Kris Kremers and Lisanne Froon were Dutch students who disappeared on 1st April 2014, while hiking the El Pianista trail in Panama. After an extensive search, portions of their bodies were found a few months later. Their cause of death could not be determined definitively, but Dutch authorities working with forensic and search-rescue investigators initially thought it likely the students had accidentally fallen from a cliff or river bridge after becoming lost. However, foul play could not be entirely ruled out, and is considered by some much more likely due to other remains being found. The circumstances and aftermath of their disappearance have resulted in much speculation about their final days.

Investigative journalist Mick Rooney examines the case circumstances, timeline and what is most plausible.
