The murder of seven-year-old Jaclyn Marie Dowaliby occurred on September 10, 1988, when she was abducted from her bedroom in Midlothian, Illinois. Her body was discovered on September 14, 1988, in a wasteland area of Blue Island, showing signs of ligature strangulation.

However, his conviction was overturned in 1991, leading to his release, and the case remains unsolved, classified as one of the most notorious cold cases in the Chicago area, with no new leads or suspects identified.
David Dowaliby is believed by some to have been wrongfully convicted, with speculation suggesting that the true killer may still be at large.

Additionally, there are theories regarding possible involvement by individuals in the local area, given the circumstances surrounding her abduction and the location where her body was found.
The Tragic Unsolved Case of Jaclyn Dowaliby
A Night of Innocence Shattered
On September 10, 1988, a serene neighborhood in Midlothian, Illinois, was rocked by the disappearance of seven-year-old Jaclyn Marie Dowaliby. The child was snatched from the safety of her bedroom under mysterious circumstances, setting off a chain of events that would haunt her community for decades. Her strangled body was discovered four days later, abandoned in the wasteland of Blue Island, Illinois, wrapped in a blanket.
Early Life: A Family's Joy
Born on May 17, 1981, in Chicago, Illinois, Jaclyn was the cherished daughter of James "Jimmy" and Cynthia Guess. The couple's love story began at a skating rink in the 1970s but ended in a bitter custody battle, which Cynthia won shortly after Jaclyn's birth. In 1982, Cynthia married David Dowaliby, who soon adopted Jaclyn, and the young girl believed him to be her biological father. The Dowalibys grew into a loving family, welcoming Jaclyn's half-brother, David Jr., in 1984. Neighbors described them as affectionate and nurturing, relying on gentle discipline for their children.
Jaclyn was a bubbly and popular student at Central Park Elementary School. Her mother worked at Oak Forest Hospital, and her stepfather was a construction foreman. They lived in a peaceful one-story ranch on 148th Street, surrounded by nature reserves. In the summer of 1988, Cynthia discovered she was expecting another child, adding to the family's joy.
The Night of September 9, 1988
The evening of September 9 began like any other. Cynthia treated her children to dinner at a local Kentucky Fried Chicken, while David socialized at a Blue Island bowling alley. He returned home at 9:20 p.m. to find his family safe, and guests soon departed. At 10:30 p.m., Jaclyn, wearing her nightgown, kissed her mother goodnight and settled into bed with a Sears catalog. Her stepfather retired shortly after.
Cynthia's last check on Jaclyn was at 11 p.m., finding her daughter asleep. The parents claimed they slept soundly and heard nothing unusual that night.
The Horrific Discovery
The calm morning of September 10 shattered when David awoke at 8 a.m. and noticed Jaclyn wasn't watching cartoons as usual. Her bedroom was in disarray, with an open suitcase and scattered clothes. Her blanket was missing, and the kitchen door was ajar. Alarmed, David and Cynthia searched for Jaclyn, discovering a cut screen and broken basement window, indicating forced entry. They reported her disappearance to the Midlothian Police Department.
The Investigation Unfolds
The Midlothian Police launched an extensive search for Jaclyn, involving all-terrain vehicles, search dogs, and the U.S. Coast Guard. Flyers were distributed widely, and the community tied yellow ribbons on trees in solidarity. Despite the intensive search, few clues emerged. A forensic examination of the house revealed undisturbed dust on the windowsill, suggesting the break-in was staged. A hair of Negroid origin was found on Jaclyn's pillow, and no recent fibers or hairs were detected at the entry points.
Unraveling Theories
Initial suspicions fell on Jaclyn's biological father, James Guess, but he was quickly ruled out as he was incarcerated in Florida. The absence of a ransom demand led authorities to consider both kidnapping and parental involvement. David Dowaliby willingly took a polygraph test, which he claimed supported his innocence.
The Grim Discovery
On September 14, 1988, Michael Chatman discovered Jaclyn's body near the Islander Apartments in Blue Island, six miles from her home. Her body was wrapped in a blanket, her nightgown still on, but her underwear discarded nearby. Dr. Robert Stein's autopsy revealed she was strangled with twine, and decomposition prevented determining sexual assault. A Caucasian hair was found in her underwear, and a Negroid hair on the twine around her neck. Her fingernails contained type O blood, matching her family's except for David Sr., who was type A.
The Case Against the Dowalibys
As the investigation progressed, focus shifted back to the Dowalibys. An eyewitness, Everett Mann, claimed to have seen a dark Chevrolet Malibu at the crime scene, identifying David as the driver from a lineup. The Dowaliby family car, a light blue Chevrolet Malibu, underwent forensic examination, revealing human hair but no definitive evidence linking it to Jaclyn's transport. Despite their cooperation, David and Cynthia were arrested and charged with Jaclyn's murder based on what authorities called "excellent evidence."
Legal Proceedings and Aftermath
The trial captivated the public, with Cynthia being acquitted and David convicted and sentenced to 45 years. However, his conviction was overturned in 1991, and he was released from prison. The case remains a chilling unsolved mystery, forever etched in the annals of Chicago's cold cases.
