A group of Seattle teens were out exploring a remote beach when they made a gruesome discovery — a dead body inside of a suitcase. At first they had no idea what was inside, and joked about the foul odor coming from the bag. When police arrived they confirmed that a trash bag inside the suitcase contained human remains. The teens were directed to the location using "Randonautica,” an app that sends you to randomly selected coordinates to help you explore a city. We spoke to the app’s creator.
