The man who had left his DNA on Carla Walker’s body in 1974 had been questioned within weeks of her murder. He had sat for a polygraph and passed it. His name was already in the case file. It took forty-six years and a private genetics laboratory to force that name back into the open, and when investigators finally pulled his records, they found something that turned the entire investigation inside out.

Glen Samuel McCurley had told detectives in 1974 that the . 22 Ruger traced to the crime scene had been stolen from his pickup truck six weeks earlier. He said he never reported the theft because he was an ex-convict and did not want the trouble. He passed the polygraph, and the detectives crossed him off the list.

When they searched his home in 2020, they found the gun. It had been in his house the whole time. It was never stolen. Carla Jean Walker was born on January 31st, 1957, in Fort Worth.

She was a junior at Western Hills High School, a cheerleader, and a member of the tennis team. She stood four feet eleven inches tall, and her family called her fiery and stubborn, a spitfire in a small frame. Her boyfriend was Rodney McCoy, an eighteen-year-old senior who was the captain and starting quarterback of the Western Hills football team. On the evening of February 17th, 1974, a Sunday, the school held its Valentine’s dance, and the two of them went together.

They spent the night with friends, and when it ended, they left in Rodney’s car and drove west toward home, toward a parking lot they had stopped in a hundred times before. They drove along Camp Bowie Boulevard, the main commercial strip through the west side of Fort Worth, and pulled into the parking lot of the Brunswick Ridglea Bowl. It was a familiar stop, close to Carla’s neighborhood, the kind of place where teenagers parked after dances and football games. They sat in the car together and talked.

The passenger door was ripped open without warning. A man reached in and began hitting Rodney with the butt of a pistol, fast and heavy, across the head. Rodney tried to fight back, but the blows kept landing, and one after another they drove him down toward unconsciousness. The last thing he saw before the dark closed in was Carla being pulled out of the car by a white man, roughly five feet ten inches tall.

Her voice was the last thing to go, calling out for her dad as the man hauled her into the night. When Rodney came to, the car was still running and Carla was gone. Blood was running down his face from where the pistol had split his scalp. He drove straight to the Walker house and told Carla’s parents what had happened.

Fort Worth police responded and began searching the area around the bowling alley. They canvassed the parking lot, the surrounding streets, and the commercial strip along Camp Bowie. In the lot, they found Carla’s purse. They also found something else on the pavement, small and metal and easy to miss: a detachable magazine from a .

22 caliber pistol. The attacker had dropped it during the struggle. It was the only physical trace he left at the scene. Officers searched through the night and into the morning.

They stopped drivers, checked gas stations, and put alerts out across Tarrant County. Search teams walked vacant lots, drainage ditches, and underpasses. A seventeen-year-old girl had been taken from a parking lot in the middle of Fort Worth on a Sunday night, and there was no trail to follow. There was a purse, and there was a pistol magazine, and there was nothing else.

For three days, Carla’s family waited by the phone. Layton and Doris Walker stayed home in case she called, or in case someone called about her. Rodney McCoy, still bleeding under his bandages, went back to the police station again and again, trying to remember any detail he had missed. On February 20th, 1974, Carla’s body was found in a culvert near Benbrook Lake, roughly thirty minutes south of the bowling alley.

She was on her back. Her dress was torn and bloody. The scene told investigators she had not been killed the night she was taken. The Tarrant County medical examiner determined that Carla had been alive for about two of the three days she was missing.

During that time, she had been beaten, sexually assaulted, and tortured. The cause of death was strangulation. She had been held somewhere by someone for two days within driving distance of her own home, and then she had been strangled and left in a drainage culvert. Then the toxicology came back, and it added something to the case that investigators could not explain away.

There was morphine in Carla’s body. She had been injected with it. Morphine in 1974 was not a street drug. It was a controlled substance that moved through a tight chain of hospitals, pharmacies, and licensed medical suppliers.

