The First 48/YMMV

Alas, Poor Villain - The first victim talked about in the episode "Loose Ends" was apparently one of the perpetrators in a robbery that ended in murder. He was apparently killed by a fellow robber who was angry that he had failed to dispose of a cell phone that he had used to set up the robbery. They show pictures of the victim when he was younger and have his mother talk about how devastated she was by his death, how proud she was when he graduated from high school, how she always knew that he would stay at home with her even after his siblings moved out, and how distressed she was when she heard that he had himself been involved in committing a homicide.
Ensemble Darkhorse - Each viewer has their "favorite" detective: Joe Schillaci of Miami and Anthony Mullins and Caroline Mason of Memphis are among the most popular.
High Octane Nightmare Fuel: Even with the heavy blurring of the corpses, it's still terrifying to hear the terrified 9-1-1 calls, then see detectives walk into a room with a blurred out corpse, blood splatters on the walls, and descriptions of things like "she was stabbed 70 times! She fought with her attacker, as evidenced by this streak of blood here!"
Tear Jerker: Witnessing the reactions of family and friends of the victims can be quite heart-wrenching.
The Woobie - Kevin Ruggerio of Miami, dumped by his fiancee by his third episode... by telephone.
