Anthony Brinkman, 32, allegedly placed an ad online looking for someone to beat and rape his 11-year-old relative while he watched, the St. Louis Post-Dispatch reported.
What Brinkman didn't count on was an undercover officer responding to the request. Officer Randy Vaughn, a spokesman for the St. Louis County Police Department, said the undercover officer agreed to meet the suspect at a predetermined location, KMOV reported.
Brinkman then took his 11-year-old relative 80 miles away from their home in Cuba, Mo. to St. Louis. He thought he was meeting a woman interested in sexually assaulting the girl with sex toys, according to KSDK. When he pulled into the meeting spot -- a Cracker Barrel -- he was immediately taken into custody.
According to the Examiner, Brinkman admitted to police that he placed the ad and that he could "perhaps" be in possession of child pornography.
KMOV-TV reports that county prosecutors plan to ask a grand jury to indict Brickman on additional charges of sex trafficking with a minor. Online court records don't list an attorney on his behalf.
