Dr. Phil delves into a murder that happened 21 years ago. Rob Will was 22 when he was convicted of capital murder and sentenced to death 19 years ago for shooting and killing a 38-year-old Sheriff’s Deputy.

Both sides are talking: the prosecutor who says the right man is behind bars, and those who believe that ballistic evidence and the lack of DNA don’t lie.