It was not something a person could pick up casually, and it was not something most people in Fort Worth could get their hands on at all. That single detail changed the shape of the crime. Whoever took Carla had access to a drug that required either a medical connection or a deliberate theft from a place that stocked it. He had also kept her alive for two days, and together those two things pointed to something colder than a spontaneous attack.

They pointed to a man with somewhere to hold a person and a reason to keep her sedated while he did. Biological evidence was collected from Carla’s body and clothing during the autopsy. Material from her bra was preserved along with her dress and the other items from the scene. In 1974, none of it could be turned into a name.

There was no technology in the world that could read a biological sample and trace it back to the person who had left it. So the evidence was cataloged, boxed, and placed into storage at the Fort Worth Police Department. The answer to who killed Carla Walker was inside that box. It would sit there unread for the next forty-six years.

The gun magazine was the strongest lead the investigators had. It was a detachable magazine for a . 22 caliber Ruger, a specific model with limited distribution. Detectives traced it through firearms purchase records and pulled the name of every recent buyer of that kind of Ruger across the Fort Worth metro.

The list was short. They started working through it, name by name. One of the buyers lived near the Brunswick Ridglea Bowl. He had purchased a .

22 Ruger that took the exact magazine found on the parking lot pavement. Within weeks of the murder, two detectives drove out to his house to talk to him. He told them the gun had been stolen out of his pickup truck about six weeks earlier. He said he had never reported the theft because he was an ex-convict and did not want the trouble.

He said he had nothing to do with the girl taken from the bowling alley, and he agreed to come downtown and sit for a polygraph. He passed the polygraph. The detectives marked him cleared and moved on. Step back and look at what the investigators were holding by the end of 1974.

They had a magazine dropped at the scene. They had traced it to a specific model of gun. They had found a man who had bought that gun, who lived near the bowling alley, and who could not produce the weapon when they asked about it. His explanation was that it had been stolen and that he had never told anyone.

And this same man was carrying a criminal record he admitted to their faces. Every piece of that should have kept him at the center of the case. Instead, one thing moved him out of it. He sat in a chair.

A machine measured his heart rate and his breathing while he answered questions, and the needle stayed calm. On the strength of that, the detectives crossed him off. A polygraph is not admissible in any courtroom in the country. It does not detect lies.

It detects stress, and it can be beaten by a person who does not feel any. The man in that chair had been to prison. He had sat across from police before. Whatever the machine was measuring that day, it was not the truth.

But in 1974, it was enough. The one lead that tied the physical evidence to a living, named person was closed on the word of a machine. The task force kept working the case through the rest of 1974. They chased every tip the public called in and pulled records on known sex offenders across Tarrant County.

Rodney McCoy was re-interviewed over and over, detectives trying to draw out anything more about the attacker’s face or voice or car. Search teams worked the route between the bowling alley and the culvert, looking for anyone who had seen a vehicle or heard a sound during the two days Carla was still alive. Nobody had seen anything. Nobody had heard anything.

A seventeen-year-old girl had been held somewhere in the city for two days, beaten and drugged and assaulted, and not one person in the surrounding community had noticed a thing. At one point, a letter arrived at the police department from someone who claimed to know who had killed Carla. It named a suspect. Detectives ran down the claim and could not verify any of it, and when they tried to trace the letter itself, that led nowhere, too.

It went into the file with the rest of the dead ends. By the end of the year, the investigation had run out of road. The magazine pointed at a man. The polygraph pointed away from him.

And so the case went quiet and stayed quiet for longer than Carla had been alive. Fort Worth in the 1970s was spreading fast across the western edge of the Dallas-Fort Worth area: hundreds of square miles of suburbs and ranch land and commercial strips. A teenager taken from a bowling alley made the local papers and the evening news, but as the months passed without an arrest, the story faded out of the headlines and out of daily conversation. Layton and Doris Walker carried their daughter’s murder for the rest of their lives, and they never got an answer.

In the year after Carla died, a local bank set up a ten-thousand-dollar reward for information that led to her killer. Nobody ever claimed it. The fund expired, and the money was returned to the people who had given it. Layton died without a name.

