"Over the years, Griffith Park has been the final resting place for many a murder victim. In the 70s, it was the preferred dumping ground for the Hillside Strangler(s). Every year, police are called to the massive wilderness park when unlucky hikers stumble upon bodies. In this year alone, a woman's body was dumped in the park and found wrapped in blankets, a man's body was found in a park restroom, and another man's body was discovered near a high-voltage transmission tower in the park."
