Spanish authorities have located a missing American hiker’s body and suspect he fell down a mountain, according to local media.

Guilford Cole Henderson plummeted approximately 650 feet down a mountain in a secluded area in Spain while hiking in the Ordesa y Monte Perdido National Park in the Pyrenees, according to local newspapers El Espaniol and El Diario De Huesca. This region is on the boundary between France and Spain.

Authorities said his body was found on Friday.

Henderson was supposed to return home to the Netherlands on July 12, which caused the Spanish Civil Guard to launch a rescue effort. 

NBC News reported Henderson had parked his car in Torla, which is near the area he went hiking.
