"It is like there are two people there. One (deep inside) trying to hold on to what he was and still can be and not wanting us to quit him, the other in this weakened and troubled state," Ortega wrote. "I believe we need professional guidance in this matter."
Ortega testified at Murray's trial about his concerns about Jackson's frail condition and missed rehearsals. It resulted in a meeting six days before Jackson's death in which Murray assured the promoters he would have Jackson ready for rehearsals that next week.
An e-mail from Phillips after that meeting said he had confidence in Murray "who I am gaining immense respect for as I get to deal with him more."
"This doctor is extremely successful (we check everyone out) and does not need this gig, so he (is) totally unbiased and ethical," Phillips' e-mail said.
The correspondence could play a role in a wrongful death lawsuit filed by Jackson's heirs against AEG, which accuses the promoter of contributing to his death by pressuring him to prepare for the concerts despite his weak condition.
A lawyer for Jackson's mother and a spokesman for Jackson's estate declined to comment on the e-mails reported in the newspaper.
