Conrad Murray Says He Can Prove He Didn’t Kill Michael Jackson

Conrad Murray wants a key piece of evidence tested which his lawyers argue could prove Michael Jackson injected himself with the drug that killed him.
According to TMZ, Murray claims testing will prove there was NO lidocaine on the vial, because Jackson injected himself with a pure dose of Propofol, and killed himself.
The lidocaine is important because the prosecution argued that Murray hooked MJ up to an IV bag containing the fatal dose of propofol and left him alone, but first, mixed the Propofol with lidocaine to ease the sting of the drug.
Murray is serving a four-year prison sentence.
