The Devil's Playground is a case featured in Criminal Case, appearing as the thirty-sixth case of the game as well as the city of Grimsborough. It takes place at the University, a district based in Grimsborough.
Chief King sent the player and Jones to the Amish community to collect the body of a Grimsborough University student named Tom Blackwater, who was found tied up like a scarecrow, seeping with blood. In the crime scene, Ramirez informed that an Amish kid named Isaac Hersberger witnessed the whole murder and was still in shock. They then started the murder investigation. Mid-investigation, to ensure that the police was not offending the Amish, Grace informed Chief King that she would tend for Isaac Hersberger during the investigation, while Nathan would do Grace's duties in her absence from the forensics lab. Grace wore Amish clothes in that case in order to show respect to the community. Jones also did not want to take any of the suspects to the interrogation room since he knew that doing this on an Amish would be disrespectful. The killer turned out to be an Amish farmer named Ezekiel Hersberger.
Tom wanted to buy Ezekiel's land for Dylan Cobbs and was also in love with Hannah Hersberger, Ezekiel's daughter. He wanted to take Hannah away from the Amish community, but Ezekiel could not let this happen as it was against the Amish rules to love a non-Amish. One day in the Amish farm, Ezekiel confronted Tom and the victim boasted about how much Hannah loved him and that she would choose him over Ezekiel any day. This angered Ezekiel a lot and he jumped on a horse and chased him with a pitchfork. Ezekiel strung up the victim like a scarecrow to symbolize that he wanted the non-Amish to stay away. Ezekiel called the outside world "The Devil's Playground" and hated the outside world. He wanted Tom's scarecrow death to symbolize outsiders to be scared.
