Michael Jackson's personal physician, Dr. Conrad Murray, whose offices and home have been searched in the investigation into Jackson's death, thanked supporters and expressed faith that "the truth will prevail" in a video statement released Tuesday.

"I want to thank all of my patients and friends who have sent such kind emails, letters and messages to let me know of your support and prayers for me and my family," Dr. Conrad Murray says in the one-minute video. He says he decided to film a video because he is afraid to return calls or e-mails personally in light of "all that is going on."

"Your messages give me strength and courage and keep me going. They mean the world to me," he continues. "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 that the truth will prevail. God bless you and thank you."

On Monday, an attorney for Jackson's mother, Katherine Jackson, said the matriarch was considering a wrongful death lawsuit and that Murray's name "has been floated." Murray's attorney has previously said his client, who was with Jackson when he died June 25, should not be a target for criminal charges.
