Prosecutors plan to call a coroner's toxicologist to explain to jurors in Los Angeles hearing the involuntary manslaughter case against Michael Jackson's doctor more about the drugs found in the late King of Pop and his bedroom.
Deputy district attorney David Walgren lined up more than three dozen bottles of prescription medications in front of jurors during evidence.
He told a judge he plans to call a toxicologist and possibly medical experts as witnesses on the trial's seventh day.
The witnesses are expected to fill in details in the case against Dr Conrad Murray and explain the relationship between the drugs, including the anaesthetic propofol.
Authorities contend that Murray administered a lethal dose of propofol and sedatives on June 25, 2009, but Murray's lawyers claim Jackson gave himself the fatal dose.
