   Michael Jackson probably died after he rapidly injected himself with a dose of the surgical anesthetic propofol on top of a large dose of sedatives he swallowed when Dr. Conrad Murray was away, the defense’s propofol expert testified Friday. […] White also concluded that Jackson swallowed a large dose of lorazepam several hours earlier, which would have left "a very high concentration" of the sedative in his body.
