The men came from different walks of life on two continents: a children's puppeteer in Florida, a hotel manager in Massachusetts, an emergency medical technician in Kansas, a day care worker in the Netherlands. 

In all, 43 men have been arrested over the past two years in a horrific, far-flung child porn network that unraveled once a key clue was spotted.

In this case, the clue was a stuffed toy bunny.

The bunny, seen in a photo of a half-naked, distraught 18-month-old boy, was used to painstakingly trace a molester to Amsterdam. From there, investigators made one arrest after another of men accused of sexually abusing children, exchanging explicit photos of the attacks and even chatting online about abducting, cooking and eating youngsters.

Authorities have identified more than 140 young victims so far and say there is no end in sight as they pore through hundreds of thousands of images found on the suspects' computers.
