Michael Jackson was killed with a lethal dose of anaesthetic by his personal physician Dr Conrad Murray, a jury has decided at the doctor's trial in Los Angeles. Following a six-week case, cardiologist Dr Conrad Murray, 58, was convicted of involuntary manslaughter after the jury decided his treatment of the singer had been criminally negligent. Murray, who will lose his medical licence, sat stone-faced as the unanimous verdict was delivered. He was handcuffed and remanded in custody for sentencing on Nov 29th. He faces a maximum sentence of up to four years in prison. In court, members of the late singer's family shouted "Yes" as the verdict came down. Jackson's mother Katherine sobbed quietly. Later, outside court, she said: "I feel better now." As Murray, wearing a light grey suit, was led out of the courtroom in handcuffs he cast a final glance at his own mother, who whispered the words "I love you."
