Conrad Murray’s lawyers blame Michael Jackson’s longtime doctor for making him an addict

Dr. Arnold Klein, Michael Jackson’s longtime doctor and friend, administered 51 Demerol injections to his client in the three months leading up to his death.

“Due to Mr. Klein’s actions, Mr. Jackson became physiologically and psychologically dependent on Demerol,” the documents say.

Murray’s lawyers now ask that the skin doctor hand over all of his medical records, insisting that “Dr. Klein is a relevant and highly material witness to the defense,” reports TMZ.
