The trial of Michael Jackson's doctor is resuming with jurors due to hear more about the powerful anaesthetic that killed the King of Pop.
Dr Steven Shafer, a leading expert on propofol, will resume giving evidence for the prosecution about its effects on Jackson.
The resumption of the manslaughter case against Dr Conrad Murray comes after three and a half court days in which proceedings were delayed.
Jurors heard briefly from Dr Shafer on Thursday before the trial was halted because of the professor's schedule and then the death of his father. He is expected to be the prosecution's last witness.
Murray's lawyers will begin calling their witnesses on Friday, and their case is expected to conclude by Wednesday.