Doris died without a name. Both of them were buried before any lab in the country could read the evidence sitting in a box at the police department. Carla’s brother Jim was twelve years old when she was killed. He later described what came after as more than four decades of silent anger.

He buried his father without being able to tell him who had taken Carla. He buried his mother the same way. Neither grave came with an answer. The file itself sat at the Fort Worth Police Department year after year.

Detectives rotated in and out of the cold case unit as careers turned over and people retired. Each new detective who opened the Walker folder found the same walls: no suspect they could move on, no database match, no new witnesses. The only eyewitness was still Rodney McCoy, and his memory of the attacker had never been more than a white man about five feet ten swinging a pistol in the dark. There was one more shadow those years left behind, and it fell on Rodney.

He was the last person known to be with Carla and the one who walked away from the scene alive. For people who did not know the facts, that carried a quiet suspicion he could never quite shake. The biological evidence was submitted for DNA testing as the technology reached law enforcement in the late 1980s and the 1990s. But the material was too degraded.

It had been sitting in storage for more than twenty years, and the extraction methods of the day could not pull a usable profile from it. The samples went back into the box. They sat there through the 2000s. They sat there through the 2010s.

The technology kept improving, and the case kept not moving, because no public crime lab could work with what was left. In 2018, a true crime podcast covered Carla’s story and brought a new wave of attention to it. That attention reached the producers of an Oxygen Network show called The DNA of Murder with Paul Holes, and in April 2020, the case was featured on an episode. Holes was a cold case investigator who had helped identify the Golden State Killer, and after the episode aired, he connected Fort Worth detectives Leo Wagner and Jeff Bennett with a private laboratory in Texas called Astrium.

Astrium was built to do the one thing that had defeated this case for decades. It specialized in pulling usable DNA out of old, degraded, contaminated material that traditional crime labs had to give up on. The cold case unit had almost no budget for testing like this, so the show’s producers agreed to pay the roughly fifteen thousand dollars it would cost. Astrium received the biological material recovered from Carla’s bra and clothing in 1974.

It had been in storage for more than four decades, and every earlier attempt to read it had failed. Astrium had built profiles from samples older and worse than this, some of them more than a century old. This time, using extraction methods designed for exactly this kind of ruined evidence, the lab built a full genetic profile of the man who had left it. They ran the profile through public genealogy databases.

It did not match anyone directly, but it lit up a network of distant relatives who shared enough DNA to place the contributor inside one family. Genealogists began working backward through birth records, marriage records, and census data, building the family tree down toward the present, narrowing the branches. The tree closed in on three brothers who carried the McCauley name. One of them was the man who had left his DNA on Carla Walker.

When detectives pulled the records on those three brothers and cross-referenced them against the original 1974 file, one name stopped them. It was already there. Glen Samuel McCurley. The same man they had questioned in 1974 about his .

22 Ruger. The man with the stolen gun story. The man who passed the polygraph and walked out of the station back into his life for the next forty-six years. McCurley was thirty-one years old on the night Carla was taken.

He lived less than two miles from the bowling alley, in the same web of neighborhoods where Carla had grown up and gone to school. His own sons went to school with Carla’s brother Jim. For forty-six years, the man who killed her and the family that mourned her moved through the same small corner of Fort Worth, and none of them knew. His criminal record ran back more than a decade before the murder.

In 1961, at eighteen, living in a boys home, he had stolen a car from the parking lot of a bowling alley. Police chased him more than a hundred miles before they shot out his tires and caught him on foot. He served two years in prison for it. Thirteen years later, another bowling alley parking lot, another young life, and the same man walking away clean.

To confirm what the genealogy was telling them, detectives needed McCurley’s own DNA. They watched his house and collected what he threw away. From his trash, they pulled a fast food straw he had used, and they sent it to the lab. It was enough to tell them they had the right man.

