Jimmy looked at the file and based on the timing, it was a case just received by the FBI that hadn't yet been assigned to anyone. His arrival was timely, taking on the case to investigate; moreover, it was one of those cases involving a body found years ago in the wilderness, likely to be another headless case.
The biggest trouble was, upon seeing Big Bend National Park, Jimmy couldn't help but recall what Roland had once said. Roland had taken Jimmy to Big Bend National Park, killed a demon, closed a rift, and then Jimmy had killed the people at the scene who were infected by the demon, and afterward left Roland to wander on his own.
Now looking at the file, Big Bend National Park, a cave, dozens of bullet holes, six dead people, death dating back 3-4 years. Excluding the absence of a demon, it was eerily similar to Roland's account. Jimmy felt chills down his spine. Could this cursed place be where he and Roland had killed a demon?
