Introduction

Nestled amidst the pristine shores of Lake Superior in Duluth, Minnesota, the opulent Glensheen Mansion stands as a testament to the Gilded Age and a haunting reminder of a tragic crime that has forever tainted its history. On June 27, 1977, five members of the Congdon family and their night nurse were brutally murdered within the mansion's hallowed halls, sending shockwaves through the community and leaving behind an enduring enigma that has captivated the public and investigators alike.

The Victims

The victims of the Glensheen Mansion murders were:

• Elisabeth Congdon (83) - Matriarch of the Congdon family and widow of Chester Congdon, the mansion's original owner
• Chester Congdon Jr. (50) - Elisabeth's son and President of the Congdon Construction Company
• Nancy Congdon (40) - Chester Jr.'s wife
• Margaret Anderson (60) - Night nurse to Elisabeth Congdon
• Ruth Congdon (56) - Elisabeth's daughter-in-law and Chester Jr.'s brother's wife

The Crime Scene

The murders took place in the early hours of June 27, 1977. The perpetrator(s) entered the mansion through an unlocked door and proceeded to bludgeon each victim to death with a hammer or baseball bat. The crime scene was described as gruesome, with blood and broken glass strewn throughout the house.

Financial Motives and Suspects

Investigators initially suspected financial motives for the murders, as the Congdon family was known for their wealth. Gene Schaffner, a disgruntled former employee of the Congdon Construction Company, was considered a prime suspect but was ultimately cleared. Other suspects included David Hanna Jr., a man with a history of mental illness who was obsessed with Elisabeth Congdon, and Roger Caldwell, a handyman who had previously worked at the mansion. However, no conclusive evidence was ever found to link any of these individuals to the crime.

Common Mistakes to Avoid

There are several common mistakes that can be made when investigating a crime like the murders at Glensheen Mansion:

• Assuming guilt too quickly: Investigators must carefully consider all evidence and avoid jumping to conclusions based on limited or circumstantial information.
• Overlooking potential suspects: Law enforcement should thoroughly investigate all individuals with possible connections to the victims, even those who may seem unlikely at first glance.
• Ignoring new evidence: As new technologies and investigative techniques emerge, it is crucial to revisit unsolved cases and re-examine existing evidence to uncover potential breakthroughs.