Now they needed a sample that would hold up in a courtroom. On September 10th, 2020, Wagner and Bennett drove out to his house and told him the Carla Walker case had been reopened. Wagner asked if he would give a cheek swab, framing it as the simplest way to rule himself out. He hesitated.

Then he signed the consent form and let them take it. Six days later, the lab confirmed it. The DNA from his cheek was identical to the DNA recovered from Carla’s bra in 1974. The match did more than name a killer.

It cleared one, too. For forty-six years, the quiet suspicion around Rodney McCoy had never fully lifted. The DNA lifted it. He had told the truth about that night from the beginning, and the science finally proved it.

Paul Holes later said the case gave Rodney his life back. On September 21st, 2020, a United States Marshals Task Force arrived at Glen McCurley’s front door and arrested him for capital murder. When investigators searched his home, they found the . 22 Ruger.

The gun he had told two detectives was stolen from his pickup truck forty-six years earlier was inside the house. He had kept it the entire time. It had never been stolen. The story that walked him out of the station in 1974, the story the polygraph confirmed, was a lie he had carried in his own home for nearly half a century.

There was one more thing about that night that came out later. February 17th, 1974, had been McCurley’s eleventh wedding anniversary. His wife and their two children were out of town visiting family. He had no one at home, and he had no alibi, and he had days off work while Carla was missing.

Detectives said afterward that they looked at whether McCurley could be connected to other unsolved killings of young women in the Fort Worth area across the 1970s and 1980s. No further charges were ever filed, and he never talked to investigators about any other case. What they could prove was Carla. During his interrogation, detectives set a photograph of Carla Walker face up on the table in front of McCurley.

He glanced at it and said he did not know who she was. At one point he asked Detective Wagner why, if they had all this, they had not come for him back in 1974. “Because they didn’t know,” she told him, “but we do. ”

Over the hours that followed, his story came apart.

He admitted he had been out drinking that night, driving around when he saw a girl screaming in a car. He said he walked over, pulled her out after a struggle with the boyfriend, and took her. He denied the rest, and then he stopped denying it. By the end, he was crying.

“I choked her to death, I guess,” he said. He said he had been afraid she would tell on him. McCurley was charged with capital murder. Prosecutors decided not to seek the death penalty, citing his age and his health.

He was seventy-seven when he was arrested and seventy-eight by the time the trial opened in August 2021 in a Tarrant County courtroom, forty-seven years after Carla was taken. For the first days of the trial, prosecutors laid out the case that 1974 could never have built: the genealogy trail, the DNA match, which an analyst put at one in twenty-eight octillion, the recovered gun, the interrogation. His defense tried to chip at it, arguing that nothing from the crime scene itself physically tied McCurley to the attack and questioning how the confession had been drawn out of him. Against a one-in-twenty-eight-octillion match, it was not enough.

Carla’s brother, Jim, sat in the courtroom for all of it. He had been waiting since he was twelve years old. On the third day, McCurley changed his plea to guilty. The judge sentenced him to life in prison without the possibility of parole.

He was seventy-eight years old, and he had lived as a free man for nearly half a century after strangling a seventeen-year-old girl. Carla’s sister, Cindy, stood and spoke to him from the witness stand. “You had choices,” she told him. “Lots of choices that night.

And you went out to kill somebody. ” She asked him if he had done this to anyone else, to give those families the answer her own family had waited forty-seven years for. He later told a reporter he had pleaded guilty only because he had had enough hounding. He never admitted it anywhere outside that interrogation room.

He died in prison in 2023. A pistol magazine on the pavement of a bowling alley parking lot in Fort Worth. A seventeen-year-old girl pulled out of a car on the night of her Valentine’s dance and held alive for two days somewhere nobody ever found. The man who dropped that magazine sat in a police station weeks later, told a story about a stolen gun, passed a machine, and walked.

He kept that gun in his house for forty-six years, less than two miles from where Carla grew up, while her parents died without an answer and her brother carried a silent rage from the age of twelve into his fifties. The evidence that named him had been in the box the whole time. It just took the world forty-six years to learn how to read it.
