Defence quiz expert in Jackson case
Defence lawyers for the doctor charged over Michael Jackson's death are to get their chance to question a key prosecution expert.
Dr Steven Shafer has been questioned by prosecutors for three court sessions, laying out his theories for why he thinks Dr Conrad Murray is responsible for Jackson's death.
On Thursday, Dr Shafer walked jurors through various theories about how Jackson could have died because of a lethal dose of the anaesthetic propofol.
He says the only viable theory supported by the evidence is if Murray placed Jackson on an IV drip and left him for some period of time.
Lawyers for Murray, who has pleaded not guilty to involuntary manslaughter, have been waiting for the chance to challenge Dr Shafer's testimony.
Afterwards, the defence team will begin calling their own witnesses.
On Thursday, the court was told by a medical expert that Jackson was so heavily drugged in the hours before his death that he would have been incapable of self-administering the massive dose of propofol that killed him.
