A "smoking gun" e-mail allegedly connecting a concert promoter to Michael Jackson's death was revealed this week as a judge unsealed documents in the wrongful death lawsuit filed by Jackson's mother and children.

The trial next month in Los Angeles could shed new light on the pop icon's last days as Dr. Conrad Murray, who did not testify at his own involuntary manslaughter trial, and Jackson's oldest son Prince, 16, are on the witness list.

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 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, Katherine Jackson, contend that AEG Live's pressure on Murray to have Michael Jackson ready for daily rehearsals despite his fragile health led to his death from an overdose of surgical anesthetic.
