Friends of Aussie brothers Jake and Callum Robinson have paid tribute to the “beautiful human beings” after they were confirmed dead by their parents yesterday, alongside their American friend Jack Carter Rhoad. Jake – a doctor who was about to start working at a hospital in Geelong – was remembered for his “smile”, “laugh” and “kindness”. Emily Horwath, the girlfriend of Callum – a professional Lacrosse player – said her heart was “shattered into a million pieces”. And the brothers’ parents, Debra and Martin, said their only comfort “is that they were together doing something they passionately love”. Meanwhile, Mexican authorities have given more details about the murders – they said their “preliminary theory” is that the trio were shot by thieves trying to steal their ute’s tyres. Locals in Ensenada, near where the men were killed, have also gathered to mourn their deaths.
