Callum and Jake Robinson: Shock theory emerges about the Aussie brothers killed ... trends now
A shocking new theory about the execution-style deaths of two Australian brothers and their American friend has raised fears over the possible involvement of drug cartels.
Callum and Jake Robinson and their American mate Jack Carter Rhoad were last seen on April 27 in the Mexican province of Baja California.
Mexican authorities said bandits attacked the three to steal the tyres off their truck before killing them all and dumping their bodies in a disused well.
But the style of the slayings - a single gunshot to the head - has sparked fears locally about the possible involvement of drug cartels, which are rife in the region.
The shock new details emerged as Callum and Jake's grieving parents performed the grim task of identifying their bodies on Sunday.

Three Mexicans have already been arrested over the deaths but authorities are not ruling out further accomplices with possible links to organised crime.
'We cannot rule out the possibility that there are additional individuals who were involved in this incident,' local Attorney-General María Andrade Ramírez said.
She added that the victims 'all have a hole in their head made by a firearm projectile'.
Hundreds of people marched through the nearby town of Ensenada on Sunday afternoon, demanding greater security measures amid a welter of cartel-fuelled violence.
Some held surfboards emblazoned with messages written in Spanish, including 'Australia, we are with you' and 'They only wanted to surf, and they executed them', according to the ABC.
Baja California is one of Mexico's most violent states, with the US State Department advising Americans to reconsider travel to the state due to crime and kidnapping.
However, Ensanada is considered safer.
The Baja California Forensic Medical Service released the autopsy results as heartbreaking footage emerged of the Aussies' parents leaving the forensics lab after identifying Jake and Jake's bodies.

Daily Mail Australia previously revealed that Callum's devastated girlfriend Emily Horwath shared a heartfelt tribute on social media.
'You are one of one,' she wrote alongside a photograph of the couple sharing a kiss. 'I will love you forever.'
She also posted an Instagram story which said: 'My heart is shattered into a million pieces, I don't have the words right now.'
'This world lost one of its kindest, silliest and most genuine of souls this week. Rest easy. I miss you.'
