In Mexico, authorities have identified the remains of nine other victims — all Guatemalan — who were among 19 people killed in a massacre in the northern state of Tamaulipas. Of the 16 victims identified so far, two were Mexican and 14 Guatemalan. The 19 bodies were found shot and charred in a town near the U.S.-Mexico border in January. A dozen Mexican state police were arrested last week for their possible involvement in the massacre.
