There is a copycat killer on the loose in Ohio. This person is imitating the crimes of an executed serial killer known as 'The Angel Maker' who raped and murdered women as well as leaving oddly shaped puncture wounds in their stomachs.
On the anniversary of the execution of the killer, the crimes start again. The BAU are called in and realise that they are dealing with a copycat who is just as deadly as the original. The big twist (and the major problem) for the team is that semen samples recovered from the victims match exactly those of the dead killer. How is this possible? Could it be that the rumours that the execution of the killer was botched are actually true and that he has survived and is killing again or is there some other more sinister explanation for what has occurred?
Terrific episode with enough twists to satisfy we viewers who enjoy this show so much.
