TUXTLA GUTIERREZ, Mexico (AP) — A cargo truck jammed with people who appeared to be Central American migrants rolled over and crashed into a pedestrian bridge over on a highway in southern Mexico on Thursday, killing at least 49 people and injuring nearly five dozen others, authorities reported.
Luis Manuel Moreno, the head of the Chiapas state civil defense office, said a preliminary estimate listed 49 dead and 58 injured. He said about 21 of the injured had serious wounds and were taken to local hospitals.
The crash occurred on a highway leading toward the Chiapas state capital. Photos from the scene showed victims strewn across the pavement and inside the truck’s freight compartment.
Later, rescue workers arranged the dead in rows of white plastic body bags, side by side, on the asphalt.
The victims appeared to be immigrants from Central America, though their nationalities had not yet been confirmed. Moreno reported that some of the survivors said they were from the neighboring country of Guatemala.
Moreno said that it appeared that speed and sheer weight of the truck’s human cargo may have caused it to tip over, and that as the vehicle toppled over it hit the base of a steel pedestrian bridge. There was a curve in the road near the accident scene that may have contributed to the crash.
That meant at least 107 people were crowed into the vehicle. It is not unusual for freight trucks in Mexico to be carrying so many people in migrant-smuggling operations in southern Mexico.
Rescue workers who first arrived at the scene and who were not authorized to be quoted by name said that even more migrants had been aboard the truck when it crashed and had fled for fear of being detained by immigration agents.
One paramedic said some of those who fled into surrounding neighborhoods were bloodied or bruised, but still limped away in their desperation to escape.
The truck had originally been a closed freight module of the kind used to transport perishable goods. The container was smashed open by the force of the impact. It was unclear if the driver survived.
Those who spoke to survivors said the migrants told of boarding the truck in Mexico, near the border with Guatemala, and of paying between $2,500 and $3,500 to be transported to Mexico’s central state of Puebla. Once there, they would presumably have contracted with another set of migrant smugglers to take them to the U.S. border.
In recent months, Mexican authorities have tried to block migrants from walking in large groups toward the U.S. border, but the clandestine and illicit flow of migrant smuggling has continued.
In October, in one of the largest busts in recent memory, authorities in the northern border state of Tamaulipas found an 652 mainly Central American migrants jammed into a convoy of six freight trucks heading toward the U.S. border.
Irineo Mujica, an activist who is leading a march of a couple of hundred migrants who have been walking for more almost 1 1/2 months across southern Mexico, blamed Mexico’s policies of cracking down on migrant caravans for the disaster.
Mujica and his group had almost reached the outskirts of Mexico City on Thursday, after weeks of dealing with National Guard officers who tried to block the march. Mujica said the group would stop Thursday and offer prayers for the dead migrants.
"These policies that kill us, that murder us, is what leads to this type of tragedy," Mujica said.
In fact, they are two very different groups. Caravans generally attract migrants who don’t have the thousands of dollars needed to pay migrant smugglers.
Migrants involved in serious accidents are often allowed to stay in Mexico at least temporarily because they are considered witnesses to and victims of a crime, and later Thursday Mexico’s National Immigration Institute said it would offer the humanitarian visas to the survivors.
The agency also said the Mexican government would help identify the dead and cover funeral costs or repatriation of their remains.
Mass deaths of migrants are something that President Andrés Manuel López Obrador has been desperate to avoid, even as his administration has accepted requests from the U.S. government to stem the flow of migrants moving north.
It was one of the worst single-day death tolls for migrants in Mexico since the 2010 massacre of 72 migrants by the Zetas drug cartel in the northern state of Tamaulipas.
