"US TOURISTS ROUT MUGGERS IN COSTA RICA
A cruise tour group of U.S. senior citizens fought muggers in eastern Costa Rica, sending two of them fleeing and killing a third, Limon Police Chief Luis Hernandez said. He said a retired Marine estimated to be in his 70s put one of the assailants in a headlock and broke his neck. Hernandez declined to give he names or hometowns of the tourists. He said they had a right to defend themselves and were allowed to leave."
