Kris Kremers and Lisanne Froon — Dutch Tourists Vanish on Jungle Trail in Panama

On April 1, 2014, Dutch students Kris Kremers and Lisanne Froon disappeared while hiking the El Pianista trail near Boquete in the Chiriquí Highlands of Panama. They had been in Boquete for a Spanish language program and set off on a hike from which they never returned. Ten weeks later, a local woman found a bag containing the girls' belongings near a river—including their passports, $80 cash, a camera, and Lisanne's phone. The camera contained photographs from their hike that showed normal tourist images up until approximately 1 PM, followed by 90 photographs taken in complete darkness between 1 and 4 AM on the night they went missing, suggesting they were still alive but in distress hours after disappearing from the trail. In the days following their disappearance, Lisanne had made multiple emergency calls on her phone—including calls to 112, the Dutch emergency number—that connected but were not answered due to the lack of signal. The calls continued over several days. Bones later recovered from the area were identified as belonging to both young women, but the manner of their deaths could not be determined. No signs of violence were found on the remains. The photographs taken in darkness, the emergency calls, and the location where the bag was found—downstream from where the trail becomes dangerous—have never been fully explained.
