FORT MYERS, Fla. - The texts that Roderic Gadson sent two female students are racy and suggestive.

Parents are reacting after the athletic director resigned his position at Fort Myers High School after only months on the job.

Someone showed the school principal text messages Gadon sent to two students at school. One says, "You are so hot. You make me smile when I look at you. Let us keep this a secret between us."

Child psychologist Keegan Culver says it's a textbook case.

"It's easy for them to get closer to kids to get to that grooming stage, that grooming process that they go through when they're selecting a victim," Culver said.

She says it's becoming even easier now through social networking for someone in a position of power to secretly seduce children without other children noticing. But it's also a good tool to catch a predator.

"There's  a good aspect to it. This information can become evidence to show to other people and theres something tangible about it," said Culver.

In this case, that's exactly what happened. Without these racy text messages, Gadson may never have been caught.
