San Angelo, Texas — 2005–2017
For years, Naomi Michelle Miller was simply gone.
She disappeared in Texas in 2005, but the circumstances surrounding her disappearance remained unclear for more than a decade.
There was no confirmed contact from Naomi. No activity appeared in her personal or banking records. And yet, for years, she was not even officially reported missing.
It would take twelve years before investigators finally discovered where Naomi had been.
Her remains were found buried beneath the grounds of the old San Angelo speedway.
By then, the question was no longer whether Naomi had disappeared voluntarily.
It was what had happened to her.
THE NIGHT NAOMI DISAPPEARED
Naomi Miller disappeared sometime in 2005.
According to relatives, she had been involved in a family argument one night.
After the confrontation, they said, Naomi simply “took off.”
That explanation became part of the story surrounding her disappearance for years.
But there was a troubling detail.
There was no evidence that Naomi had continued living a normal life somewhere else.
According to Tom Green County Sheriff David Jones, investigators found no activity in her personal or banking records after she disappeared.
Still, Naomi’s disappearance was not reported to authorities until December 2015—approximately ten years after she was last known to be present.
TEN YEARS WITH NO ANSWERS
By the time Naomi was officially reported missing, a decade had already passed.
Those years made the investigation more difficult, but authorities continued looking into what might have happened to her.
The case eventually focused on people connected to Naomi.
Her ex-husband, Robert Miller, became the first suspect in the investigation into her death.
Another person also came under suspicion: LuDonna Gail Yoder, who was identified as Robert Miller’s girlfriend.
According to the source, Yoder eventually told investigators that she had disposed of Naomi’s body on the night Naomi was killed.
She said the body had been placed in a shallow grave at Naomi’s former residence in Tom Green County.
THE SEARCH FOR NAOMI
Investigators continued pursuing the case, eventually leading them to the old San Angelo speedway.
On March 8, 2017, twelve years after Naomi disappeared, her remains were discovered buried beneath the former speedway grounds.
The discovery finally gave Naomi’s family an answer to the question that had remained unresolved for so long.
Naomi had not simply walked away.
She had been killed.
THE PEOPLE WHO FACED CHARGES
Robert Miller faced charges in connection with Naomi’s death.
LuDonna Gail Yoder was also arrested in the case.
The source identifies Yoder as Robert Miller’s girlfriend and later states that both Robert Miller and LuDonna Miller—also identified as LuDonna Gail Yoder—pleaded guilty.
Both were sentenced to 38 years in prison.
The case that had begun with a woman who seemingly vanished after a family dispute had ultimately become a murder investigation and a criminal prosecution.
A DISAPPEARANCE THAT LASTED FOR YEARS
Naomi Miller disappeared in 2005.
For years, there were no confirmed records of her movements, no financial activity and no clear explanation of where she had gone.
Her disappearance was not formally reported until 2015.
Then, in 2017, investigators finally located her remains beneath the old San Angelo speedway.
What began as a disappearance eventually revealed a much darker reality.
Naomi had been missing for more than a decade, but the search for answers did not end until investigators finally found where she had been buried.
