Families of men presumed to be two Australians and American who went missing in Baja California arrive in Tijuana to identify bodies

The bodies believed to be those of the two Australians and an American who went missing in the Pacific coast state of Baja California showed the three men were killed with gunshots to the head, Mexican authorities said on Sunday.

María Elena Andrade Ramírez, the state’s attorney general, said the families of the missing men had arrived in Tijuana to verbally identify the bodies. Authorities expected to have official confirmation shortly.

Callum and Jake Robinson, both in their 30s, were Australian siblings from Perth. Jake was visiting Callum, who lived in San Diego, California, for a planned surfing holiday, with their friend Jack Carter Rhoad, a US citizen who also lived in San Diego. The trio were reported missing when they failed to check in to pre-arranged accommodation in Rosarito, Mexico, last weekend.

The bodies were found dumped in a remote well about 15m deep, about 6km from the camping site where the foreigners were killed. If relatives could not identify the bodies, genetic tests would be conducted.
