Washington, Aug 24 Michael Jackson's personal doctor should not be held responsible for the singer's death - because he was just trying to help, says the King of Pop's former friend and biographer J. Randy Taraborrelli.

According to reports, Los Angeles police are trying to build a case for manslaughter against Dr. Conrad Murray, who was staying with Jackson in the days leading up to his death on 25 June (09).

Taraborrelli insists Dr. Murray should not be blamed for Jackson's death.

"He (Jackson) had the burn on the back of his head (from a Pepsi commercial pyrotechnics malfunction) that never really healed, he had a lot of bad plastic surgery that was causing a lot of problems, he had arthritic problems in his knees and he could not sleep," Contactmusic quoted Taraborrelli as telling ABC News.

"I remember Michael complaining about not being able to sleep as far back as 1993... This was out of control.

"There has been a lot of Dr. Murrays in Michael Jackson's life, a lot... While it's easy to want to indict these men, and especially Dr. Murray, I think that it's also easy to understand that no one wanted to see Michael Jackson suffer, no one wanted to see this man live the kind of tortured life that he was living.

"People wanted to help him and I think that in the end they didn't go about it (in) the right way," Taraborrelli added. (ANI)
