Three suspects have been detained in connection with the presumed killing of two Australian tourists who went missing last month, prosecutors in Mexico's Sinaloa state said Friday, AP reported. State prosecutor Marco Antonio Higuera said the three men were robbing motorists on a stretch of highway leading south through Navolato, Sinaloa. He said two other suspected members of the robbery gang remained at large. The three were arrested on low-level drug-dealing and weapons charges, but Higuera said he expects homicide charges to be filed against them soon. -- SPA 01:55 LOCAL TIME 22:55 GMT تغريد
