Lawyer Alan Dershowitz, who has helped win acquittals for some of the most famous criminal suspects in the United States, intends to use his evidence-busting skills to defend the former Ukrainian president accused in the murder of an investigative journalist more than 10 years ago.

Dershowitz said Monday that he was drawn to the case by a recording that prosecutors say incriminates former President Leonid Kuchma. A voice on the tape that sounds like Kuchma’s is heard complaining about journalist Heorhiy Gongadze and suggesting that someone “deal” with the problem.
