Defense attorneys quickly called their first two witnesses.
One was Dona Norris, a records custodian for the Beverly Hills Police Department who briefly discussed the timing of the 911 call received on the day Jackson died.
They also called a police surveillance specialist who retrieved grainy surveillance footage shot outside Jackson’s home on the day of his death.
The specialist, Alexander Supall, told jurors he only collected a few minutes of footage taken around the time Jackson arrived home after a June 25, 2009, rehearsal for his comeback concerts.
The witnesses were among 15 expected to be called by the defense over the next few days.
The final prosecution witness against defendant Dr. Conrad Murraywas Dr. Steven Shafer, an expert on the anesthetic propofol that authorities say killed Jackson.
Shafer, a Columbia University researcher and professor, said Jackson had been receiving propofol almost every night for more than two months, according to a police statement by Murray. The Houston-based cardiologist has pleaded not guilty to involuntary manslaughter.
Shafer previously testified that he thinks a propofol overdose killed Jackson. But he said Murray kept no records about how much of the drug he gave the singer.
Shafer told jurors that it’s difficult to know the precise effects of the drug on the singer because he had been given so much of it in the months before he died.
Shafer made the statement while being cross-examined by lead defense attorney Ed Chernoff, who noted the risk that Jackson would stop breathing should have been low after the first few minutes the drug was administered on the day he died.
Chernoff based that conclusion on models and research done by Shafer.
“In Mr. Jackson’s case, it’s harder to have that certainty,” Shafer replied. “There’s very little, almost no precedent for this level of propofol exposure.”
Shafer has said the only possible explanation for Jackson’s death based on the evidence was that Murray put the singer on an IV drip of propofol then left the room after the singer appeared to be asleep.
Murray’s attorneys will try to counter four weeks of damaging testimony from prosecution witnesses who have cast Murray as an inept, distracted and opportunistic doctor who repeatedly broke legal, ethical and professional guidelines.
Murray’s attorneys have not publicly revealed whether they will call him to testify.
Jurors have heard from the doctor through a more than two-hour interview with police, and it seems unlikely his attorneys would subject their client to what would be blistering questioning from prosecutors.
Shafer never retreated from his position that Murray is solely responsible for Jackson’s death and that the cardiologist committed 17 egregious violations of medical practices that each could have either led to Jackson’s serious injury or death.
Out of sight of the jury, the defense’s theory has shifted in recent months from arguing that Jackson swallowed propofol and gave himself the fatal dose to suggesting the singer had swallowed several pills of the sedative lorazepam that led to his death.
