A Connecticut man who told authorities his stepmother held him captive in their home for two decades since he was a boy has asked why his she is not behind bars while awaiting trial, a state prosecutor said Friday. Don Therkildsen Jr., a supervisory assistant state's attorney, made the remark during a court hearing in Waterbury for Kimberly Sullivan, who pleaded not guilty Friday to charges that included kidnapping and felony assault. Sullivan was ordered to be placed on electronic monitoring, and Therkildsen also asked for house arrest over concerns she could flee.
