The twelve men and women of the jury have begun deliberations. Their decision can come as soon as today or could take weeks to decide.

During closing arguments on Thursday, defense attorney Ed Chernoff said the prosecution "absolutely failed to prove a crime."

In comparison, prosecuting attorney David Walgren referred to the defense's theory as "junk science."

Dr. Murray is accused of injecting the King of Pop with a lethal dose of Propofol on June 25, 2009, resulting in Jackson's death.
