Michael Jackson's doctor 'to be charged over death'
Michael Jackson's doctor is expected to be charged with the singer's involuntary manslaughter, US media reports say.
A spokeswoman for Dr Conrad Murray said he is expected to surrender to authorities within the next 48 hours.
If Dr Murray is charged, a judge would decide if he should then go on trial.
Michael Jackson's death, at the age of 50, in Los Angeles on 25 June last year was ruled as homicide, mainly caused by an anaesthetic.
A spokeswoman for the Los Angeles District Attorneys office told the BBC that so far nothing had been filed against Dr Murray.
Involuntary manslaughter occurs when a death is the indirect result of negligence or recklessness. A conviction can carry a lengthy prison sentence.
Powerful anaesthetic
If he is charged, the doctor would face a hearing at which a judge would consider the evidence and decide whether Dr Murray should go on trial.
Jackson's death was primarily caused by the powerful anaesthetic Propofol, the Los Angeles coroner confirmed in August.
A cocktail of drugs - also including sedatives Midazolam and Diazepam, the painkiller Lidocaine and the stimulant Ephedrine - were detected in his body.
Dr Murray told police he had been giving Jackson Propofol as part of his treatment for insomnia, according to an affidavit made public in August.
