'Secret police file' could help acquit Dr Conrad Murray, it has been claimed

Traces of cocaine were found in Michael Jackson‘s underpants when the garments were seized during a search of his Neverland ranch in 2003, it has been claimed.

According to the News Of The World, a secret police document has revealed that toxicology tests on the Calvin Klein briefs showed traces of the substance, along with a “cocktail of other drugs”.

The file also alleges that 500 bottles of prescription medicine were found at the property during the raid, which was related to child molestation charges levelled at Jackson.

The ‘evidence’ is apparently going to be used at the trial of the singer’s doctor Conrad Murray, who is accused of causing Jackson‘s death in 2009.

Murray – who allegedly gave the singer a fatal jab of sedative Propofol – has pleaded not guilty to the involuntary manslaughter charge.

A ‘source’ close to the case told the newspaper: “There’s dockets are vital to Murray‘s defence. They help show the jury the depth of MJ‘s drug issues and how he may never have stood a chance of saving him.”

Last month, Judge Michael Pastor ruled that photographs from Michael Jackson’s autopsy could be used by prosecutors at the trial.

However, Murray‘s defence lawyers have been denied access to the late singer’s financial records, which they claim prove the self-styled King of Pop took “desperate measures” that led to his death.
