Clue that led to arrests in case of slain Aussie brothers Jack and Callum Robinson in Mexico

A routine act on the side of the road led to the suspects for the murder of Australian surfers Jack and Callum Robinson, Mexican police have said.

The suspects accused of gunning down three surfers in Mexico, including two Australians, were reportedly tracked down when one was pulled over for a routine traffic stop.

Ari Gisel, 23, was busted in a routine patrol in Ensenada, 100km south of Tijuana, on May 1, during which she tossed a 100-gram bag of meth and tried to flee, Mexican news program Telediario reported.

Police then searched her car –– and found an iPhone that belonged to Jack Carter Rhoad, a 30-year-old American who was last seen in Ensenada with Western Australian brothers, brothers Jack and Callum Robinson, on April 27.

At the time of Ms Gisel’s arrest, investigators were already trying to trace Mr Rhoad’s phone when they noticed that someone had turned it back on, causing it to ping a nearby cell tower, an insider previously told US news website The Daily Beast.

Once detained, Ms Gisel told police her boyfriend, Jesús Gerardo Garcia Cota, had shown up at her home on April 28 and told her he did something to “three gringos,” according to the local reports.

When Ms Gisel asked her boyfriend what he meant, he allegedly confessed to killing the trio, report the New York Post.

Garcia Cota then brought his girlfriend out to his car, where he showed her the new tyres he allegedly took from the victims’ white Chevrolet Colorado car.

The bodies of the three men were discovered down a 15 metre well on early on May 3, when authorities said they were already investigating three people in connection with their deaths.

All three had been shot in the head, police said.

Ari Gisel García Cota, 23, is one of three charged over the disappearance of Australian surfers Callum and Jake Robinson and American Jack Carter Rhoad in Mexico.

A white pick-up truck matching the one the friends were driving was also found torched nearby.

One day later, on May 4, police announced that Gisel, Garcia Cota, and the latter’s brother, Cristian Alejandro Garcia, had been arrested.

Mexican prosecutors claim that the three surfers were killed when they tried to fend off the would-be robbers.
