Kris Kremers, 21 years old and Lisanne Froon, 22 years old were two Dutch students who traveled to Panama for a six week long holiday but mysteriously disappeared while hiking. Authorities have begun a search for the missing girls, so far no signs of them have been found.

Ten weeks later, a local woman found Lisanne's backpack which sends the search in a strange direction. According to the woman the backpack had not been there the day before and was in a surprisingly good condition which is strange when the girls have been lost for ten weeks. In the backpack the two girl's mobile phones and one camera was found. According to the phone data they had turned on and off the phones a number of times to try to call the alarm center and see if they had a signal but failed to reach. Then one phone has been switched on three times and an incorrect pin code has been attempted. On the camera 90 images were found taken with lightning in the middle of the night deep into the jungle 8 days after the girls disappeared. One of the pictures shows Kris's hair with something that looks like blood at the side of her head.

Two months later, in the same area as the backpack was found a pelvic bone, 33 skeletal bones and a boot with a foot inside were detected, which according to the DNA tests belonged to the girls. The skeleton bones that have been found have sent the investigation in another direction and caused more problems for the authorities. Lisanne's bones still had traces of tissue while Kris's bones had been bleached. According to an anthropologist the bones should not have been bleached after only nine weeks, but this may have been done by using some sort of bleaching to accelerate the decompose. Police have also found that a photo had been deleted off the camera which is unlikely the girls could have done. It is still unknown at this time what has happened to Kris Kremer and Lisanne Froon.
