A trio of bandits who allegedly killed three men on a surfing trip in Mexico had targeted the victims’ truck so they could take its tires, prosecutors revealed Sunday.

The Baja California Prosecutor’s Office released more grisly details in the murders of Australian brothers Jake, 30, and Callum Robinson, 33, and American Jack Carter Rhoad, 30, who were last seen alive on April 27 during a trip in the city of Ensenada.

The bodies of the three surfers found last week were positively identified Sunday by their families, Baja California state prosecutors said Sunday.

Chief state prosecutor Maria Elena Andrade Ramirez said during a press conference that the alleged killers decided to target the surfers when they noticed their truck and tents.
