Mexican authorities have launched an investigation into the mysterious disappearance of two Australians and a San Diego man, who went missing while on a surfing trip in the Pacific coast state of Baja California over the weekend. The missing individuals have been identified as Jake and Callum Robinson from Australia, and Carter Rhoad from San Diego.

Debra Robinson, the mother of the Australian surfers, posted an appeal on a local community Facebook page, seeking help in locating her sons, as they had not been heard from since April 27. It was revealed that the three had planned to stay in Rosarito, Baja California, but failed to arrive at their intended accommodations.

Annie Wang, a friend of Jake Robinson, expressed concerns about their safety, especially considering Callum's condition as a type 1 diabetic. The three were last seen traveling in a white Chevy Colorado pick-up truck in Mexico.

The Baja California state attorney general's office announced on Thursday that they had located a white pick-up truck, which is currently being analyzed by forensic experts to determine if it is the same vehicle used by the missing individuals. Additionally, authorities discovered abandoned tents near the area where the three were last seen.

It was confirmed by FBI San Diego that three individuals were found dead in the town of Santo Tomas in the Ensenada Municipality of Baja California. However, there has been no official confirmation regarding the identity of these bodies.

María Elena Andrade Ramírez, the state's chief prosecutor, revealed that three individuals have been questioned in relation to the case, but did not specify whether they were considered as suspects or witnesses. She mentioned that evidence found near the abandoned tents was potentially linked to the missing surfers.

Authorities believe that the three foreigners were likely surfing and camping along the Baja coast near Ensenada. Andrade Ramírez emphasized that all lines of investigation are being pursued, including potential involvement of drug cartels in the area.

In a separate development, a woman in Ensenada was arrested for possessing illegal drugs, and it was discovered that she had a picture of one of the missing men on her phone.

Andrade Ramírez stated that her office is in contact with Australian and U.S. officials, but the time that has passed since the individuals were reported missing is making it more challenging to locate them. She urged the public to provide any potential leads or information that could aid in the investigation.

The incident is reminiscent of a similar case in 2015, where two Australian surfers were tragically killed in the western Sinaloa state. Those surfers fell victim to highway bandits, and three suspects were eventually arrested in connection with the crime.

As the search for Jake Robinson, Callum Robinson, and Carter Rhoad continues, authorities are urging anyone with information to come forward.
