[PREVIEW] #47: The Delphi Murders

On February 13, 2017, an unusually warm winter day provided a perfect backdrop for an impromptu hike, particularly since Delphi Community Middle School in Indiana had canceled classes that Monday to balance out unused snow days. The morning began leisurely for fourteen-year-old Liberty "Libby" German and her best friend, thirteen-year-old Abigail "Abby" Williams, who were recovering from a Sunday night sleepover at Libby's home. The evening prior, the girls had stayed up late eating pizza and garlic knots, watching a scary movie, and messaging boys on social media. When they finally woke up, Libby's father, Derrick, prepared them a breakfast of banana pancakes.Libby's grandmother, Becky Patty, was working in her home appraisal office located in the family's garage when the girls asked for permission to go to a hike at the trails. Although Libby did not mention her specific intention to cross the towering Monon High Bridge, Becky agreed to the outing, stipulating only that the girls needed reliable transportation to and from the hiking spot.Libby secured a ride from her sister, Kelsi. And her father, Derrick, agreed to pick the girls up two hours later.As the teenagers scrambled to leave, Becky reminded her granddaughter that despite the sunshine, the February air would still be chilly and she needed to take a jacket. Pausing in the doorframe, Libby offered her grandmother a final reassurance, stating, "Grandma, it'll be okay". The girls piled into Kelsi's car equipped for the weather; Libby brought along her new black swim team sweatshirt, and Kelsi loaned Abby a gray sweatshirt. With the song "Heathens" by Twenty One Pilots droning on the radio, Libby snapped a selfie in the backseat. At 1:38 P.M., Kelsi pulled up to the Mears entrance of the trails, where Abby and Libby jumped out of the car and disappeared into the trees.
