Attorney Kathy Jorrie said Murray claimed he was giving up a $1 million a month medical practice to serve as Jackson’s doctor while the singer prepared for his ill-fated comeback concert series.

Murray is serving a four-year sentence for involuntary manslaughter in connection to the late star’s death. He was convicted in 2011 of administering the fatal dose of anesthetic propofol that killed Jackson in 2009.

Katherine Jackson is suing concert promoters AEG Live for what she claims was negligence in the hiring and supervision of Murray while her son was under his care.
