ST. CHARLES, Missouri — A 24-year-old Missouri woman was sentenced to eight years in prison on Tuesday for her role in the selling of two high school girls for sex. In court, Tiffany Piper explained how she managed the sex business and bought online ads that invited guys to pay for sex with teens in extended stay motels, according to a report on

The sex crimes occurred in 2012, seven years after Tiffany Piper’s sister 13-year-old Bianca Piper disappeared from Lincoln County, Missouri.

Shortly after Bianca vanished, photos of Tiffany appeared online. Someone was trafficking the missing girl’s older sister for sex.

“That’s what makes it difficult in this case,” St. Charles County prosecutor Tim Lohmar told Fox2Now. “There’s a spectrum in these cases where someone can go from victim to perpetrator and that’s what we have in this case. At some point she was no longer a victim in this case, because she perpetrated the same crimes that were perpetrated upon her.”

The person who initially trafficked Tiffany Piper for sex has not been arrested. Tiffany Piper would not give up that person’s name.

“The way that this business is sorted as it is, it just lends itself to that,” Lohmar said. “Somebody is going to be on the ground, somebody is going to be doing the dirty work and somebody else is going to benefit and profit from that.”

Bianca Piper remains classified as a missing person.
