Michael Jackson's mother is suing the concert promoter behind the pop star's comeback tour, alleging fraud and other claims related to the singer's death.

The complaint filed in Los Angeles on Wednesday accused AEG Live, director Kenny Ortega and several other AEG executives of failing to honor its agreement to provide the doctor charged in the singer's death with lifesaving equipment.

It argues AEG Live is liable for the actions of Dr. Conrad Murray, who has pleaded not guilty to involuntary manslaughter in Jackson's death, at age 50.

"Due to AEG's actions and inaction, three loving children lost their father, a loving mother and father lost their son, the Jackson siblings lost their brother and the world lost its most celebrated entertainer,” it says.
