 When police ran X-ray scanners over two cargo trucks at a checkpoint in southeastern Mexico on Tuesday, they made a surprising discovery: Inside the trailer were the ghostly shadows of 513 migrants — some suffering from dehydration — packed together in near-suffocating conditions. An agent for the National Immigration Institute who was not authorized to be quoted by name said it was the largest shipment of migrants detained in Mexico in recent years.
– Mexican police saw something shocking when they aimed their X-ray scanners at a pair of tractor trailers at a checkpoint in Chiapas. The trucks were jammed full of 513 illegal migrants, many of them suffering from dehydration, the AP reports. Though air holes had been cut in the top of the trucks, the migrants said they felt suffocated as well. “We were suffering,” one said. “It was very hot, and we were clinging to the ropes.” The migrants hailed from throughout South America, Central America, and even Asia, and were bound for the US. Some said they were charged around $7,000 for the trip. Mexican authorities say it was their largest migrant smuggling bust in years. The type of scanner that spotted the migrants was, interestingly enough, similar to the devices so reviled by airline passengers, the New York Times notes.
