Legal Update: Was Conrad Murray attempting a cover up?

Day three of testimony in the manslaughter trial of former Michael Jackson doctor Conrad Murray.

Most of the testimony in the Conrad Murray trial on Thursday was by security guard Alberto Alvarez, an eyewitness to Murray's frantic attempts to revive the singer in his bedroom. Alvarez recounts Murray tell him to wrap up the drug vials around Jackson's death bed before a call we even made to 9-1-1.
