( CNN ) -- A Missouri man was sentenced on Wednesday to 20 years in federal prison for his role in the years-long sexual torture of a `` mentally deficient '' young woman that included electrical shock and mutilation , the U.S. Attorney 's Office for the Western District of Missouri told CNN . A federal judge accepted a plea agreement from Edward Bagley Sr. , 46 , in a Kansas City courtroom on Wednesday morning , the U.S. Attorney 's Office said . In January , he pleaded guilty to one of the 11 counts he faced for having a sexual relationship with a minor , who was identified only by the initials `` FV '' ( or Female Victim ) in official documents . Bagley faced life imprisonment . Bagley held the victim as a sex slave from December 2002 to February 27 , 2009 , in his Lebanon , Missouri , trailer home . The woman -- who was a runaway minor at the time when the abuse began -- was sometimes `` hung upside down , '' `` water boarded '' and had animals she cared for shot in front of her by Bagley to coerce her to engage in commercial sex acts , the indictment read . `` In or about December 2002 , ( Bagley ) invited FV , a 16-year-old minor , who grew up in foster care homes , into his residence after she ran away from home and promised her ' a great life , ' including , but not limited to , making her a model and a dancer , and 'making her dreams come true , ' '' the indictment read . `` ( Bagley ) advertised and publicized FV over the Internet and in live web cam sessions as his slave who would engage in sexual acts and could be tortured during live online sessions , or in person , '' an indictment read . Once the victim turned 18 , Bagley had `` FV sign a 'sex slavery ' contract '' and told her the contract `` legally bound her to him as his 'sex slave ' with a term that 'never ' ended , '' according to the indictment . During the six years of abuse , Bagley also performed abortions on the victim using things like `` vacuums , and clothing hangers for the purpose of terminating the pregnancies , '' the indictment said . The victim was discovered by first responders after she suffered cardiac arrest during a torture session on February 27 , 2009 , the indictment read . Five other defendants , including four men and Bagley 's wife , Marilyn Bagley , are scheduled to be sentenced this week . The four men were alleged to have traded Bagley things like `` cigarettes , computer hard drives , sadomasochism videos , coats and meats '' to use the young woman as a sex slave , according to the indictment . The U.S. Attorney 's Office said that lawyers for the victim were seeking $ 738,250 for physical and psychological trauma to their client .
