Murray's defense team now admits that Murray gave Jackson 25 mg of the creamy anesthetic propofol but argues that Jackson himself took an additional dose of propofol and a sedative without his doctor's knowledge, leading to his death. Propofol is typically administered in a hospital setting.
Cooper testified today that in a routine administration of propfol, or any sedative, she would have an additional person in the room as a monitor to keep track of the patient's vital signs.
Cooper did not recall Murray's demeanor on the day of Jackson's death or whether he was particularly "frantic," as Flanagan suggested.
"I recall speaking to him, and I assumed when I was speaking to him [that] I was getting honest and truthful answers," Cooper said.
Cooper declared Jackson dead after an hour and 13 minutes of attempted resuscitation "failed and seemed to be futile."
The fifth day of the trial marked the first time that Jackson's parents, Katherine and Joe Jackson, and his sister LaToya were not in court. Katherine Jackson reportedly left Los Angeles over the weekend with Michael Jackson's three children to attend the Canadian premiere of Cirque du Soleil's new show, "Michael Jackson: The Immortal World Tour."
Michael Jackson siblings Janet, Randy, Rebe and Jermaine, and Jermaine's wife, were in the courtroom today.
Also expected to testifying were three of Murray's girlfriends, including Sade Anding, who spoke to Murray on the phone right before Jackson's death.
A coroner ruled that Jackson died of "acute propofol intoxication" in combination with sedatives.
Prosecutors argue that Murray is criminally responsible for Jackson's death for administering propfol, a surgical anesthetic, to help Jackson sleep. They are accusing Murray of medical negligence and reckless use of the drug.
The defense argues that Jackson caused his own death by taking eight pills of lorazepam and orally taking propofol while Murray was out of the room.
Murray is charged with involuntary manslaughter and faces up to four years in prison if convicted.
