A decision on possible criminal charges over the June death of Michael Jackson is "months rather than weeks away", the Los Angeles Times on Monday quoted law enforcement sources as saying.
Authorities have consulted medical experts and say there is much evidence to review, the Los Angeles Times reported, and no charges are expected to be filed before 2010.
Police and prosecutors could not be reached for comment.
Police have been investigating Jackson's doctor Conrad Murray for months after coroners ruled Jackson's death a homicide. The official report said the anesthetic propofol and the sedative lorazepam were the primary drugs that led to the "Thriller" singer's sudden death on June 25..
Authorities have searched the Houston and Las Vegas offices of Murray, who has denied any wrongdoing and who was with Jackson, 50, on the morning of his death. He had been caring for the singer in Los Angeles as he prepared for a series of comeback concerts in the weeks before his death.
Meanwhile, Sony Pictures announced that the "This Is It" concert film compiled of Jackson's rehearsal footage would be released on DVD on January 26. The movie has earned more than $240 million at the global box-office since its October 28 release.
The DVD will include two documentaries on preparations for the planned comeback tour, features on the audition process and a Jackson memories feature.
