presidential vote.

Pro-western President Viktor Yushchenko, who succeeded Kuchma, has pledged to find the truth about Gongadze's killing, but the probe dragged on for years without determining the mastermind.
