The disappearance of two Australian brothers and one American tourist who vanished in Mexico has taken a tragic turn after their bodies were discovered in a well, alongside a fourth corpse that hasn't been identified.

Distraught relatives have identified three bodies found in a well as those of Jake and Callum Robinson and Jack Carter Rhoad, who went missing last weekend. Baja California state prosecutors said the relatives had viewed the corpses recovered from a remote well about 50 feet (15 meters) deep and recognized them as their loved ones.

Thieves apparently killed the three, who were on a surfing trip to Mexico’s Baja peninsula, to steal their truck because they wanted the tires. They then allegedly got rid of the bodies by dumping them in a well near the coast.

The well was located some four miles (six kilometers) from where the tourists were killed and also contained a fourth body that had been there much longer. Three suspects are being held in connection with the case, which locals said was solved far more quickly than the disappearances of thousands of Mexicans.

The three men were on a camping and surfing trip along a stretch of coast south of the city of Ensenada, posting idyllic photos on social media of waves and isolated beaches, before they went missing last weekend. Chief state prosecutor María Elena Andrade Ramírez described what likely would have been moments of terror that ended the trip for Jake, Callum and Jack.

She theorized the killers drove by and saw the foreigners’ pickup truck and tents and wanted to steal their tires. But “when (the foreigners) came up and caught them, surely, they resisted.” She said that’s when the killers would have shot the tourists.

The thieves then allegedly went to what she called “a site that is extremely hard to get to” and allegedly dumped the bodies into a well they apparently were familiar with. She said investigators were not ruling out the possibility the same suspects also dumped the first, earlier body in the well as part of previous crimes.

“They may have been looking for trucks in this area,” Andrade Ramírez said. The thieves allegedly covered the well with boards. “It was literally almost impossible to find it,” Andrade Ramírez said, and it took two hours to winch the bodies out of the well.

Australian Treasurer Jim Chalmers expressed sympathy for the Robinson family. “I think the whole country’s heart goes out to all of their loved ones. It has been an absolutely horrendous, absolutely horrific ordeal and our thoughts are with all of them today,” he said at a news conference Monday in the capital, Canberra.

The site where the bodies were discovered near the township of Santo Tomás was near the remote seaside area where the missing men’s tents and truck were found Thursday along the coast. From their last photo posts, the trip looked perfect. But even experienced local expatriates are questioning whether it is safe to camp along the largely deserted coast anymore.

The moderator of the local Talk Baja internet forum, who has lived in the area for almost two decades, wrote in an editorial Saturday that “the reality is, the dangers of traveling to and camping in remote areas are outweighing the benefits anymore.”

But in a way, adventure was key to the victims’ lifestyle. Callum’s Instagram account contained the following slogan: “If you’re not living on the edge, you’re taking up too much room.”

At the news conference, Andrade Ramírez was questioned by one reporter who expressed approval that such a massive and rapid search was mounted for the foreigners, but asked why, when local people disappear in the area, little is often done for weeks, months, or years.

“Do you have to be a foreigner in Baja California in order for there to be an investigation if something happens to you?′ asked the reporter, who did not identify herself by name. ”Every investigation is different,” Andrade Ramírez replied.

As if to underscore that point, dozens of mourners, surfers and demonstrators gathered in a main plaza in Ensenada, the nearest city, to voice their anger and sadness at the deaths. “Ensenada is a mass grave,” read one placard carried by protesters. “Australia, we are with you,” one man scrawled on one of the half-dozen surfboards at the demonstration.

A woman held up a sign that read “They only wanted to surf — we demand safe beaches.” Baja California prosecutors had said they were questioning three people in the killings, two of them because they were caught with methamphetamines.

Prosecutors said the two were being held pending drug charges but continue to be suspects in the killings. A third man was arrested on charges of a crime equivalent to kidnapping, but that was before the bodies were found. It was unclear if he might face more charges.

The third suspect was believed to have directly participated in the killings. In keeping with Mexican law, prosecutors identified him by his first name, Jesús Gerardo, alias “el Kekas,” a slang word that means “quesadillas,” or cheese tortillas. Andrade Ramírez said he had a criminal record, and that more people may have been involved.
