Dr. Conrad Murray, personal physician for Michael Jackson, speaks in a video posted on YouTube by his attorneys August 18, 2009. Murray states in his first public statement since Jackson died June 25, "I have told the truth and the truth will prevail."

BEIJING, Feb. 8 (Xinhuanet) -- The Los Angeles County district attorney's office will file charges against Dr. Conrad Murray on Monday, according to media reports Monday.

The charge will cap an eight-month police investigation into Michael Jackson's death and end days of intense speculation about when the singer's personal physician would be charged.

Lawyers for Dr. Murray want to use footages of a spaced-out Jackson to demonstrate the depth of his drug habit, News of the World reported.

“Murray’s legal team have quietly but steadily been building a robust defence case. A key element will be on-camera interviews Michael Jackson gave where he discusses and admits his drug use and others where he appears to be intoxicated,”said a legal source close to Dr. Murray.

Prosecutors originally planned to file the case Friday, according to law enforcement sources, who said the case was delayed after a dispute arose with Murray's defense team Thursday over the details of his surrender.

Murray was with Jackson the morning he died and admitted to investigators that he gave the 50-year-old pop singer sedatives and the powerful anesthetic drug propofol, which medical experts say should only be given in a hospital by trained personnel.

Murray told police that the singer had a long history of using the drug to sleep and he was trying to wean Jackson from it the week he died.

An autopsy classified Jackson's death as a homicide and said the cause was "acute propofol intoxication" in combination with the use of sedatives.
