Shaun Lefleur Sentenced to Life in Prison for Murder

On May 23, 2025, a jury found a man guilty of first-degree murder after a lengthy investigation.

On April 21, 2024, the New Mexico State Police Uniform Bureau in Ruidoso took a report from a male who reported to have information of a homicide that occurred in Otero County, New Mexico. New Mexico State Police Investigations Bureau agents out of Alamogordo, NM were then called out to investigate.

The reporting party led New Mexico State Police uniform and the New Mexico State Police Investigations Bureau to an area of the desert near Oliver Lee State Park just south of Alamogordo where the body of Nancy Lefleur, (67) of Arkansas, was found buried in a shallow grave and wrapped in a tarp. Multiple items of evidence were collected from the scene by NMSP Crime Scene Team including ammunition casings.

The Office of the Medical Investigator exhumed the body of Nancy Lefleur, and an autopsy was performed. During the autopsy, Nancy was found to have died from two gunshot wounds to the head. During the extensive investigation and after multiple interviews, Shaun Lefleur (56), husband to Nancy, was charged with First Degree Murder and Tampering with Evidence. Lefleur was later arrested on April 25, 2024, near Cloudcroft, New Mexico.

Investigators said the couple came to Otero County in late 2023, and not long after, LeFleur was accused of beating his wife.

The couple began staying at a remote campsite outside Oliver Lee Memorial State Park, but LeFleur decided to move their camp to an even more remote area of the desert, according to prosecutors.

He started looking online for where he could buy a gun and places he could flee to in Mexico, investigators said.

Then one night in February 2024, “he forced his wife Nancy out of their tent and onto her knees,” prosecutors said.

Investigators said they learned LeFleur fatally shot her “execution style,” wrapped her body in a tarp and buried her body in a shallow grave.

He fled to Texas, but a month later he came back to the scene in the desert and set up a camp feet away from the grave “to discourage people from stumbling upon the body,” prosecutors said

The presiding judge said LeFleur “showed no remorse for the murder of his wife” and no one “believed his testimony,” according to the district attorney.

On Friday, May 23, 2025, following a 4-day jury trial, Shaun Lefleur was found guilty by an Otero County jury of First-Degree murder and Tampering with Evidence. Following the guilty verdict, Lefleur was sentenced to life in prison.
