EXCLUSIVEDr. Conrad Murray mocked the 5-year anniversary of Michael Jackson's death by popping into a convenience store for a bottle of milk.
In case you don't remember, Michael's code word for Propofol -- the drug that killed him -- was milk.
Murray has commemorated June 25th in various ways ... having his pic snapped in a tearful pose at MJ's mausoleum, dancing at a wedding and various other hijinks.
This is Murray's first MJ anniversary since being sprung from L.A. County Jail.
