Electronic-sniffing dog helps capture high-profile suspected pedophile in Mexico, ending international manhunt

An unusual alliance of international activist groups, Mexican prosecutors and a dog trained to sniff out memory devices joined forces this month to catch a high-profile suspected pedophile in Mexico City.

Free a Girl, a Netherlands-based group that fights human trafficking, tipped off activists at the U.S.-based Operation Underground Railroad that Jason Maatman, a Dutch man who openly advocated sex with children, had gone to Mexico after fleeing pending court cases in the Netherlands.

Maatman apparently thought loose Mexican law enforcement would allow him to operate freely in Mexico City, a sprawling metropolis of 21 million where most crimes go unpunished.
