Like Father, Like Son? Conrad Murray's Dad Once Cited for Medical Misconduct

July 23, 2009— -- As investigators sifted through the evidence from the raids on the office and storage unit of Michael Jackson's doctor, Dr. Conrad Murray, ABCNews.com learned that Murray's father once ran afoul of the Texas Board of Medical Examiners for over-prescribing pain medications.

Murray's father, Dr. Rawle Andrews, a well-respected Houston physician, now deceased, had his medical license restricted by the board in 1994 for prescribing "controlled substances and substances with addictive potential" to two patients for "extended periods of time without adequate indication," according to documents obtained by ABCNews.com.

In its report, the board singled out four "dangerous" drugs that it would be monitoring for a five-year period: stadol, a painkiller often used during labor; nubain, a painkiller similar to stadol; phenergan, a drug used to treat severe allergic reactions; and talwin, a potent painkiller often used as a supplement to anesthesia.

Investigators looking into Jackson's death believe that someone was intravenously administering propofol, a powerful sedative, to Jackson at his home.

Medical experts have soundly agreed that a drug like propofol, which is typically used in the hospital to sedate patients for surgery or other medical procedures, should not be used in the home.

Murray's lawyers have maintained for weeks that the doctor was simply a witness in Jackson's death and had nothing to do with it.
