On August 29, 2008, Pellicano was found guilty of conspiracy to commit wiretapping. Specifically, Pellicano had recorded phone conversations of Kirk Kerkorian's ex-wife, Lisa Kerkorian, in an effort to disprove her claims that Kerkorian was the father of her daughter. Sentencing was scheduled for November, 2008 then deferred to December 15, 2008. Pellicano was sentenced to 15 years in federal prison. The U.S. 9th Circuit Court of Appeals upheld the majority of his convictions, overturning only two for aiding and abetting computer fraud and unauthorized computer access. The most serious convictions, for running a criminal enterprise, remain intact.
