Michael Jackson's doctor is expected to return to work Monday at his Houston medical clinic for the first time since before the pop star's death.

An attorney for Dr. Conrad Murray said the cardiologist plans to resume office hours Monday at the Armstrong Medical Clinic.

Murray was hired to be Jackson's personal physician during a world tour and was with Jackswon when the 50-year-old singer died on June 25.

Murray has been the focus of a homicide investigation in Los Angeles since telling police he gave Jackson a powerful operating room anesthetic to help him sleep.

Murray has not been charged with a crime.

Murray lives in Las Vegas.

His lawyer, Edward Chernoff, said Murray had to close an office there because his clients were being harassed.
