Over the weekend, a train derailed in Southern Mexico killing at least six people and injuring dozens more. The victims were migrants from Central America, many of them riding on the roof or between the cars of the cargo train, known as "The Beast."
Each year, hundreds of thousands of migrants make their way from Central America through Mexico this way, hoping to eventually make it into the U.S. It's a harrowing journey and train crashes like this are just one of many dangers they encounter along the way.
Reporter Sonia Nazario traced the journey of a young man who made this trip for a Pulitzer Prize-winning series for the LA Times, known as "Enrique's Journey."
She later published a book by the same name and an adaptation of that book for young people is being released today.
