That one is actually worse because the police were approached by (low status) victims so many times and didn't believe them.
Jamelske at least released his victims, thank God. The David Parker Rays and the Marc Dutrouxs of the world killed some or most of their victims, and I suspect that Ariel Castro has killed a few earlier victims as well. People who do this enjoy doing it, and they will take victims again if they are not stopped. All three of the Castro brothers, if convicted, should lose their right to life and be executed for this.
