Canadian County Sheriff's announced Thursday that they arrested 32-year-old Amy Maschell Thompson Wednesday. Investigators accuse her of sexually molesting and raping a 15-year-old boy."This lady is more of a monster," said Undersheriff Chris West. "She preyed on a young boy."Sheriff's deputies said the teen's mother got suspicious after reading his Facebook messages when he forgot to log off her cell phone. Officials said they confronted Thompson and she admitted to groping the teen's bottom and genitals at least six times since February 2014. According to investigators, she quit her job at the center in July but the crimes continued.Authorities told FOX25 the two met while she was working at the Fort Reno Adolescent and Drug Rehabilitation Center in El Reno. Investigators said Thompson planned a 'romantic' meeting with the victim at a motel. We're told the victim snuck out of his home and was taken to the motel by Thompson. Once inside, she admitted to giving the teen alcohol and then raping him."This is the first case of a female child predator we have encountered. Most female's are associated as having maternal instincts and taking care of children, not raping them," said Randall Edwards, Canadian County Sheriff."That's a total betray of trust," said West. "For her to be working at a public facility like that. Also for the young people that are there for treatment."Sheriff's deputies said the center is fully cooperating with authorities. The facility's director, Bill Alexander, released this statement to FOX25 in the wake of the accusations:"On August 13 we were notified by a parent, of a possible inappropriate relationship between an ex-employee and a client who is underage. We worked with the mother to determine if the person accused was actually an employee or ex-employee and notified the Canadian County Sheriff's Office. Our facility is assisting the Sheriff's Office in every way possible to determine times and dates needed as well as possible technological evidence.While we cannot speak to any certain case, and while every person is innocent until proven guilty, we can tell you that our facility takes extensive efforts in screening applicants and making every effort to ensure the safetyof ourr clients. Unfortunately, there is no way to see the future, but we will continue to re-assess our procedures. We believe that anyone who abuses any child should be prosecuted to the full extent of the law and we remain committed to serving the public and continuing to help families and children live more healthy lives."Lt. Adam Flowers heads the Internet Crimes Against Children Unit. He urges parents to become more knowledgeable about their children's cell phone and social media activity."They don't have to be an expert but they need to understand that these are computers," said Flowers. "As they go on everyday they're adding more victims and that's what we need to put a stop to.She was booked into the Canadian County Jail on six counts of lewd acts with a minor and first degree rape. She's being held on a $350,000 bond.
