A century after the killing of a well-known coal mine watchman in southern Iowa, the murder of Carl Axel Deer remains one of the state’s enduring unsolved cases.
Known to local miners as “The Big Swede,” Deer lived a solitary life near Thistle Mine No. 4 in the coal mining community of Cincinnati, Iowa. Although he used the name Carl Johnson, his true identity was later identified as Carl Axel Deer.
For more than a decade, Deer lived in a tent near the mine and was known for his reliability. Fellow workers became concerned when he failed to report for duty for several days at the end of May 1925.
When coworkers went to check on him, they found his tent in disarray, appearing to have been thoroughly searched. As they prepared to leave, they heard a faint moan and discovered Deer hidden beneath a mattress. He had suffered severe head wounds and other injuries.
Authorities believe Deer was attacked with an axe while inside his tent. He was transported to St. Joseph’s Hospital in Centerville but never regained consciousness. Deer died from his injuries on June 3, 1925.
Investigators suspected robbery as the motive. Deer was known for living frugally, and rumors circulated that he kept a large amount of cash hidden in his tent. Following the attack, no money was found at the scene.
While two men were reportedly arrested shortly after Deer’s death, authorities were unable to build a case against them. No one was ever convicted, and the murder remains unsolved.
Today, the death of Carl Axel Deer stands as one of Iowa’s historic cold cases, continuing to intrigue researchers and local historians nearly 100 years later.
