The result of Michael Jackson's death reports will be released publicly early next week, according to Los Angeles coroner's office.
The toxicology test results will determine what substances Jackson had in his body when he died.
We're still on track, said Ed Winter, assistant chief coroner for Los Angeles County.
He said some results from toxicology tests are in and the rest should be ready later this week or early next week.
He also said his office will make an announcement when all the tests are done and will publicly release the results the next day.
Authorities are also investigating claims that the pop star took large amounts of prescription medications after the powerful sedative Diprivan was found in his home.
Jackson died of cardiac arrest at 50 on June 25 in UCLA Medical Center, Los Angeles.
