Offer of a Murder Surfaces at Wiretap Trial LOS ANGELES â€” A hedge fund manager and art collector from New York testified under immunity Tuesday that Anthony Pellicano, the Hollywood private detective accused of wiretapping and racketeering, had once offered to have a movie producer killed for him. Adam D. Sender, the owner of Exis Capital, a hedge fund that at one point had more than $1 billion in assets, said in Federal District Court here that he had paid Mr. Pellicano about $500,000 to investigate Aaron Russo, a producer and onetime talent manager whose film credits included â€śTrading Places.â€ť Mr. Russo died of cancer last year. In 1999, Mr. Sender invested $1.1 million with Mr. Russo. Later, Mr. Sender sued Mr. Russo, accusing him of pocketing the money. Mr. Russo dodged process servers for more than a year, until Mr. Pellicano was brought into the case at the urging of Mr. Senderâ€™s new lawyer, Bert Fields. (Mr. Sender said he paid Mr. Fieldsâ€™s firm about $300,000, but recovered only $25,000 from Mr. Russo.) Mr. Sender testified Tuesday that Mr. Pellicano had wiretapped Mr. Russo for a year and had played recordings of Mr. Russoâ€™s intercepted phone calls for him 10 or 15 times. But Mr. Pellicano grew sick of listening to Mr. Russo, Mr. Sender said. And, in a â€śfrighteningâ€ť moment in the garden of Mr. Senderâ€™s mansion in Bel-Air, he said, Mr. Pellicano suggested killing Mr. Russo. Mr. Pellicano said that â€śif I wanted to, I could basically authorize himâ€ť to have Mr. Russo â€śmurdered on the way back from Las Vegas,â€ť Mr. Sender testified. â€śHe would have someone follow him back, drive him off the road and bury his body somewhere in the desert.â€ť Mr. Sender said he had declined.
