"AEG did not even try to get Dr. Murray to talk," Boyle said. "AEG is simply not telling the truth. AEG can't run from the fact that they hired the man who is in jail for killing the greatest entertainer the world has ever known."
Wass, who unsuccessfully objected to the deposition, said she advised Murray to invoke his Fifth Amendment right to not answer questions because of his appeal. The appeal brief is expected to be filed next week.
Jacksons plan to use e-mails
Jackson died two weeks before his "This Is It" comeback concerts, organized by AEG Live, were to have debuted in London in the summer of 2009.
E-mails the Jackson's plan to use in their case suggested that the promoter was worried about Jackson's missed rehearsals and they sought Murray's help in getting him ready.
Prince, Paris and Blanket Jackson and their grandmother contend that AEG Live's pressure on Murray to have Jackson ready for daily rehearsals despite his fragile health led to his death from the propofol overdose.
A cornerstone of the Jacksons' case is an e-mail AEG Live Co-CEO Paul Gongaware wrote 11 days before Jackson's death.
The e-mail to show director Kenny Ortega addressed concerns that Murray had kept Jackson from a rehearsal the day before: "We want to remind (Murray) that it is AEG, not MJ, who is paying his salary. We want to remind him what is expected of him."
Jackson lawyers, calling it a "smoking gun," argue the e-mail is evidence that AEG Live used Murray's fear of losing his $150,000-a-month job as Jackson's personal physician to pressure him to have Jackson ready for rehearsals despite his fragile health.
Billions at stake
The lawsuit seeks a judgment against AEG Live equal to the money Jackson would have earned over the course of his remaining lifetime if he had not died.
If AEG Live is found liable, it could cost the company several billion dollars, according to estimates of Jackson's income potential.
AEG Live is a subsidiary of AEG, a global entertainment company that was recently for sale with an $8 billion asking price.
The company announced last week it was no longer for sale.
