SANTA MONICA, Calif. (Reuters) - A man pleaded guilty on Thursday to breaking into Elle Macpherson`s home, stealing nude photographs of the Australian actress-model and threatening to post them on the Internet if she did not pay him. Michael Mischler, whose lawyer claimed had been jilted by Macpherson, faces up to six years and eight months in prison when he is sentenced Dec. 15. The Australian model says she has never met Mischler or his alleged accomplice William Holt, who pleaded guilty to attempted extortion on Thursday and was immediately sentenced in Santa Monica Superior Court to one year in jail. Mischler pleaded guilty to one count of attempted extortion and one count of first-degree burglary. Eight other charges will be dismissed as part of a plea agreement, said Deputy District Attorney Mike Duarte. Prosecutors alleged Mischler broke into Macpherson`s Los Angeles home several times last year. She reported cash, blank checks, jewelry and letters were taken, as well as the nude pictures of herself which she said she took with a self-timer camera. Mischler later gave Macpherson one of the letters and threatened to expose the photos if she did not pay him $60,000, prosecutors said. Mischler and Holt were arrested when they went to her home last July to collect the money. Macpherson has filed a defamation suit against Mischler`s attorney, Lawrence Young, seeking $5 million for publicly saying she and Mischler had a sexual relationship and that Mischler was her "boy toy."
