She was 18 and traveling from Denver toward Billings, with a planned stop in Cody. When she did not arrive, her mother reported her missing.
Her body was found in the North Platte River. Her car remained missing for years.
The investigation eventually connected preserved biological evidence to Dale Wayne Eaton. A search of property where he had lived then uncovered the car buried in the ground.
A time and place on the road
The traffic stop fixed Kimmell’s location at approximately 9:08 p.m. It did not establish what happened after she drove away.
A fisherman found her body on April 2 near Government Bridge, southwest of Casper.
The Wyoming Supreme Court’s opinion [1] explains that the cold river complicated estimates of when she died. An exact chronology of captivity cannot simply be inferred from the date she disappeared and the date she was found.
Investigators collected and preserved biological evidence. For a long period, it did not identify a suspect.
That preservation mattered when a later comparison became possible.
The DNA connection
The court dates the breakthrough to 2002, when DNA evidence linked Eaton, who was incarcerated in Colorado on another felony conviction, to the case.
Investigators searched his former property near Moneta. They found parts of Kimmell’s automobile and the rest of the vehicle buried there.
The two developments supported each other. The DNA connected Eaton to biological evidence. The vehicle connected property associated with him to an object that had disappeared with Kimmell.
Different accounts of how the encounter began were presented during the proceedings. One came through another inmate; another through a physician who evaluated Eaton. They were accounts offered in litigation, not an independently observed scene.
A vehicle recovered after fourteen years
The DNA breakthrough did more than provide a name for an old file. Investigators went to Eaton's property near Moneta and recovered Lisa's car, which had been buried there. The car offered a physical connection between the missing traveler and the place linked to the new suspect. It was a different kind of evidence from the biological sample: large, identifiable property that had remained out of view through years of searching. [1]
The discoveries could be checked against one another. A preserved biological sample led investigators toward Eaton; the search then located property connected to Lisa. Neither discovery supplied a complete, minute-by-minute account of her movements after the Douglas traffic stop. The court also acknowledged uncertainty in estimating the time of death because her body had been in cold river water. The map therefore does not draw a continuous journey through the intervening days or assign an invented time to the killing. [1]
A note with a contested author
A separate strand concerned a note left on Lisa's headstone. A handwriting examiner considered Eaton its likely author; Eaton denied writing it. The trial record and later proceedings addressed both the attribution and defense counsel's decision not to contest it in the way Eaton later argued they should have. The lawyers also considered how the note might be interpreted during the penalty phase. [1]
That evidence requires a narrower caption than “the killer's confession.” The handwriting opinion was an attribution, the defendant disputed authorship, and the timing of the note was uncertain. The gallery uses a generic document symbol and reproduces neither handwriting nor an invented message. It places the note beside the DNA and buried vehicle so the reader can see that the evidence differed in strength and meaning. [1]
The original trial also had separate stages: the jury first considered guilt, then punishment. The 2008 opinion reviewed issues arising from both. Later removal of the death sentence changed the punishment without erasing the murder conviction. Keeping those stages distinct helps explain how the case could lead to a new sentencing outcome decades after the decisive physical evidence was found. [1][2]
Trial and the original sentence
A jury convicted Eaton in 2004 of first-degree murder and related crimes, including kidnapping, robbery and sexual assault.
The judgment imposed a death sentence. In 2008, the Wyoming Supreme Court affirmed the convictions and sentence.
That historical opinion is an important source for the evidence. It is not the last word on the punishment Eaton received.
A sentence overturned without an acquittal
A federal court vacated Eaton’s death sentence in 2014 over inadequate representation during the penalty phase.
The murder conviction was not erased by that ruling.
Further proceedings considered whether the state would again pursue capital punishment. Sheridan Media reported [2] that Eaton was resentenced on March 25, 2022, to life imprisonment without parole, with an additional consecutive kidnapping term.
A change from death to life is a major legal outcome. It should appear prominently rather than being buried beneath the original sentence.
The years of sentencing litigation also extended the period in which Kimmell’s family had to return to court and revisit the crime.
What made the breakthrough possible
The case is often remembered through the buried car. Its recovery was striking, but the investigation reached the property because evidence from the original case had survived.
The traffic stop, the river discovery, preserved biological material and the later vehicle recovery performed different evidentiary roles. Together, they supported a prosecution after many years without an identified perpetrator.
Kimmell’s trip had a destination and people expecting her. The missing-person report began when those ordinary plans failed.
The later conviction answered who was criminally responsible. The changed sentence explains where the documented legal process eventually led. Telling only the breakthrough would leave out a substantial part of the case’s history.
