Michael Jackson's doctor returns to work in Houston

Michael Jackson's doctor Conrad Murray, who is the subject of an investigation into the death of the singer, has returned to work.

The cardiologist has resumed work at his medical clinic in Houston for the first time since the late singer's death on June 25.

"He has not been able to earn a living since the death of Michael Jackson," his lawyer Ed Chernoff told the Associated Press. "His legal fees are enormous and his debts have mounted to the point where it is unclear whether he will be able to keep his house or support his family.

"His intentions are to attend to these patients who have continued to support him, despite the attention and despite the threats."
