Defence lawyers for concert promoters AEG Live have rested their case in the Michael Jackson wrongful death trial.

Attorneys presented a videotaped testimony from the King of Pop's physician Dr. Allan Metzger as they brought their argument to a close on Wednesday (18Sep13), using the medic's account of his final interactions with Jackson to paint the pop superstar as an energised and determined figure prior to his 2009 death - contrasting claims suggesting he was a tortured soul, under pressure from gig bosses to perform his ill-fated This Is It residency in London.

In the footage, Metzger revealed his famous client signed up for the shows in an effort to rebuild his reputation following his sensational child molestation trial and acquittal in 2005.

The doctor said, "He wanted to redeem Michael Jackson. He wanted to redeem his image. He felt this was it and he wanted to go out with a flash. He was still terribly hurt about the trial and the accusations."

However, Jackson was said to be anxious about the big stage return and asked Metzger to prescribe him an intravenous sleep medication. The physician refused, warning him about the potentially-fatal dangers of the drug.

The Thriller hitmaker's mother, Katherine Jackson, and his three kids are suing AEG Live chiefs amid allegations they were negligent in hiring disgraced medic Conrad Murray as his personal doctor as the superstar worked on his London comeback.

AEG Live executives have denied responsibility, insisting that Jackson was the one who personally employed Murray, who is currently behind bars after being convicted of administering the fatal dose of anaesthetic propofol that claimed the singer's life in June, 2009.

Closing arguments and jury deliberations are expected to begin next week (begs23Sep13) after Katherine Jackson's lawyers present their final arguments.

The trial is now in its 21st week.
