WICHITA, Kan. (AP) — The state of Kansas has sued the family of a deceased Kansas Bureau of Investigation agent who worked on the 1959 murders that became the subject of Truman Capote's novel "In Cold Blood." The lawsuit seeks a decision on the legal ownership of Harold Nye's case files on the murders of the Clutter family in Holcomb. The items appeared on an online auction site earlier this year. Attorney General Derek Schmidt wants a judge to order their return and prohibit their sale, publication or distribution. A Shawnee County judge temporarily blocked their sale last week. In a statement Monday, Schmidt said the files belong to the KBI and should not be auctioned for personal gain. Ronald Nye says the dispute involves personal journals and copies of documents that he feels belonged to his father.
