Although acquitted at trial, Borden remains the prime suspect in her father's and stepmother's murders. Writer Victoria Lincoln proposed in 1967 that Borden might have committed the murders while in a fugue state. Another prominent suggestion was that she was physically and sexually abused by her father, which drove her to kill him. There is little evidence to support this, but incest is not a topic that would have been discussed at the time, and the methods for collecting physical evidence would have been quite different in 1892. This belief was intimated in local papers at the time of the murders, and was revisited by scholar Marcia Carlisle in a 1992 essay.
