A Tennessee couple made their first appearance in court Friday to face allegations that they sold their daughters — ages 5, 12, 15 and 17 — to create child pornography.

Connie Sue McCall, 40, and her husband Ronnie Lee McCall, 61, were charged with the unspeakable crimes by a federal grand jury.

Investigators said paperwork shows they were selling their children to take part in sex films and that the young girls were forced to perform sexual acts in a number of different places. The parents were also strung out on bath salts at the time, according to WATE-TV.

The revelations were only discovered when investigators arrested the parents after discovering deplorable living conditions inside their home.

“When the youngest child was taken in, several if not all of her teeth were rotted,” District Attorney Tony Clark said, according to WCYB-TV. “There was animal waste inside the home.”

Debbie Dunn with the Johnson City Police Department added that one of the girls had both head and body lice, flea bits, ring worm and rotten teeth.

“The amount of tooth decay, you can imagine, was extremely painful. She had black teeth, and holes in all the teeth, just really inexcusable,” Dunn said, according to WATE-TV.

After questioning the children, Johnson City Police determined the kids had been sold to create child pornography.

“There was money that changed hands between the individuals that were taking pictures and the parents,” Clark said. “The children said that they had been taken to various locations and performing sex acts with an adult.”

The U.S. Attorney’s Office took charge of the case after learning one of the girls was allegedly taken to South Carolina to film a sex film.

“When you have parents allegedly making money off their kids through pornography and exploitation, even after 20 years, it’s one of the worst cases I’ve ever seen,” 1st Judicial District Attorney General Tony Clark said.

The girls are now in the custody of child protective services.
