Katherine Jackson

Katherine Jackson wants Conrad Murray to give evidence in court.

Michael Jackson's mother needs the jailed doctor to testify in her wrongful death lawsuit against AEG, in a bid to prove the company negligently hired Murray - who is serving a four-year sentence for involuntary manslaughter for inadvertently supplying the dose of anaesthetic Propofol that killed the King of Pop in June 2009 - and failed to supervise him.

According to gossip website TMZ, the showbiz matriarch needs Murray on the record to prove AEG hired him, but the disgraced doctor is refusing to co-operate.

His lawyers Valerie Wass and J. Michael Flanagan are trying to make the order invalid on technical grounds.

This comes just weeks after the physician launched a second appeal over his conviction for manslaughter.

Murray wants to leave prison and serve the rest of his sentence under house arrest as he believes he is not a threat to the community or a flight risk since he has a young child who lives in Los Angeles. His first attempt at appeal was denied last autumn.

Moreover, he is still insisting he has been wrongly convicted for Michael's death and is allegedly passing his time in his prison cell by writing a 'tell-all' book about his time with 'Thriller' hitmaker.

A source recently commented: 'Dr. Murray spends most of his days writing what he is telling friends will be a tell-all book about what really happened in the final days of Michael Jackson's life.

'Murray believes that the public will want to hear about the time he spent with Michael.'
