A man and woman who authorities say prostituted a 14-year-old girl were sentenced to prison Wednesday.

U.S. District Court Judge John D. Bates sentenced Robert Braithwaite, 37, of the District to 10 years on federal charges of sex trafficking of children and other offenses, according to the U.S. attorney’s office.

Tavia Crudup, 23, of Suitland was sentenced to a year and a day for evidence-tampering and other offenses.

They pleaded guilty in September, authorities said.

Braithwate encountered the girl, a runaway from another state, in May, authorities said, and transported her around the area to prostitute her.

Crudup, a prostitute herself, instructed the girl on matters including how much to charge and how to act, authorities said, and helped with transportation.

The girl was picked up for truancy May 31, authorities said, and an investigation led to Braithwaite and Crudup.
