I enjoy watching this. They don't do a reconstruction of the crime. Probably made during pandemic...not sure. People are interviewed one at a time either outside or totally alone inside. Courtroom scenes are totally empty courtrooms with a voice-over. This is more about the effect on the community, rather light on forensics considering the title. Liked the 30-yr old cold cases solved by familial DNA searches. Also interesting to hear what the original detectives looked for on the scene. And families interviewed about murderers found among their members. There is quite a bit of repeated scenes like swabbing blood stains on fabric that they used in multiple episodes. I was familiar with many of these crimes, but this was just enough of a different point of view that it was well worth watching.
