Michael Jackson's weakened state during tours 'a defence evidence for Murray'

Late king of Pop Michael Jackson's weakened condition during various concert tours as well as preparations for the London concerts that never happened could prove to be a powerful evidence in the defence of Conrad Murray.

Sources linked with the criminal case have said there's "compelling evidence" that Jackson was in weakened health whenever he went on tour, reports TMZ.com.

Specifically, people who went on various tours-including the Bad and Dangerous concerts-have said that Jackson was frequently "dehydrated, medicated, and sleep-deprived." 

Just like with Murray, Jackson had a doctor who accompanied him during rehearsals and tours, attending to his needs.
 
The This Is It London tour was especially gruelling, because AEG added dozens of concert dates for Jackson, who was already in an extremely weakened state and terrified he would fail.

The defence has stated that when Murray walked out of the room and Jackson woke up, he accidentally infused himself with a fatal dose of the drug out of frustration and fear.
