Michael Jackson

Michael Jackson's mother, Katherine Jackson, is considering a wrongful death lawsuit in her son's death, her lawyer said.

"The possibility of a wrongful death action has been floated," attorney Burt Levitch told the Associated Press. "In that regard, no decision has been finalized. ... Dr. [Conrad] Murray's name has been floated because he is under investigation."

Authorities have searched Murray's home and offices in the past month. His attorney has said Murray should not be a target of criminal charges, and on Tuesday, Murray released a video statement, telling supporters "the truth will prevail."

TVGuide.com's calls to Murray's attorney, Ed Chernoff, were not immediately returned Tuesday.

Meanwhile, Los Angeles Superior Court Mitchell Beckloff signed off on the merchandising deal Monday between concert promoter AEG Live and merchandiser Bravado. It is expected to deliver $15 million to the singer's estate, according to the deal.

Katherine Jackson withdrew objections to the merchandising deal, but raised new ones regarding AEG's plan for an exhibition tour of the star's memorabilia. Beckloff delayed a decision on the tour until Friday. Katherine Jackson was concerned about the split of proceeds from the tour and whether it would bring money to the estate, the AP reports.

The tour would coincide with the October opening of a film featuring Jackson's final rehearsal footage. Beckloff approved the movie deal last Monday.
