The LAPD investigation into the death of Michael Jackson has been completed, according to reports.

Detectives are expected to present the case to the Los Angeles County District Attorney within weeks.

TMZ reports that the investigation was "exhaustive" and "extremely thorough", and that Jackson's doctor, Conrad Murray, is likely to face criminal charges.

Dr Murray is reported to have been with Jackson in the hours before his death on June 25th last year.

US media reports have maintained that the physician, who was working with the singer ahead of his comeback shows in London, administered a powerful sedative to the star.
