American History

The events surrounding Lt. Peterson's murder trial was the basis for the book and movie "Anatomy of a Murder".

"Anatomy of a Murder is a 1959 American courtroom drama crime film produced and directed by Otto Preminger. The screenplay by Wendell Mayes was based on the novel of the same name written by Michigan Supreme Court Justice John D. Voelker under the pen name Robert Traver. Voelker based the novel on a 1952 murder case in which he was the defense attorney.[1]"

The couple left Upper Michigan after the trial and divorced but then disappeared. I have read some articles saying that Lt. Peterson may have died in a plane crash in Alaska some years after the trial but I haven't found any info verifying that. As for Charlotte, there is nothing.
