Foul play has been ruled out after a preliminary autopsy of Michael Jackson's body but several questions remain unanswered on the cause of his sudden collapse and death on Thursday.
"There was no indication of any external trauma or indication of foul play on the body of Jackson," Coroner's spokesperson Craig Harveye said after the autopsy.
The 50-year-old 'King of Pop' collapsed early Thursday at his rented Holmby Hills home in Beverly Hills. The pop star was rushed to the to UCLA Medical Center by paramedics where he was pronounced dead after attempts to revive him failed.
"We anticipate being able to close the case and issuing a final cause of death after those tests are completed in four to six weeks," Harveye said.
"We know he was taking some prescription medications," Harvey was quoted as saying by Los Angeles Times. However, he did not elaborate.
Meanwhile, many conspiracy theories have come up as to what led to Jackson's sudden death. People close to Jackson have already claimed the role of "enablers", who encouraged his dependency on prescription drugs.
