A solid episode that ends with a bombshell. The bulk of the episode was around the idea that this kid created software that allows you to basically "print" a gun that can be used to fire real bullets. Of course, his invention ends up getting himself killed with the very gun he makes. That was Story A. Story B revolved around the mysterious person that gave away $1 Million each to 10 "random" people. Turns out that the 'Guardian Angel' is none other than Sid (Robert Joy). Turns out he gave away the money because those 10 people had family members that were connected to cases he had performed autopsies on. The bombshell is that he confides to Jo (Sela Ward) that he is dying of cancer. Very sad scene. I've always liked the character and the actor that portrays him. I like to see him saved and continue on with the show.
