This Jacobean-style estate was built in 1905 by Minnesota captain of industry Chester Congdon. And it was the opulent scene of a double murder in 1977. Congon's daughter Elisabeth eventually inherited the place and grew old there, in the company of her adopted daughter, Marjorie Mannering Congdon, and nurse, Velma Pietila. It was Marjorie, eager for her inheritance, who conspired with her second husband, Roger Caldwell, to smother the elder Congdon to death as she slept. When the nurse tried to stop the crime in progress, she was also killed.
Caldwell was convicted for the murders, but his sentence was overturned on appeal. Before he could be retried, he confessed to the killings and committed suicide in 1988. Marjorie Congdon was acquitted on all counts and went on to live a life of crime, including charges for bigamy, arson, the alleged murder of her third husband, and more recently in 2005, theft, computer tampering, and forgery. The house is now open to the public for tours, on which you walk through the landing and bedrooms where the murders took place.
