How a Shocking Sexual Assault and Killing Investigation Was Solved – Fifty-Eight Years After.

In the summer of 2023, an investigator, received a request by her supervisor to examine a decades-old murder file. The victim was a 75-year-old woman who had been sexually assaulted and killed in her Bristol home in June 1967. She was a mother, a grandparent, a woman whose previous spouse had been a leading labor activist, and whose home had once been a center of political activity. By 1967, she was residing by herself, twice widowed but still a recognized figure in her local neighbourhood.

There were no one who saw anything to her murder, and the initial inquiry found few leads apart from a handprint on a back window. Officers knocked on eight thousand doors and took nineteen thousand palm prints, but no identification was found. The case stayed unsolved.

“When I saw that it was dated 1967, I knew we were only going to solve this through scientific analysis, so I went to the storage facility to look at the exhibits boxes,” says Smith.

She found three. “I opened the first and closed it again right away. Most of our cold cases are in forensically sealed bags with identification codes. These weren’t. They just had old paper tags saying what they were. It meant they’d never been subject to modern forensic examinations.”

The rest of the day was spent with a co-worker (it was his initial day on the job), both wearing protective gloves, securely packaging the items and listing what they had. And then nothing more happened for another nearly a year. Smith pauses and tries to be diplomatic. “I was quite excited, but it wasn’t met with a great deal of enthusiasm. Let’s just say there was some scepticism as to the value of submitting something so old to forensics. It was not considered a priority.”

It resembles the beginning of a crime novel, or the first episode of a investigative series. The end result also seems the material for a story. In the following June, a nonagenarian, the defendant, was found guilty of the victim’s rape and murder and given a sentence to life imprisonment.

A Record-Breaking Case

Spanning 58 years, this is believed to be the longest-running unsolved investigation solved in the UK, and perhaps the world. Subsequently, the unit won recognition for their work. The whole thing still feels remarkable to her. “It just doesn’t feel real,” she says. “It’s forever giving me chills.”

For Smith, cases like this are proof that she made the right professional decision. “My father believed policing was too dangerous,” she says, “but what could be better than solving a decades-old murder?”

Smith joined the police when she was in her twenties because, she says: “I’m inquisitive and I was fascinated by people, in assisting them when they were in crisis.” Her previous experience in safeguarding involved grueling hours. When she saw a vacancy for a cold case investigator, she decided to apply. “It looked really interesting, it’s more of a standard schedule role, so I took the position.”

Revisiting the Evidence

Smith’s job is a non-uniformed position. The specialist unit is a compact team set up to look at cold cases – murders, sexual assaults, disappearances – and also review active investigations with a new perspective. The original team was tasked with gathering all the old case files from around the region and relocating them to a new secure storage facility.

“The Louisa Dunne files had started in a precinct, then, in the years since 1967, they were transferred to multiple locations before finally coming here,” says Smith.

Those containers, their contents now forensically bagged, returned to storage. Towards the end of 2023, a new lead detective arrived to lead the team. DI Dave Marchant took a different approach. Once an aerospace engineer, Marchant had “taken a hard left” on his career path.

“Cracking cases that are challenging – that’s my engineering mindset – trying to think in new ways,” he says. “When Jo told me about the box, it was an obvious decision. Why wouldn’t we try?”

The Key Discovery

In cold case crime dramas, once items are sent off to forensics, the results come back quickly. In real life, the submission process and testing take a long time. “The forensic team are interested, they want to do it, but our work is always slightly on the back-burner,” says Smith. “Current investigations have to take priority.”

It was the end of August 2024 when Smith received a notification that forensics had a full DNA profile of the assailant from the victim’s skirt. A few hours later, she got another message. “They had a hit on the genetic registry – and it was someone who was still alive!”

Ryland Headley was ninety-two, a widower, and living in another city. “When we realised how old he was, we didn’t have the time to waste,” says Smith. “It was all hands on deck.” In the weeks between the DNA match and Headley’s arrest, the team read every single one of the numerous original accounts and records.

For a while, it was like navigating two eras. “Just looking at all the photographs, seeing an the victim’s home in 1967,” says Smith. “The accounts. The way they portray people. Nowadays, it would usually be different. There are so many changes over time.”

Understanding the Victim

Smith felt she got to know the victim, too. “Louisa was such a prominent person,” she says. “Lots of people were saying that they saw her on the doorstep every day. She was twice widowed, estranged from her family, but she remained social. She had a gaggle of women who used to meet and gossip – and those were the women who realised something was amiss.”

Most of the team’s days were spent analyzing documents. (“Humongous amounts of paperwork. It wouldn’t make great TV.”) The team also spoke with the doctor, now 89, who had been at the crime scene. “He remembered every detail from that day,” says Smith. “He said: ‘I’ve been a doctor all my life and seen a lot of dead bodies but that’s the only one that had been murdered. That stays with you.’”

A History of Violence

Headley’s previous convictions seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in 1977 he had pleaded guilty to assaulting two elderly women, again in their own homes. His victims’ harrowing statements from that previous case gave some idea into the victim’s last moments.

“He menaced to strangle one and he threatened to suffocate the other with a cushion,” says Smith. Both women resisted. Though Headley was initially sentenced to life, he appealed, supported by a mental health professional who stated that Headley was acting out of character. “It went from a life sentence to less time,” says Smith.

Closing the Case

Smith was there for Headley’s arrest. “I knew what he looked like, I knew he was going to be 92, and I also knew how strong the evidence was,” she says. The team were concerned that the arrest would trigger a health crisis. “We were uncovering the most hidden truth he’d kept hidden for 60 years,” says Smith.

Yet everything was able to go ahead. The trial took place, and the victim’s living relative had been identified and approached by family liaison. “Mary had assumed it was never going to be resolved,” says Smith. For the family, there had also been a stigma about the nature of the crime.

“Rape is often not reported now,” says Smith, “but in the 60s and 70s, how many older women would ever report this had happened?”

Headley was told at sentencing that, for all practical purposes, he would never be released. He would die in prison.

A Profound Effect

For Smith, it has been a special case. “It just feels different, I don’t know why,” she says. “In a live case, the process is very responsive. With this case you’re driving the inquiry, the pressure is only from yourself. It began with me trying to get someone to take some notice of that evidence – and I was able to follow it right until the conclusion.”

She is confident that it is not the last solved case. There are approximately one hundred and thirty unsolved investigations in the archives. “We’ve got so much more to do,” she says. “We have several murders that we’re re-examining – we’re constantly submitting evidence to forensics and following other leads. We’ll be forever unlocking the past.”
