I remember reading about Colleen Stan who was kidnapped and held as a slave for 7 years, put into a coffin under a bed for 23 hours a day.

"According to Stan, Hooker feared he had given his slave too much freedom - he took her back to his mobile home and locked her in the wooden box under his water bed; she remained in the box 23 hours a day for the next three years.[15] Bodily functions were dealt with by her using a bed pan which she hooked under herself with her feet.
It was stated in court that the Hooker children were told "Kay" (a form of Stan's slave name K) had gone home and that at night, after the children had gone to bed, Hooker would take her out of the box to feed and torture her.[16] She was not allowed to make any noise and she had to lie still twenty-three long hours at a time, in the dark with little air to breathe. In the summer conditions were especially harsh on her as the temperatures would swelter to over 100 degrees in her box. She ate scraps which were always cold and usually leftovers."
Says he got kidnapped while hitch hiking. Interesting because all three women in the Cleveland story got kidnapped after accepting a lift too. Not very bright.
