Conrad Murray -- Monday's the Day ... Finally

The L.A. County District Attorney just said the case against Dr. Conrad Murray in the death of Michael Jackson will be filed on Monday.

As we first reported, our sources say the D.A. will file involuntary manslaughter charges against the doc.

The D.A. says information on the charges and the arraignment at Airport Court will be released after charges are filed.

The D.A. did not say if Dr. Murray will be arrested or voluntarily surrender himself in court.
