Grab a beer and join us tonight as we wrap up our two-part series on the 1982 Chicago Tylenol Murders. Tonight we're getting into the suspects, starting with James Lewis, the man who sent Johnson and Johnson an extortion letter demanding a million dollars to stop the killings and became the prime suspect for the next four decades. We'll walk through his criminal history, the other names investigators looked at, the DNA testing that should have closed the case but only made things more complicated, and why after forty plus years and one of the largest investigations in American history, nobody has ever been charged with a single one of these murders.
