The 19-year-old has been missing for almost two weeks.
The last sign of life was on June 17, when he called a friend and said he was “lost and thirsty.” According to the friend, he must have sounded desperate during the conversation.
His phone was last traced to the Rural de Teno National Park in the north of the island.
Helicopters, drones and search dogs have unsuccessfully searched for the 19-year-old for several days.
