Two men waiting in ambush machine-gunned to death the publisher and star reporter of a Mexican newspaper that has taken a strong stand against corruption and drug smuggling in the border city of Matamoros, police said. Ernesto Flores Torrijos, 46, publisher of El Popular, and reporter Norma Moreno Figueroa, 24, were shot as they stepped from their car in front of their office in Matamoros, across the Rio Grande from Brownsville, Tex. Witnesses said dozens of shots were fired. Police said they have no suspects. It was the second time in a month that crusading Mexican journalists have been murdered in the border state of Tamaulipas.
