A jury has convicted former Hollywood private eye Anthony Pellicano and entertainment lawyer Terry Christensen of federal wiretapping conspiracy charges.

Pellicano and Christensen were each convicted Friday of conspiracy to commit wiretapping. Pellicano was also convicted of wiretapping and Christensen was convicted of aiding and abetting a wiretap.

The two were accused of secretly recording phone conversations of billionaire investor Kirk Kerkorian’s ex-wife, Lisa Bonder Kerkorian, in an effort to disprove her claims that the MGM mogul was the father of her daughter.

The 64-year-old defendants each face up to 10 years in federal prison and $500,000 in fines when they are sentenced Nov. 17 by U.S. District Judge Dale S. Fischer.
