Body part with a distinctive tattoo found in shark's stomach helps solve the mystery of a missing quad biker

• The body parts of a missing man in Argentina were found inside a shark.
• His family identified the father of three, Diego Barría, by a distinctive tattoo.

The remains of a missing man in Argentina have been found in the stomach of a shark, AP reports.

Lead search officer Daniela Millatruz said that his family was able to confirm that it was the father of three "due to a tattoo that appeared in one of those remains," per AP.

Body parts of 32-year-old Diego Barría were found when two fishermen caught a 4.9-foot school shark in the southern Chubut, in Patagonian Argentina, last weekend. The school shark is hunted for its flesh, its fins, and its liver, which has a very high vitamin A content.

They were gutting their large catch when they made the grim discovery.

A WhatsApp audio message sent by one of the fishermen to a cousin was published by local media outlets, reported the Buenos Aires Times.

"I was so unlucky that I found him inside a shark. I went fishing, and I opened the shark's belly and found a forearm with a tattoo. We picked things up and went to the authorities, and it was him," said an excerpt. "He had a rose on his forearm that said 'Josefina,'" said the unnamed individual.

Barría had been missing since February 18, when he was last seen riding his quad bike, AP reports.

The vehicle was found abandoned and damaged on a beach near Rocas Coloradas on February 20, but there was no sign of Barría, despite an intense search, including drones.

Officials are still not clear on what happened to Barría but believe he "had an accident and was dragged," possibly unconscious, into the ocean, Millatruz said. There had been a strong tidal surge the weekend when he disappeared, said a police official, per AP.

Virginia Brugger, identified as Barría's partner and had been posting updates on the search on social media, wrote Sunday on Facebook, "My heart went out with you! I love you forever."

The remains found in the shark's stomach will undergo DNA analysis to officially confirm they belong to Barrìa, AP reported.
