LOS ANGELES, California (CNN) -- Michael Jackson had "some very unusual problems" that Dr. Conrad Murray did not know about when he was hired as Jackson's personal physician as the singer prepared for comeback concerts, Murray's lawyer says.
Dr. Conrad Murray, Jackson's personal physician, has had his home and office searched.
In comments published in the Los Angeles Times and confirmed Thursday by his spokeswoman, attorney Ed Chernoff said his client did not know which drugs Jackson might have been taking or whether he was addicted.
"When he accepted the job, he was not aware of any specific requirements regarding medications that Michael Jackson was taking or any addictions that he was suffering from," Chernoff told the Times.
In a quote confirmed by his spokesman, Chernoff said that it was only after Murray moved to Los Angeles in May that "he realized that Michael Jackson had some very unusual problems."
Murray did not conduct drug tests on Jackson and had no way of knowing, other than from Jackson himself, whether he was taking other drugs, Chernoff's spokeswoman, Miranda Sevcik, told CNN.
Investigators, trying to determine whether anyone should be charged in Jackson's death, have searched Murray's home and two clinics for evidence of drugs he may have given the singer.
One search warrant implied that police suspect Jackson was a drug addict. It said there was "probable cause to believe" that the searches would uncover evidence of excessive prescribing, prescribing to an addict, prescribing to or treating an addict and manslaughter.
It also cited "probable cause to believe" that the premises contained "records, shipping orders, distribution lists, use records relating to the purchase, transfer ordering, delivery and storage of propofol (Diprivan)."More
