Fateful Letter From Dr. Conrad Murray Revealed

ET has obtained a letter from Dr. Conrad Murray, Michael Jackson's former personal physician who is now being investigated for manslaughter, written to his patients last month explaining that he was leaving his medical practice indefinitely for a "once in a lifetime opportunity." Read on to see the letter.

In his June 15 letter to "patients and friends," Murray said he was seeking a "suitable replacement [doctor]" for himself, but intended to "manage the practice, and be involved as much as possible [from afar]," stating also, "please know my absence is not permanent."

Authorities raided Murray's offices on Wednesday, searching for manslaughter evidence in their investigation into the death of the King of Pop, who passed away on June 25.
