TWO of the four American citizens kidnapped in Mexico on Friday are dead, Mexican authorities have revealed. One of the victims was found alive, while the fourth is injured in unknown condition, Tamaulipas State Governor Américo Villarreal said on Tuesday. President Lopez Obrador vowed those responsible will be "punished." They were in a white minivan with North Carolina license plates when they came under fire, the US Embassy in Mexico City said on Sunday. President Lopez Obrador grumbled about the US media’s coverage of the missing Americans, accusing them of sensationalizing things.
