Katherine Jackson has decided to take Dr. Conrad Murray "down" as she is upset with all the things he said about her late son Michael Jackson.
The 83-year-old matriarch of the Jackson family "made it her mission" after the medic made a series of embarrassing revelations about the star, including claims he was incontinent at night and had to have a catheter fitted to him before bed, Contactmusic reported.
Sources told Globe magazine that Murray, who served two years for the involuntary manslaughter of the King of Pop, is a "delusional liar" and said that the mother of MJ has been hurt a lot by him and she will "ensure he pays dearly".
