Mexican state a dangerous battleground for cartels
It took Mexican authorities more than three weeks using DNA samples sent by Guatemalan families to identify 18 of the 19 burned bodies – 16 Guatemalans and two Mexican men who smuggled migrants.
One remaining body was so badly burned that the forensic specialists haven't been able to identify it.
The location where authorities suspect the deaths occurred is one of the most dangerous states in Mexico.
Pressed against Texas' southern border along the Gulf of Mexico, Tamaulipas is the shortest route for migrants to the United States. But it also serves as a battleground between Mexican cartels.
