Couple accused of turning a teen into their sex slave and sealing her off from the world for more than five years

A Florida couple is accused of turning a teen into their sex slave and sealing her off from the outside world for more than five years, police said after arresting the two.

Rob Johnson, 44, and his wife, Marie Johnson, 43, of Port St Lucie, were arrested on Tuesday and charged with felony sexual assault charges.

The Port St. Lucie Police Department said the girl was sent to live with the Johnsons when she was 13 years old after her mother died, and soon after her arrival was told she could only be part of their family by having sex with them.

She was told to call Rob ‘master’, investigators said in an arrest affidavit, and Marie Johnson pushed her against a wall and held her by her throat until the girl agreed to the sexual demands.

The girl, who is not identified in police filings, was beaten when she didn’t follow the couple’s directions or complete her chores, according to police.

The girl, who now lives in in Indiana, said the abuse went on repeatedly for more than five years.

All the while, Rob Johnson held Sunday school classes for his family at their home, invoking Old Testament passages to justify the actions, the arrest affidavit said.

Rob Johnson, who was the girl’s mother’s cousin, also gave the girl a ring to show she belonged to him, CBS 12 reported.

Police said the girl, now 21, was homeschooled, not allowed to use the phone and forced to rehearse what to say to doctors if she was asked about sexual activity.

The couple allegedly had sexual relations with the girl twice a week until she was 18 years old, according to WPBF.

The girl eventually was able to leave the home, after her grandmother purchased a plane ticket to bring her to Ohio, the police said.

‘We just want to say how brave our victim is to not only begin this process but to stay with the process,’ Port St Lucie Det Sgt Daniel Harrington told CBS 12.

The Johnsons were freed on bail later on Tuesday, the St. Lucie County Sheriff’s Office said, after each posted $60,000 bond. No attorney was listed for them. A call to their home Wednesday went unanswered.
