Watch: Mother of surfers slain in Mexico says ‘shine brighter’ in their memory

The mother of two Australian brothers killed in Mexico has said “the world has become a darker place”. Debra and Martin Robinson said their sons Callum, 33, and Jake, 30, had been "young men enjoying their passion" for surfing. They also mourned the loss of their sons' US friend, Jack Carter Rhoad, 30.

A Mexican man has been charged with "forced disappearance" and is expected to be charged with three murders.
