Michael Jackson's doctor has been found guilty of the singer's involuntary manslaughter.
The jury deliberated for about nine hours on the fate of Dr Conrad Murray following a six-week trial in Los Angeles.
Their guilty verdict was unanimous.
The jurors had been asked to decide whether Murray was criminally negligent in his use of the surgical anaesthetic propofol to treat the pop singer's insomnia.
They were also told to consider whether the propofol significantly contributed to Jackson's death on 25 June 2009.
The defence contended Jackson gave himself the fatal dose.
Murray, 58, sat silently and remained expressionless as the verdict was read out.
Fans of Jackson have gathered outside the courthouse, some holding placards labelling Murray a killer.
They cheered when the verdict was announced and chanted "Guilty, Guilty."
Murray was denied bail ahead of his sentencing on 29 November.
He faces a maximum prison term of four years and could also lose his licence to practise medicine.
Members of Jackson's family were in court for the verdict and the BBC reports his mother, Katherine, burst into tears as she heard the guilty verdict.
Prosecutor David Walgren thanked the jury and said sympathies should got to the Jackson family for the loss they have suffered.
"Not a pop icon but a son and a brother and I think that is most important to keep in mind today."
