Hampton says the man allegedly contacted his prey and told them he had nude photos of them that he would share online. He then allegedly blackmailed them into sending him nude images, even demanding they meet him at multiple parks in the Carmichael area, wherein one case detectives say he sexually assaulted a victim.

“I think it’s terrible they’re taking advantage of young people who are especially susceptible, especially on the internet,” said concerned citizen Carter Nelson.

Hampton said, “We do have identifications pending right now that if we did release his photo into the community or his name, there’s a potential that those people or victims or potential victims could be influenced by seeing his photo.”

Authorities say online predators are everywhere and the crimes are nothing new. They hope this latest case is another reminder for parents to pay close attention to their child’s internet activity.
