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.
