EL RENO, Okla. - Undercover agents in Canadian County arrested a trucker they said was planning to meet up with a teen girl for sex.
It is quite the problem and one agents said is proven with this case.
In this instance alone, investigators say more than 500 adult men are currently trying to meet up with this particular decoy.
"It is an epidemic," Canadian County Detective Adam Flowers said.
Somewhere along the way one man's sense of right and wrong was blurred, distorted enough that he thought it would be perfectly OK if he tried to have sex with a 15-year-old girl.
"He was driving through Oklahoma and picked up on my decoy ad on the internet and requested to meet," Flowers said. "After I told him I was 15 he, he was still fine with that. He told me he was 38 and then the conversation got very sexual in nature."
The trucker, 38-year-old John Opperman, knew he would be travelling through Oklahoma to Elk City to make a delivery and thought he would plan ahead and make a quick stop for another delivery before he got there.
He told the decoy to meet in the Walmart parking lot in Yukon.
"So from 2:30 in the afternoon to 9 p.m., he was in contact with what he thought was a 15-year-old female," Flowers said.
What he planned to do with the girl is absolutely despicable.
Much of the conversation is too graphic to share but in one text message he asked they decoy if she "ever had a sensual massage" and if she had her "body kissed from top to bottom.
Opperman also sent the "teen" a picture of himself.
When he showed up to meet the decoy he was wearing the same clothes he wore in the picture.
Authorities said Opperman was hoping to meet up with the "girl" each time he traveled through Oklahoma.
"Eventually this would be a once-in-a-while type thing when he would drive through," Flowers said.
Opperman was arrested in the Walmart parking lot and charged with attempting sexual conduct with a minor by use of technology.
