Jacquelyn “Jackie” Tendall Found Murdered in Orland Park Illinois

On December 10, 1988, the quiet suburban town of Orland Park, Illinois, was rocked by a brutal and senseless crime that would leave the community in shock and forever alter the lives of those who knew Jacquelyn “Jackie” Tendall. A 28-year-old mother of two, Jackie was found murdered in her home, her life tragically cut short in an act of violence that remains unsolved to this day. This article delves into the details of Jackie’s life, the events surrounding her murder, the investigation that followed, and the lingering questions that continue to haunt her family, friends, and law enforcement.

The Life of Jacquelyn “Jackie” Tendall

Jacquelyn Tendall, known to her friends and family as Jackie, was a vibrant and beloved member of her community. Born on March 12, 1960, Jackie grew up in the Chicago suburbs and was known for her warm personality, infectious smile, and dedication to her family. She married John Tendall, and the couple settled in Orland Park, a peaceful and affluent suburb southwest of Chicago. Together, they had two children: a 4-year-old daughter and a 2-year-old son.

Jackie worked as a dental hygienist and was highly regarded by her colleagues and patients. She was described as a devoted mother who doted on her children, often taking them to parks, playdates, and community events. Friends and family recalled her as a kind, outgoing, and caring individual who always put others first. However, beneath the surface of her seemingly idyllic life, there were tensions and complexities that would later come to light.

The Night of December 10, 1988

The events of December 10, 1988, began like any other day for the Tendall family. John Tendall, Jackie’s husband, left the house that evening to attend a social event, leaving Jackie at home with their two young children. The children were put to bed early, and Jackie spent the evening relaxing in the family’s modest ranch-style home on West 82nd Avenue.

At some point during the night, an intruder entered the Tendall home through an unlocked door. The exact time of the break-in remains unclear, but what is known is that Jackie was attacked in her bedroom. She was brutally beaten and strangled, her life extinguished in a violent and senseless act. Remarkably, her two children slept through the entire ordeal and were unharmed.

When John Tendall returned home later that night, he was met with a scene of unimaginable horror. He found Jackie’s lifeless body in their bedroom and immediately called 911. Paramedics and police arrived shortly after, but it was too late—Jackie was pronounced dead at the scene.

The Crime Scene and Initial Investigation

The crime scene was both chaotic and perplexing. Jackie’s body showed signs of a violent struggle, with evidence of blunt force trauma and strangulation. The bedroom was in disarray, suggesting that Jackie had fought back against her attacker. However, there were no obvious signs of forced entry, leading investigators to believe that the killer may have known Jackie or had been familiar with the layout of the home.

Police quickly began piecing together the events of that night. They interviewed John Tendall, who provided an alibi for the time of the murder. He claimed to have been at a social gathering with friends, and while his alibi was initially corroborated, investigators remained cautious. As is often the case in such investigations, the spouse is considered a prime suspect until proven otherwise.

The couple’s two children, who were too young to provide any meaningful information, were taken into the care of family members. The community, meanwhile, was left reeling from the shock of such a violent crime occurring in their quiet neighborhood.

The Suspects and Theories

As the investigation progressed, several potential suspects and theories emerged. The most prominent of these centered on John Tendall and a man named David Hendricks, who had been having an affair with Jackie.

John Tendall: The Husband

John Tendall was the first person of interest in the case. As Jackie’s husband, he stood to benefit from her life insurance policy, which was worth a significant amount of money. Additionally, investigators learned that the couple’s marriage had been strained in the months leading up to Jackie’s murder. Friends and family reported frequent arguments and tension between the two, though no one could have predicted such a tragic outcome.

Despite these red flags, John had a seemingly solid alibi. He had been at a social event with friends at the time of the murder, and several witnesses confirmed his presence there. However, investigators noted that his behavior in the aftermath of Jackie’s death was somewhat unusual. He appeared detached and emotionless, which raised suspicions among law enforcement.

David Hendricks: The Lover

David Hendricks, a local businessman, became another key figure in the investigation. Hendricks had been having an affair with Jackie for several months, and their relationship was reportedly tumultuous. According to friends, Jackie had been considering ending the affair, which led investigators to speculate that Hendricks may have killed her in a fit of rage or to prevent her from exposing their relationship.

Hendricks was questioned extensively by police, but like John Tendall, he had an alibi for the night of the murder. He claimed to have been at home with his wife and children, and while his alibi was partially corroborated, investigators remained skeptical. Hendricks’s behavior during the investigation also raised eyebrows. He was evasive and uncooperative, refusing to answer certain questions and often changing his story.

Other Theories

In addition to John Tendall and David Hendricks, investigators explored other possibilities. Some speculated that the murder could have been a random act of violence, though this seemed unlikely given the targeted nature of the attack. Others wondered if Jackie had been involved in something that put her in danger, though no evidence of this ever surfaced.

The Investigation Hits a Wall

Despite months of intense investigation, the case began to stall. Physical evidence was scarce, and the lack of a clear motive made it difficult for investigators to build a strong case against any one suspect. The absence of DNA technology at the time further complicated matters, as modern forensic techniques that might have helped solve the case were not yet available.

As the years passed, the case grew colder. Leads dried up, and the file on Jackie Tendall’s murder was eventually moved to the unsolved cases division of the Orland Park Police Department. For Jackie’s family and friends, the lack of closure was devastating. Her children grew up without their mother, and the pain of her loss never fully healed.

The Legacy of Jackie Tendall

Jackie Tendall’s murder remains one of Orland Park’s most haunting unsolved crimes. Her death left a void in the lives of those who knew her, and the unanswered questions surrounding her murder continue to weigh heavily on the community.

Over the years, there have been occasional efforts to revive the investigation. Advances in forensic technology have raised hopes that new evidence could be uncovered, but so far, no breakthroughs have been made. The case has been featured on various true crime shows and podcasts, keeping Jackie’s story alive and generating renewed interest in finding her killer.

For Jackie’s family, the pain of her loss has never faded. Her children, now adults, have had to grapple with the knowledge that their mother’s murderer has never been brought to justice. They continue to hope that one day, the truth will come to light and they will finally have the closure they so desperately need.

Conclusion

The murder of Jacquelyn “Jackie” Tendall is a tragic and deeply unsettling story that serves as a reminder of the fragility of life and the enduring impact of violence. Despite the passage of time, the questions surrounding her death remain unanswered. Who killed Jackie Tendall? Was it someone she knew, or was it a stranger? What motivated such a brutal and senseless act?

Until these questions are answered, Jackie’s memory will remain overshadowed by the mystery of her untimely death. Her story is a testament to the importance of perseverance in the pursuit of justice and the need to never forget the victims of unsolved crimes. For those who knew and loved Jackie, the hope for justice remains alive, even as the years continue to pass.
