Overview

Brown was visiting relatives in El Paso, Texas, during the summer of that year when she disappeared. According to accounts compiled from cold case records and eyewitness recollections, she was last reliably seen on the night of August 9, 1977, socializing with friends near a McDonald’s on Dyer Street before accepting a ride from a man driving a van shortly afterward. The driver claimed he let her out somewhere along the way, and he was considered the last person to report seeing her alive.

Several days later, on August 15, 1977, Brown’s remains were discovered in a remote desert arroyo off O’Hara Road near Anthony, New Mexico, just across the Texas–New Mexico state line. Her body was found badly decomposed, with her feet bound with rope, and other indications suggested possible foul play, though decomposition made a precise cause of death difficult to determine.

Detailed Case Breakdown

The Unsolved Murder of Jimmie Retha Brown

The case of Jimmie Retha Brown remains one of the haunting unresolved murders in the American Southwest. Brown was a 16-year-old teenager whose life was tragically cut short under mysterious and violent circumstances in the late summer of 1977.

Brown was visiting relatives in El Paso, Texas, during the summer of that year when she disappeared. According to accounts compiled from cold case records and eyewitness recollections, she was last reliably seen on the night of August 9, 1977, socializing with friends near a McDonald’s on Dyer Street before accepting a ride from a man driving a van shortly afterward. The driver claimed he let her out somewhere along the way, and he was considered the last person to report seeing her alive.

Several days later, on August 15, 1977, Brown’s remains were discovered in a remote desert arroyo off O’Hara Road near Anthony, New Mexico, just across the Texas–New Mexico state line. Her body was found badly decomposed, with her feet bound with rope, and other indications suggested possible foul play, though decomposition made a precise cause of death difficult to determine.

Investigators identified Brown through dental records and quickly classified her death as a homicide, but no suspect was ever arrested. The case attracted early attention, including searches and interviews, but no charges were ever filed. Suspicions circulated about possible criminal elements involved, including rumored ties to local motorcycle gang activity — speculation that was never substantiated with hard evidence and remains one of several unproven theories about motive and culpability.

A dramatic but ultimately unhelpful twist occurred weeks after Brown’s body was found: a young man named Ricardo Gonzalez, believed to be acquainted with Brown’s social circle, told people he knew who killed her and later died by suicide following a police chase. Authorities examined his claimed lead but concluded it did not yield actionable evidence.

Brown was survived by her family — including parents, siblings, and extended relatives — who were left without closure as the investigation gradually cooled over the decades. She was buried at Fort Bliss National Cemetery after funeral services in El Paso.

Today, her murder is classified as a cold case, and law enforcement occasionally appeals for new information from the public. Despite renewed interest on social media and in true crime communities, no new forensic breakthroughs or suspects have been publicly reported as of the most recent reviews of available documentation.

Investigation Status (as of 2026)

Law enforcement agencies in Doña Ana County, New Mexico and El Paso, Texas still list the case as an unresolved cold case and will accept tips or evidence if new information comes forward.
No arrests or formal charges related to Brown’s killing have ever been made.

The original investigation concluded homicide, but no motive or perpetrator has been identified.

Some speculation about possible gang involvement has circulated, though no evidence has definitively supported that theory.

The case remains open but largely inactive due to the passing of time and lack of leads.

Law Enforcement believe that she was killed elsewhere, possibly in Texas, and then dumped in New Mexico. Jimmie was last seen by a man who offered to provide a place for her to stay when she became belligerent and demanded to be let out of his car. That was the last known time she was alive.
