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

In the summer of 2023, a major crime review officer, was tasked by her sergeant to review the Louisa Dunne case. The victim was a elderly woman who had been sexually assaulted and killed in her Bristol home in the month of June 1967. She was a mother, a grandparent, a woman whose previous spouse had been a leading trade unionist, and whose home had once been a hub of political activity. By 1967, she was living alone, twice widowed but still a recognized figure in her local neighbourhood.

There were no witnesses to her murder, and the initial inquiry found little to go on apart from a handprint on a rear window. Police knocked on eight thousand doors and took 19,000 palm prints, but no match was found. The case remained open.

“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 archive to look at the evidence containers,” says Smith.

She found a trio. “I opened the first and closed it again right away. Most of our unsolved investigations are in forensically sealed bags with barcodes. These were not. They just had old paper tags indicating what they were. It meant they’d never been subject to modern forensic examinations.”

The rest of the day was spent with a colleague (it was his first day on the job), both gloved up, securely packaging the items and cataloging what they had. And then nothing more happened for another nearly a year. Smith hesitates and tries to be tactful. “I was quite excited, but it did not generate a huge amount of enthusiasm. Let’s just say there was some doubt as to the worth of submitting something so old to forensics. It was not considered a priority.”

It sounds like the opening chapter of a mystery book, or the premiere of a investigative series. The final outcome also seems the stuff of fiction. In the following June, a nonagenarian, Ryland Headley, was found guilty of Louisa Dunne’s rape and murder and given a sentence to life imprisonment.

A Record-Breaking Case

Covering 58 years, this is believed to be the longest-running cold case solved in the UK, and perhaps the world. Later that year, the investigative team won recognition for their work. The whole thing still feels extraordinary to her. “It just doesn’t feel real,” she says. “It’s forever giving me chills.”

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

Smith entered the police when she was in her twenties because, she says: “I’m inquisitive and I was interested in people, in helping them when they were in crisis.” Her previous experience in safeguarding involved demanding hours. When she saw a vacancy for a cold case investigator, she decided to pursue it. “It looked really interesting, it’s more of a regular hours role, so I took the position.”

Examining the Clues

Smith’s job is a non-uniformed position. The specialist unit is a small group set up to look at cold cases – murders, rapes, long-term missing people – and also re-examine live cases with fresh eyes. The original team was tasked with gathering all the old case files from around the area and moving them to a new central archive.

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

Those boxes, 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 novel strategy. Once an aerospace engineer, Marchant had “taken a hard left” on his career path.

“Cracking cases that are hard to solve – that’s my analytical approach – trying to think in new ways,” he says. “When Jo told me about the evidence, 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 testing procedure 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 complete genetic fingerprint of the rapist from the victim’s clothing. A few hours later, she got another message. “They had a match on the genetic registry – and it was someone who was living!”

Ryland Headley was 92, a widower, and living in another city. “When we realised how old he was, we didn’t have the luxury of time,” says Smith. “It was a full team effort.” In the weeks between the DNA match and Headley’s arrest, the team read every single one of the numerous original statements and records.

For a while, it was like living in two eras. “Just looking at all the photographs, seeing an the victim’s home in 1967,” says Smith. “The accounts. The way they describe people. Nowadays, it would typically be different. There are so many generational differences.”

Understanding the Victim

Smith felt she came to understand 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 wasn’t reclusive. She had a group of women who used to meet and gossip – and those were the women who realised something was very wrong.”

Most of the team’s days were spent reading and summarising. (“Vast quantities of paperwork. It wouldn’t make compelling television.”) The team also interviewed the original GP, now 89, who had been at the crime scene. “He remembered every particular 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 Pattern of Crimes

Headley’s prior offenses seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in 1977 he had admitted to assaulting two elderly women, again in their own homes. His victims’ harrowing statements from that earlier trial gave some insight 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 fought back. Though Headley was initially sentenced to life, he challenged the verdict, supported by a psychiatrist who stated that Headley was acting out of character. “It went from a life sentence to a shorter term,” says Smith.

Securing Justice

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 compelling the proof was,” she says. The team feared that the arrest would trigger a medical incident. “We were uncovering the darkest secret he’d kept hidden for sixty years,” says Smith.

Yet everything was able to go ahead. The trial took place, and the victim’s granddaughter had been contacted by specialist officers. “Mary had believed it was never going to be solved,” says Smith. For the family, there had also been a sense of shame about the nature of the crime.

“Sexual assault is massively underreported now,” says Smith, “but in the 60s and 70s, how many elderly ladies would ever tell anyone this had happened?”

Headley was told at sentencing that, for all practical purposes, he would remain incarcerated. He would spend his life behind bars.

A Lasting Impact

For Smith, it has been a unique case. “It just feels different, I don’t know why,” she says. “With current investigations, 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 interest of that evidence – and I was able to see it through right until the conclusion.”

She is confident that it won’t be the last resolution. There are about 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 sending things to forensics and pursuing other leads. We’ll be forever opening boxes.”
