On November 18, 1987, in the small town of Ina, Illinois, a horrific crime unfolded that would leave a lasting scar on the community. Among the victims was a newborn white female named Casey Elaine Dardeen, who was born during the course of a brutal attack on her family and died within moments of her birth. Her mother, 30-year-old white female Ruby Elaine Dardeen, was seven to eight months pregnant when she was bludgeoned to death with a baseball bat inside the family's mobile home. The trauma from the beating caused her to go into labor, and the newborn, Casey, was then also beaten to death by the assailant or assailants. Casey's three-year-old brother, Peter Sean Dardeen, a white male, was similarly murdered, suffering fatal head injuries. All three were found tucked into bed together, a chilling detail that underscored the calculated cruelty of the crime.
The father, 29-year-old white male Russell Keith Dardeen, was initially considered a suspect when he failed to show up for work and was not found at the scene. However, the following day, his body was discovered in a field about a mile from the home. He had been shot three times and mutilated. His car was later found parked outside a police station in Benton, Illinois, with blood inside. The crime scene at the family's home showed no signs of forced entry, and valuables such as cash and electronics were left untouched, suggesting that robbery was not a motive. There was also no evidence of sexual assault or other typical motives such as drug involvement or infidelity.
Despite extensive investigation, no arrests were made in connection with the quadruple homicide. Years later, convicted serial killer Tommy Lynn Sells claimed responsibility for the murders, alleging he had met Keith at a truck stop and was invited to the home. However, his account was inconsistent and lacked corroborating evidence. Authorities and the Dardeen family expressed skepticism, noting Sells' history of false confessions. He was never charged in connection with the Dardeen murders, and the case remains officially unsolved.
The murders of the Dardeen family, including infant Casey, remain one of the most disturbing and baffling unsolved cases in Illinois history. The brutality of the crime, the lack of a clear motive, and the absence of solid leads have left investigators and the community haunted for decades.
