Anesthesiology expert Dr. Steven Shafer holds a bottle of propofol as he testifies for the prosecution during Dr. Conrad Murray's trial in the death of pop star Michael Jackson in Los Angeles October 20, 2011. The claim by attorneys of Murray, Michael Jackson's doctor, that the singer killed himself with an injection of the powerful anesthetic propofol is a "crazy scenario," a top anesthesiology expert testified on Thursday.
