Lil' Miss murder

At the time of her disappearance, Kimmell's case was profiled nationally on the series Unsolved Mysteries, and her murder has been subject to various true-crime documentary segments. A book, Rivers of Blood, was published in 2009 which details her disappearance and murder.

Eaton's property was awarded to the Kimmell family after a wrongful death lawsuit, and the buildings were burned to the ground on July 18, 2005, on what would have been Lisa Kimmell's 36th birthday.

Both Kimmell's and Bechtel's cases were profiled on Unsolved Mysteries and Nightmare Next Door. Kimmell's mother, Sheila, published a book, The Murder of Lil' Miss, about her daughter's life and murder, in 2005. True crime author Robert Scott wrote a book called Rivers of Blood (2009) that detail Eaton's life and crimes, including the disappearance and murder of Lisa Kimmell. The case was also profiled in an episode of On The Case with Paula Zahn.

Eaton was found guilty of all charges and sentenced to death on March 20, 2004. He appealed this conviction and lost. Scheduled to be put to death in February 2010, he sought and received a stay of execution in December 2009. It was overturned in 2014. The state originally planned to seek a reinstatement Eaton's of death sentence, before dropping their request in September 2021. Prior to his removal from death row, Eaton was the only inmate on Wyoming's death row.

Kimmell remained a missing person for eight days before her body was discovered floating in the North Platte River near Casper, Wyoming. Evidence from a nearby bridge revealed she had been bludgeoned and stabbed to death there, before being thrown into the water. Kimmell's murder remained a cold case for 14 years, until DNA profiling linked Dale Wayne Eaton to her kidnapping, rape, and murder. In 2002, Kimmell's missing car was recovered from Eaton's property, where he had buried it after her abduction and murder. Eaton was convicted of first degree murder and sentenced to death in 2004. His death sentence has since been overturned.

In the summer of 2002, investigators researching cold cases came across Kimmell's rape kit, and a DNA profile was developed from the seminal evidence. The CODIS database matched the DNA to Dale Wayne Eaton, 57, of Moneta, Wyoming, who was then serving time in Englewood federal prison at Littleton, Colorado on an unrelated weapons charge. Eaton's DNA profile was placed in the CODIS database in 1997 after he was arrested on a separate charge: he had stopped to offer assistance to the Breeden family, whose car had broken down, but then he kidnapped the family at gunpoint. After his arrest for this kidnapping, Eaton escaped, but was later recaptured in Shoshone National Forest. At that time he possessed a weapon, elevating his crime to the federal level. He was then incarcerated in federal prison, where he was obliged to submit a DNA sample.

Eaton's next door neighbors reported to investigators that they had seen him digging a large hole on his property in Moneta, Wyoming, approximately 75 miles (121 km) from Casper. The site was excavated in the summer of 2002, and Kimmell's Honda CRX was unearthed, still bearing her distinctive "LIL MISS" license plate. Eaton was subsequently charged with eight crimes connected to the Kimmell case, including first-degree premeditated murder, aggravated kidnapping, aggravated robbery, first-degree sexual assault, and second-degree sexual assault.

Amy Wroe Bechtel, a woman who disappeared in 1997 from Lander, Wyoming, is considered by law enforcement to be among the Great Basin killer's potential victims. Bechtel disappeared while going for a run outside Lander. When her husband returned home at 4:30 p.m., she was not home. Bechtel's white Toyota station wagon was found parked off a dirt road in the Shoshone Forest. No trace of Bechtel has been found but subsequent investigation placed Eaton on business in the area around the time of the disappearance.

On March 25, 1988, Kimmell left from Denver, heading north to her parents' home in Billings. Her mother, Sheila, had departed from Denver on a flight to Billings the day before, as she was scheduled to go on a skiing trip.

Kimmell's case was profiled on the television program Unsolved Mysteries within weeks, and A&E's Cold Case Files in the years since, with each case concentrating on locating witnesses who might have seen her black 1988 Honda CR-X automobile with a Montana plate bearing a personalized "LIL MISS" license plate. Investigators knew recovering the car was extremely important as it would be a direct link to the killer.

Law enforcement has suspected that Kimmell's murder may have been part of a pattern of serial killings, known as the Great Basin Murders, which took place between 1983 and 1996 in Wyoming. Most of the victims were young women who initially disappeared, only to be later found murdered. Because Kimmell's body was located in a popular fishing spot (creating a public spectacle) and that her car was buried on his property (kept as a trophy) it is believed that Eaton exhibited some of the tell-tale signs of being a serial killer.

The Lil' Miss murder is the name given to the murder case of Lisa Marie Kimmell (July 18, 1969 – April 2, 1988), a young woman who disappeared while traveling from Denver, Colorado, to her family's home in Billings, Montana. Her case was given its name due to her vehicle, a Honda CR-X, which had the distinctive personalized license plate reading "LIL MISS", a fact widely publicized in efforts to recover her.

Lisa Marie Kimmell was born July 18, 1969, in Covington, Tennessee, the eldest of three daughters born to Sheila and Ronald Kimmell. She was raised in Billings, Montana. Upon graduating from Billings Senior High School in 1987, Kimmell took a job managing an Arby's restaurant in Aurora, Colorado, near Denver. Kimmell's mother, Sheila, was a regional manager of the restaurant chain, and the two commuted between Billings and Denver—a distance of approximately 555 miles (893 km)—weekly. During the week, Lisa and her mother resided in an apartment complex in Denver, each in her own separate apartment, and would regularly return to Billings, where Ronald and the other Kimmell children resided.

Dale Eaton was born in 1945 and reportedly had a difficult upbringing.
