A Late Night Silence in Franklin Township
The sprawling farmland of Lenawee County, Michigan, is defined by its predictable rhythms and tight-knit agricultural community. In late April 2021, that predictability shattered when Dee Ann Warner, a 52-year-old mother and successful business owner, vanished from her home on Munger Road in Franklin Township. She was last seen during the late evening hours of April 24 and the early morning of April 25. According to investigators, her disappearance was immediate and absolute; her vehicles remained in the driveway, her personal belongings were left behind, and her cell phone activity ceased entirely.
In the days following the report of her disappearance, family members and neighbors grew increasingly concerned as Dee failed to contact her adult children or show up for her business obligations. She was the heart of several family-run trucking and farming enterprises, known for her sharp mind and dedication to her work. The initial search efforts involved local law enforcement and hundreds of volunteers scouring the rural fields and woodlots surrounding her property. Despite the massive scale of these searches and the use of specialized K9 units and ground-penetrating radar, no trace of Dee was found for over three years.
As the investigation deepened, the focus shifted toward the dynamics of the Warner household and the business interests Dee shared with her husband, Dale John Warner. Court records show that the couple had been experiencing significant marital and financial strain leading up to April 2021. Witnesses later described a heated argument taking place on the night she vanished. While Dale Warner initially maintained that Dee had simply walked away from her life, investigators found no evidence to support a voluntary departure. The case eventually transitioned from a missing person search to a homicide investigation, even in the absence of a body.
The Pillar of Munger Road
Dee Ann Warner was more than a name on a missing person poster; she was a foundational figure in the Franklin Township community. At 52, she managed the complex logistics of her trucking company with a reputation for toughness and fairness. Those close to her described a woman deeply devoted to her children and grandchildren, emphasizing that she would never have willingly abandoned her family, especially without her phone or access to her finances.
Her disappearance left a void in both her family and the local economy. For three years, her children acted as tireless advocates, organized vigils, and pushed for legal changes regarding how missing person cases are handled in Michigan. They maintained a public presence to ensure her face remained in the community's consciousness, even as the search grew quiet and the legal proceedings against her husband began to take shape in the absence of physical remains.
The Tank on the Property
The investigation took a harrowing and definitive turn on August 16, 2024. During a meticulously planned search of a property owned by Dale Warner, law enforcement discovered human remains. The discovery was not made in the open fields or the nearby woods that had been searched many times before. Instead, the remains were found concealed inside a large, sealed anhydrous ammonia tank—a piece of agricultural equipment common in farming communities but rarely used for storage in the manner discovered.
Forensic experts utilized specialized cutting equipment to access the interior of the tank, which had been welded shut and moved to a specific location on the property. The recovery process was slow and deliberate, requiring a high degree of technical skill to preserve the integrity of the evidence. Shortly after the recovery, DNA testing and dental records confirmed that the remains were indeed those of Dee Ann Warner. The medical examiner subsequently ruled her death a homicide, providing the physical evidence that had been missing since the spring of 2021.
Official Investigative Findings
The Michigan State Police and the Lenawee County Sheriff's Office have maintained a rigorous timeline of the official actions taken in this case. Following Dee’s disappearance in April 2021, authorities conducted dozens of searches across multiple counties and states. In November 2023, even before the body was found, the Lenawee County Prosecutor’s Office felt they had sufficient circumstantial evidence to move forward. Dale John Warner was arrested and charged with open murder and tampering with evidence.
According to investigators, the discovery of the remains in August 2024 significantly strengthened the prosecution's case. Analysis of the anhydrous ammonia tank revealed that it had been modified and sealed shortly after Dee went missing. Court records indicate that the location of the tank and the effort required to conceal remains within it suggest a high degree of premeditation and familiarity with industrial equipment. Following the identification of the remains, additional forensic evidence was gathered from the site to build a comprehensive picture of the events that occurred on the Munger Road property.
