Kris Kremers Lisanne Froon — Night Photos Updated

The most famous photo (#580) shows the back of Kris’s head, her hair matted with what looks like mud or blood, with a rocky cliff behind her. The old theory: They were stuck on a riverbed.

The Update: Digital elevation mapping now suggests that "cliff" is actually a vertical drop. The angle of the flash—casting shadows upward—proves the camera was at the bottom of a deep crevice or ravine. They weren't standing on a rock. They were looking up at the wall they fell down.

On April 1, Kris and Lisanne left their host family in Boquete to walk the El Pianista trail. This was a moderate hike leading into the continental divide. They were only carrying a small bag, a water bottle, Kris’s iPhone 4, Lisanne’s Samsung Galaxy S3, and a cheap Canon SX270 HS camera. kris kremers lisanne froon night photos updated

They never returned.

After a massive search, their backpack was found 10 weeks later on a riverbank far from the trail. Inside were two brassieres, a water bottle, Lisanne’s passport, $83 in cash, and the digital camera. The most famous photo (#580) shows the back

The camera’s memory card provided the only visual record of their disappearance. It contained 90 flash photographs taken between 1:00 AM and 4:00 AM on April 8—the so-called "night photos."

The night photos are not evidence of murder. They are evidence of a slow, terrifying tragedy. The final updated theory: Kris and Lisanne survived 8 days

The final updated theory: Kris and Lisanne survived 8 days. They suffered injuries on day 1 (Kris’s foot? Lisanne’s hand?) that prevented them from climbing out of the river gorge. By April 8, they were severely dehydrated, disoriented, and panicked. The night photos were a final, frantic attempt to attract attention, document their location, or simply to keep their minds busy in the hours before they succumbed.

The photo of the back of a head (likely Kris) was long considered proof of a third party holding the hair. However, updated flash analysis shows the angle of the shadow. The light source (camera flash) is low, pointing slightly upward.

New calculations indicate the camera was held at hip height by someone sitting or lying down on the wet rock. If a third party was holding the hair, the shadow would cast downward. It does not. The leading theory now: Lisanne, exhausted and possibly injured, was sitting against a rock, holding the camera below her waist, accidentally photographing Kris’s hair as she leaned forward to check a wound.
