CANADIAN COUNTY, Oklahoma - The Canadian County Sheriff's Office took down three alleged child predators in a week.

Investigators said they tricked two of the men by posing as a young girl online. However, they said the third arrest proves some sexual predators are not caught in time.

“It just seems like the last three weeks, we did six one week, three one week, and two one week,” said Lt. Adam Flowers with the Canadian County Sheriff's Office.

The latest undercover sting landed 24-year-old Terry Erwin of Midwest City and 27-year-old Kyle Maxwell of Bethany behind bars.

Investigators said Erwin used Facebook and thought he was contacting a 14-year-old girl for sexual purposes. Maxwell allegedly used another social media app and tried to arrange a sex meet-up between him, his fiancee and a 14-year-old girl. Both suspects were talking to Lt. Flowers the whole time.

“It was extremely graphic and it was dangerous and this all, this whole case took an hour and a half, that's how fast they move,” Lt. Flowers explained.

Timothy Johnson was not an undercover sting. A 16-year-old El Reno girl came forward saying she met Johnson at church and he later took her to a parking lot off I-40 and Cimarron Road where he forced himself on her.

“He confessed that, yeah, he went too far, he got on top of her and did these horrible things against her will,” Lt. Flowers told News 9.

Flowers said for every suspect caught, others keep preying on victims.

“We still get more and more,” Lt. Flowers said. “It doesn't slow it down one bit and it's sad, it's sad that there is that much of a problem,” he added.

However, with each arrest, Flowers said lives were saved and that is what matters. So, he and the rest of the Internet Crimes Against Children Task Force will keep on working behind the scenes.

“They're looking for a kid and we are glad it's us and not a real child,” Lt. Flowers said.

Both Erwin and Maxwell remain behind bars on a $50,000 bond.

Johnson has bonded out.

Lt. Flowers said parents should watch their children's usage of Instagram, Twitter, Facebook, Kik, Tinder, Snapchat, Meet Me and Tango.

Be concerned if your child cannot explain why they have certain friends on those apps.
