LOS ANGELES (AFP) - A judge sentenced Michael Jacksons doctor Conrad Murray to the maximum four years in jail on Tuesday, three weeks after he was convicted of involuntary manslaughter in the stars 2009 death. He has absolutely no sense of remorse, said judge Michael Pastor, after giving a scathing summary of the case against the 58-year-old doctor. There are those that feel that Dr Murray is a saint. There are those that feel that Dr Murray is the devil. Hes neither. Hes a human being. He stands convicted of the death of another human being, said Pastor. But he said: Michael Jackson died not because of an isolated one-off occurrence or incident. He died because of a totality of circumstances which are directly attributable to Dr Murray. The judge said he agreed that Murray should have to pay restitution to Jacksons estate and children, but said the amount would be decided at a later hearing scheduled for January 23. Prosecution had asked for Murray to pay $100 million to compensate Jacksons family for the lost earnings the singer would have made from a 50-show series of comeback concerts he was planning when he died. Murray was found guilty of involuntary manslaughter on November 7 for administering to Jackson an overdose of the powerful clinic anesthetic, propofol, in a bid to help him sleep. The medic admitted he had given the drug to the star for up to two months before his death.
