Martinez said he also interviewed Jackson's son Prince at the hospital. But his handwritten notes of that interview were not allowed in evidence because the interview was not recorded.
Earlier, Martinez said that five days before Jackson died, his manager called the singer's doctor, told him Jackson was sick, and implored him to have blood tests done, according to a voicemail played in court.
The message left by Frank Dileo was retrieved by police from Murray's cellphone.
"I'm sure you're aware he had an episode last night," the message said. "He's sick. ... We gotta see what he's doing."
Plaintiff's lawyer Brian Panish acknowledged outside court that the episode occurred on the day Jackson was told by Kenny Ortega, the director of his "This is It" concert, to go home from a rehearsal because he was pale and shivering.
Panish suggested that if Dileo was aware of the incident, so were AEG executives. Jurors were not given any further details on the episode.
Katherine Jackson's lawsuit claims AEG didn't properly investigate Murray.
AEG denies it hired the doctor, and it is likely to blame Jackson for insisting on having Murray as his doctor because of his dependence on propofol, which Jackson used to sleep. The company alleges Jackson was addicted to numerous drugs.
