LONDON - Officials investigating the death of Michael Jackson were on the lookout for evidence that the star was murdered by his personal doctor when they searched the medic’s clinic.

Officials were given a search warrant, indicating that Jackson’s doctor, Conrad Murray, was the target of a manslaughter probe into the singer’s death.

Detectives, joined by Drug Enforcement Agency officers, searched the doctor’s clinic and storage unit to look for “items constituting evidence of the offence of manslaughter that tend to show that Dr. Conrad Murray committed said criminal offence”, reports The Sun.

The team apparently seized vials, receipts and a computer during the raid on the expert’s offices in Houston, Texas.

Meanwhile, a source said the coroner’s verdict on Jackson’s cause of death would “almost certainly” be homicide.

The source said: “We are told the coroner himself will make the call mid-week after he gets the final toxicology report from an outside consultant.

“But based on the draft report, as well as what has become ‘clear evidence’, causes other than homicide - natural, accidental, accidental overdose, and suicide - have been ruled out.”

The Jackson family recently alleged that they were convinced that the King of Pop may have been left to die after being injected with Propofol sedative.

Ed Chernoff, the lawyer for Murray insisted the medic did not administer any drug that contributed to the Jackson’s death.

Chernoff, however, declined to comment if Murray injected Jackson with Propofol. (ANI)
