LEE COUNTY, Fl. - One day after a major sex predator bust in Lee County, parents are demanding to know more about area educators. 

Of the 40 people arrested, two men were involved at Lee County schools.  Parents want to know, how to make sure their kids are safe but as WINK News explains, revealing someone's criminal intentions isn't as easy as you'd think.

"Very shocking!" says mother, April Ritter.

Forty men busted for looking online for sex with underage boys and girls.  One of them, a teacher at 19-year-old Cassie Harmon's Cape Coral high school.

"Being in that close of contact like that, that really freaks me out," Harmon says.

Her mom, April Ritter says she's wants to take action.

"They don't just come up with these feelings overnight... I want to know what we can do and how we can know that that's what's going on in these teachers and faculties minds," she says.

"We make it our business to find out their business," says Will Zariske with W & W Solutions Inc.

Will Zariske has worked as a private investigator for more than a decade.  He says they have their own ways of finding things out like comprehensive background checks but when it comes to predators who have never been caught before., that can make it tough.  Sites like Lee County's and FDLE's only shows them after an arrest has been made.

"If they don't want to be found or they've changed their name or there's some wrench they've thrown in there it can be difficult to find somebody if they're trying to really hide something," he says.

He adds being very involved in your child's life is a good way to start your own background check.

"Pay very close attention to what your children are involved in, the social networks that they're using ...ask your children how they feel about the teachers or the adults or anyone else in their life," he adds.

"She's told us that since day one that she doesn't feel comfortable there and now with this all coming out it kind of explains why," Ritter adds.
