LOS ANGELES - Michael Jackson's doctor will face the singer's distraught family and ardent fans one more time when he returns to court for sentencing in the death of the superstar from an overdose of an operating-room anesthetic he was receiving to battle insomnia.

Dr. Conrad Murray's sentencing today for involuntary manslaughter is the final step in the criminal case launched within days of Jackson's unexpected death in June 2009.

Prosecutors want a judge to sentence the 58-year-old Murray to the maximum four-year prison term. Defense attorneys counter that Murray already faces a lifetime of shame and diminished opportunities and should receive probation.

Jackson's mother Katherine and several siblings routinely attended the six-week trial that ended with the conviction on Nov. 7.
