February 27, 1978: Roger Caldwell enters a plea of “not guilty” for the killings at Glensheen 

On this day in Duluth in 1978, Roger Caldwell entered a plea of “not guilty” for the charges of killing Elisabeth Congdon and Velma Pietila at Glensheen, the historic Congdon estate, in June, 1977. Caldwell, a native of LaTrobe, Pennsylvania, was the second husband of Marjorie Congdon, the eldest adopted daughter of Elisabeth Congdon. Caldwell had been arrested in a hospital room, where he landed after he had likely been poisoned by Marjorie (she had attempted to poison her mother a few years earlier). Earlier police had found Marjorie in a Bloomington hotel room with a plastic pantyhose container filled with jewelry that had been stolen from Glensheen the night of the murder. Caldwell was tried, found guilty, and sent to prison. While he was incarcerated, Marjorie stood trial and was found not guilty. Local authorities then made an odd deal with Caldwell: tell us the whole truth and you get off with time served. Caldwell then confessed to the crimes but insisted Marjorie was innocent. He walked free and returned to LaTrobe. Marjorie never rewarded his loyalty. She likely murdered her friend Helen Hagen, then married Hagen’s widower and became a serial arsonist. Caldwell committed suicide in 1988. In his suicide note he claimed he never killed anyone. Learn more about the 1977 crimes at Glensheen and the trials that followed here.
