Joe Kimball was a young reporter on the Minneapolis Star Tribune who happened to be in Duluth when the Congdon murders occurred in 1977. His reporting on the murders placed him in the public's eye throughout the trial. Marjorie and Roger Caldwell were tried separately for the crimes. Roger Caldwell was convicted, but Marjorie was acquitted by a jury. She was later convicted in unrelated arson charges and suspected of murdering her second husband. Mr. Kimball's perennially popular book, Secrets of the Congdon Mansion, takes you through the history of the crimes, and provides maps and floor plans of the mansion. On this 35th anniversary of the murders, Mr. Kimball will outline the events of that night, the personalities involved, and share his views on the outcome of the case. Saturday, October 6, 10:30 a.m.
