(CNN) — A mysterious castaway claiming to have been lost at sea for 13 months is now safely back on land, but many questions remain about how he could have lived on his small boat for so long as it drifted across the Pacific Ocean.
The man calling himself Jose Ivan Alvarengo turned up in a heavily damaged boat on a remote coral atoll in the Marshall Islands, claiming that he had been living off fish and turtles he had caught and relying on rainwater, and sometimes his own urine, to drink.
Authorities are trying to determine the veracity of Alvarengo’s story.
He was found on sparsely populated Ebon Atoll, a 22-hour boat ride from the capital of Majuro, on Thursday. The southernmost of the Marshall Islands’ atolls, Ebon has only 2.2 square miles of land, one phone line and no Internet service. The government airplane that services the atoll was not working, so Alvarengo did not make it to Majuro until Monday morning.
Alvarengo, who says he is 37, is now in a local hospital recovering from his ordeal, said U.S. Ambassador Tom Armbruster.
In a hospital-bed interview with The Telegraph of London, Alvarengo told of how he hit land.
“I had just killed a bird to eat and saw some trees,” he is quoted as saying.
“I cried, ‘Oh, God.’ I got to land and had a mountain of sleep. In the morning, I woke up and heard a rooster and saw chickens and saw a small house. I saw two native women screaming and yelling. I didn’t have any clothes; I was only in my underwear, and they were ripped and torn,” The Telegraph quotes Alvarengo as saying.
People on the island where he was found Thursday say the 26-foot fiberglass boat was in very bad condition, covered in barnacles and with the carcasses of several turtles littering the deck.
Alvarengo claims to have set off from a port near the southwestern Mexican city of Tapachula, near the border with Guatemala, for what was supposed to be a one-day expedition to catch sharks on December 21, 2012.
He claimed that he and a teenage companion were blown off-course by northerly winds and then caught in a storm, eventually losing use of their engines.
According to Anjenette Kattil of the Marshall Islands Ministry of Foreign Affairs, Alvarengo said that four weeks into their drift, he lost the young man because he refused to eat raw birds. There are no details on what Alvarengo did with the young man’s body.
Alvarengo told the Telegraph his companion’s death had him contemplating suicide.
“For four days, I wanted to kill myself. But I couldn’t feel the desire; I didn’t want to feel the pain. I couldn’t do it,” he is quoted as saying.
Kattil said Alvarengo worked for a company named Camaroneras de la Costa in Mexico. He has told authorities that he is a citizen of El Salvador but has lived in Mexico for the past 15 years and wishes to be repatriated back to Mexico.
Government officials have been in contact with Mexico’s ambassador to the Marshall Islands, who is based in the Philippines, concerning Alvarengo in hopes he can contact El Salvadoran authorities.
The Mexican Ministry of Foreign Affairs issued a statement saying it has sent personnel from its embassy in the Philippines “to learn directly about the case.”
If Alvarengo’s story proves true, the trip across the Pacific would have taken him across roughly 5,000 miles (8,000 kilometers) of open ocean before ending in the Marshall Islands, about halfway between Hawaii and Australia, in the northern Pacific.
Such an amazing journey isn’t unheard-of in the small Pacific nation, as three Mexican fishermen made a similar drift voyage in 2006 that lasted nine months. Those men lived off fish they caught and rainwater, and they read the Bible for comfort.
Conditions in the Pacific make the timeline of Alvarengo’s journey plausible, according to Judson Jones, a producer for CNN Weather.
Jones said the currents between Mexico and the Marshall Islands would have carried a boat about 27 miles (42 kilometers) a day. That would mean the journey would take about 208 days if the boat stayed in the current. But Jones said a meandering journey in and out of the currents was most likely, making a 13-month journey believable.
