Dr. Conrad Murray has become the most infamous name in the Michael Jackson investigation. A frequent target for DEA raids in the course of the investigation, Murray is believed to have administered Propofol to Jackson. This could have caused the singer’s untimely death. No formal charges have been brought against Murray.

He’s now posted a YouTube video, ostensibly because he is “afraid to return phone calls or use my email.” In his message, the doctor thanks patients and friends for the supportive messages they’ve been sending. “Your messages give me strength and courage and keep me going. They mean the world to me.”

“Please, don’t worry. As long as I keep God in my heart and you in my life, I will be fine. I have done all I can do. I told the truth. And I have faith the truth will prevail,” he told viewers.

Michael Jackson’s body will be interred on August 29, the day that would have marked his 51st birthday. A quiet ceremony of friends and family will see him laid to rest.
