Dateline

The first in the series aired in November 2004 as a Dateline NBC segment called Dangerous Web. The operation was set up in a home in Long Island, NY, to which 18 men came over two-and-a-half days after making an appointment for sex with a minor. One of the men in the investigation was a New York City firefighter, who was later fired by the FDNY.

Predators scouring the Internet, targeting children for sex: It's a national problem that Dateline has helped uncover. We got such an overwhelming response from our last investigation— some 15,000 emails from parents, grandparents, teachers and law enforcement— telling us to "keep up the good work," and "keep the issue alive." On Wednesday night, April 26, Dateline is back with the fourth undercover investigation. This time, we traveled to small town America. Even far from the big cities and suburbs, vulnerable young teens are not far from danger. A warning: some of what you're about to see is explicit.

This report airs May 17, Wednesday, 9 p.m.: This month, millions of people have been watching our investigations into computer sex predators — among them, some of the suspected predators themselves. And what's most surprising is that even knowing that they may be walking into a sting is not enough to keep some of them away. Tonight, we're back in Florida, where we started our investigation last week. We want to remind you that some of what you'll see and read is explicit.

Like moths to the flame, they just keep coming. It's been more than two years now since we first began our series of reports investigating online sex predators. Five different states... 129 men exposed. On Dateline Wednesday, investigation number six. This time, we've set up our hidden cameras in a rented house in rural Georgia. And once again, even men who've seen our reports show up at the door. We should let you know, some of what you'll see and read below is explicit. This report first aired on NBC, Sept. 13.

In community after community, vulnerable young teenagers are still at risk from grown men online. On Sept. 22, Friday, our hidden cameras are in Georgia. This time among the suspected predators caught on tape are three military men — two served in Iraq. Now they could be serving time in prison. Again, we want to warn you, some of what you'll see is explicit.

It's what prompted our entire series of predator investigations: Grown men sending graphic e-mails to young teenagers. And now, it's what has forced a powerful congressman out of office in the scandal that's consuming Washington. Representative Mark Foley of Florida is accused of having sexually explicit online chats with underage teens. Dateline's latest investigation also uncovers some prominent men caught in what police say are criminal acts. They, too, risk losing their jobs... and in some cases, perhaps even their freedom. Again, we want to warn you that some of what you’re about to see is explicit. This report airs Friday, Oct. 6.

It's our twelfth "To Catch A Predator" investigation and this time we're set up in a 6,000- square foot home in Bowling Green, Kentucky. It's a town of about 50,000 people an hour north of Nashville, Tennessee. Each one of these investigations has its own rhythm and Kentucky is no different. Within hours I am struck by the fact that fewer men are showing up at our hidden camera house than in past investigations. Looking back I think this at least partially because the Kentucky Attorney General's office and the Kentucky Bureau of Investigation, along with local law enforcement, have been actively pursuing online predators in the past year. Before Dateline's investigation in Bowling Green, the Attorney General's office with the help of the online watchdog group Perverted Justice had conducted two previous sting operations without us, making 20 arrests. One of them was a 59-year old criminal justice instructor at an Ohio college who used to be an elementary school teacher.

A rare look at the frightening power of a charismatic killer, just 18 years old -- a teenage mastermind who convinces other kids to kill.

A Day At The Beach The fascinating Chris Hansen Dateline undercover sting series continues with new episodes. Tonight, in a multimillion dollar home on a beach in New Jersey, predators are still pursuing underage children and Perverted Justice volunteers are still pursuing them.
