Michael Jackson's personal physician, the target of a police manslaughter investigation, released a video Tuesday thanking his patients and friends for their support.

Las Vegas cardiologist Conrad Murray's remarks in the one-minute video posted on YouTube are his first public comments since the pop icon's death on June 25.

In the video, a somber-looking Murray briefly refers to interviews he gave Los Angeles police detectives, saying, "I told the truth and I have faith the truth will prevail."

Law enforcement sources told The Times last week that on the morning the pop singer died, Murray left the performer alone and under the influence of a powerful anesthetic to make telephone calls, according to three people familiar with the investigation. By the time the doctor returned, Jackson had stopped breathing, the sources said.

Murray has been identified in court records as a suspect in a police manslaughter investigation.

He legally acquired the operating room drug propofol from a Las Vegas pharmacy and gave it to Jackson as a treatment for insomnia, the sources said.

His attorney has denied Murray did anything wrong.
