JEFFERSON COUNT, Colo. -- It's 3 p.m. in the middle of the week.

I asked Detective Mike Harris to get on his computer so I could get some video for my story on how prolific Internet predators have become.

At his desk in the Jefferson County District Attorney's Office he can log onto multiple chat rooms simultaneously, posing as a child.

Within minutes, he's chatting with several different men who think he's a 13-year-old boy or girl.

"Men fall in love with my persona," Harris said.

That's at 3 p.m.

Harris believes one out of every three or four children between the ages of 10 and 16 has had a conversation with or been approached by an adult online.

Many of those conversations, Harris says, are sexual in nature.

The Jefferson County District Attorney's Office recently arrested its 100th suspect in connection with Internet luring and attempted sexual assault on a child.

Harris says he could arrest 100 every six months if he had the staff.

"We're way behind the curve, way behind," he said.

District Attorney Scott Storey said he's committed more resources than any DA's office in the state to catching Internet predators.

"There are so many millions of people out there going after kids. We need everyone's help in alerting authorities," Storey said.

That means reporting any potential crime to your local police department.

Storey and Harris both admit their office is better-equipped to handle these types of complaints than most, so parents will need to be persistent.

Harris says nothing takes the place of open communication between parents and their children.

He says parents need to supervise their children's time online and make sure the computer is in a public place in the home, not in the child's bedroom.

If you suspect a predator has approached your child online, our experts say try to print out or preserve the conversation by copying it to a file. If you cannot do that, write it all down including any names, addresses or phone numbers in the text. Investigators will also need the exact screen name of the suspect, including underscores.

They say educated parent can do a lot more to protect their children from online crime.
