The Carla Walker case is the 1974 abduction and murder of a seventeen-year-old Fort Worth high school student that stayed unsolved for forty-six years, until forensic genetic genealogy identified Glen Samuel McCurley in 2020. He pleaded guilty to capital murder, received a life sentence, and died in prison in 2023.
The Valentine’s Dance and the Bowling Alley Parking Lot
Walker was a junior at Western Hills High School. On the night of February 16, 1974, she went to her school’s Valentine’s Day dance with her boyfriend, Rodney McCoy. Afterward, McCoy drove to the Ridglea Bowl parking lot in Fort Worth. They stopped there briefly.
An armed man walked up to the car, struck McCoy in the head with the butt of a pistol, and dragged Walker out of the vehicle. McCoy lost consciousness. When he came to, she was gone.
Search parties combed Tarrant County for three days. On February 20, her body was found in a culvert near Benbrook Lake. She had been strangled. Investigators at the scene believed her attacker had kept her alive for a period before killing her, and that she had died only hours before she was found.
The Suspect Who Slipped Through in 1974
Detectives recovered biological evidence from Walker’s clothing. They also recovered a magazine clip in the bowling alley parking lot that belonged to a newer-model .22 Ruger handgun. The Bureau of Alcohol, Tobacco, and Firearms pulled purchase records for that model in the Fort Worth area and returned a list of roughly two dozen buyers.
One of the names was Glen McCurley, a thirty-one-year-old truck driver. In early March 1974, two detectives went to his home. McCurley told them his Ruger .22 had been stolen from his pickup six weeks earlier while he was fishing. He agreed to a polygraph and passed. The task force cleared him and, as a lead detective later acknowledged, never thought about him again.
The investigation continued for months. Detectives interviewed hundreds of people and chased tips that led nowhere. Without a way to analyze the microscopic biological material recovered from Walker’s clothing, the case went cold.
How DNA Finally Identified the Killer
The Fort Worth Police Department kept the biological samples in storage. DNA profiling did not exist in criminal investigations until the mid-1980s, and forensic genetic genealogy would not emerge for decades. The samples still had to be viable when the technology caught up. They were.
In 2020, Fort Worth police partnered with Othram Inc., a private forensic laboratory that specializes in pulling usable DNA from degraded or limited samples. Previous attempts to process the evidence had failed. Othram’s technology succeeded, developing a DNA profile from material found on Walker’s bra.
The profile was not in CODIS, the FBI’s law enforcement DNA database. So investigators went a different direction. Forensic genetic genealogy uploads a suspect profile to public genealogical databases where people have voluntarily shared their own DNA to trace family history. Genealogists identify distant relatives of the unknown suspect, build out an extensive family tree, and work through branches until they reach a specific person. The Walker case was one of the early high-profile demonstrations that the technique could crack cases conventional databases never would; by the end of 2022, researchers had documented more than 500 cases solved through the method.
The trail pointed to Glen McCurley, the same man detectives had cleared in 1974.
The Trash Pull and the Arrest
A genealogical lead is not courtroom evidence. Detectives needed McCurley’s own DNA for a direct comparison. Rather than tip him off with a formal request, they conducted surveillance and recovered a discarded item from his household trash that carried enough biological material to test. Courts have generally held that trash placed at the curb for collection carries no expectation of privacy.
The laboratory confirmed the match to the profile from Walker’s bra. Detectives interviewed McCurley at his home, where he made statements that contradicted the physical evidence. Authorities arrested the then-seventy-seven-year-old on a capital murder warrant in September 2020, forty-six years after the crime.
Why McCurley Did Not Face the Death Penalty
Prosecutors charged McCurley under Texas Penal Code Section 19.03, which classifies a murder committed during a kidnapping as capital murder.1State of Texas. Texas Penal Code PENAL 19.03 – Capital Murder Walker had been forcibly taken from her boyfriend’s car and killed during or following that abduction.
Sentencing, though, was constrained by the date of the crime. Walker was murdered in February 1974, during the period when the death penalty was unconstitutional nationwide. The U.S. Supreme Court’s 1972 ruling in Furman v. Georgia had struck down existing death penalty statutes as cruel and unusual punishment.2Justia. Furman v. Georgia, 408 U.S. 238 (1972) Capital punishment did not resume until Gregg v. Georgia in 1976. Because the applicable law is the law in effect when the crime was committed, the death penalty was off the table. Life in prison was the maximum.
The Plea and the Sentence
McCurley’s case went to trial in Tarrant County. After two days of jury proceedings, prosecutors played audio from his interrogation in which he could be heard saying, “I guess I choked her to death.” He then changed course. He waived his right to a jury trial, entered an open plea of guilty to capital murder, and was sentenced to life imprisonment.3Justia. Glen Samuel McCurley v. The State of Texas The shift stunned people in the courtroom, including Walker’s family, who had waited decades for that moment.
McCurley appealed. The Texas Second Court of Appeals affirmed the judgment.3Justia. Glen Samuel McCurley v. The State of Texas He died of natural causes in July 2023 at the Telford state prison in Bowie County, Texas, at age eighty. Investigators publicly raised the question of whether he may have had other victims who remain unidentified.
The Carla Walker Act
The resolution of the case had a direct legislative effect in Texas. Lawmakers introduced the Carla Walker Act to make it easier for law enforcement agencies to submit cold case evidence for advanced forensic testing. The bill reflected a broader recognition that thousands of unsolved violent crimes across the state might be solvable if degraded DNA evidence could be reprocessed with newer technology.
