could secure the country. Instead of waiting in the harbor as they were instructed, Thompson and his crew killed the viceroy's men and sailed to Cocos, where they allegedly buried the treasure. Shortly afterwards, they were apprehended by a Spanish warship. All of the crew except Thompson and his first mate were executed for piracy. The two said they would show the Spaniards where they had hidden the treasure in return for their lives, but after landing on Cocos, they escaped into the forest and were never recaptured. Hundreds of attempts to find treasure on the island have failed. Several early expeditions were mounted on the basis of claims by a man named Keating, who was supposed to have befriended Thompson. On one trip, Keating was said to have retrieved gold and jewels from the treasure.MacInnis, pp. 29–30. German adventurer

and other seafood is threatening the island's fragile ecosystems. The government of Costa Rica has been openly accused of passivity and even benefiting corruptly from illegal shark fin and other seafood trade to large markets, such as China and other Asian countries. The government has shown some willingness to protect the island's natural riches and prosecute poachers. However, efforts to effectively patrol the waters and enforce environmental laws face big financial and bureaucratic difficulties, as well as being prone to the corruption of local, national and international authorities. Recent events show that large-scale illegal poaching keeps happening. Despite initial hope in stopping and charging poachers, who have been caught with abundant evidence, they have often been quickly released under suspicious circumstances. Also, efforts to raise funds for protection have been dwarfed. Marvin Orlando Cerdas, a judge with the local Puntarenas Court of Justice, obscurely allowed 22 poachers caught red-handed to escape the country. Also under highly suspicious and allegedly corrupt circumstances, District Attorney Michael Morales Molina stopped the auction for public benefit of confiscated goods immediately after the spokesman of the large illegal poaching ship ''Tiuna'' simply made the request.
