Dee Warner Murder Case: Timeline of the Investigation and Final Verdict

The disappearance and murder of Michigan businesswoman Dee Warner became one of the state’s most closely followed criminal cases. What began as a missing person investigation in 2021 eventually led to a murder conviction after investigators uncovered critical evidence years later.

The case drew widespread attention because of the long search, the discovery of Warner’s remains on family property, and the emotional fight for justice led by her loved ones.

Dee Warner Disappeared in 2021

Dee Warner vanished from her Michigan farm on April 25, 2021. According to investigators, she was last seen at the property she shared with her husband, Dale Warner.

Family members quickly became concerned after they were unable to contact her. Her vehicles remained at the home, but she was nowhere to be found. Search teams spent months looking for clues while authorities continued investigating her disappearance.

As the years passed without answers, Dee’s family remained determined to uncover the truth, keeping public attention focused on the case.

Investigation Led to Murder Charges

In November 2023, investigators arrested Dale Warner and charged him with murder and evidence tampering, despite Dee’s body not yet being located.

Months later, in August 2024, authorities discovered human remains hidden inside a fertilizer storage tank on the Warner property. The remains were later identified as Dee Warner.

A medical examination concluded that she died from strangulation and blunt force injuries, and investigators alleged that efforts had been made to conceal the crime.

During the trial, prosecutors argued that the couple’s marriage had significantly deteriorated. Evidence presented in court included text messages and testimony suggesting Dee had planned to separate from her husband and make major changes to their shared business interests.

Jury Convicts Dale Warner

Following a lengthy trial in early 2026, a jury found Dale Warner guilty of second-degree murder and evidence tampering.

In May 2026, the court sentenced him to up to 70 years in prison, with consecutive penalties for the evidence tampering conviction. Under the sentence, he will become eligible for parole only after serving several decades.

For Dee Warner’s family, the verdict marked the end of a painful legal battle that lasted nearly five years. Although they said no sentence could replace their loved one, they described the conviction as long-awaited justice.
