Paris Jackson wants to make Conrad Murray pay for Michael Jackson's death.

Martial arts fan Paris has apparently vowed to "karate chop" the jailed doctor if he refuses to give evidence to get the Jackson family £26 billion in compensation.

A source told The Sun newspaper: "Paris wants to kick Murray's butt. She wants him to explain what pressure he was under to make Michael perform. When she gives evidence she plans to tear him apart."

Conrad is serving a four-year prison sentence for involuntary manslaughter, but is refusing to testify in the Los Angeles court about whether he was forced to give the 'Thriller' singer drugs.

He claims he is innocent of Michael's death and has recently launched a second appeal to leave prison while his case is being examined.

The disgraced physician told current affairs show 'Anderson Cooper 360' earlier this month: "If I testify, I will testify very honestly.

"It is a sad thing when I look at what's going on the television because if Michael was alive today he would be absolutely upset, he would be so unhappy with what is happening."
