Acquittal = Murder: Lt. Joe Novelli, Homicide 13

Katherine's acquitted for the murder of her and ex-husband, police officer Ray Collins, daughter Catlin. The next morning she's shot in the parking lot of the Springfield Inn in front of two police officers, but no one sees the shooter and a search of the area comes up empty, Lt. Joe Novelli investigates the murder of a woman who is despised in the town, blamed for a murder she was acquitted of. How many suspects can there be? But murder isn't the only crime that's been committed and the murder of one child becomes that of possibly three.
