The Way a Disturbing Sexual Assault and Killing Case Was Solved – Fifty-Eight Years Later.

In June 2023, a major crime review officer, was asked by her sergeant to review the Louisa Dunne case. The woman was a 75-year-old woman who had been sexually assaulted and killed in her home city home in June 1967. She was a mother, a grandmother, a woman whose first husband had been a leading labor activist, and whose home had once been a hub of political activity. By 1967, she was residing by herself, having lost two husbands but still a familiar presence in her Easton neighbourhood.

There were no witnesses to her murder, and the police investigation found few leads apart from a handprint on a back window. Investigators canvassed eight thousand doors and took 19,000 palm prints, but no match was found. The case stayed unsolved.

“When I saw that it was dated 1967, I knew we were only going to solve this through forensics, so I went to the archive to look at the evidence containers,” states Smith.

She found a trio. “I opened the first and put the lid back on again right away. Most of our unsolved investigations are in forensically sealed bags with barcodes. These were not. They just had brown cardboard luggage labels indicating what they were. It meant they’d never undergone modern scientific testing.”

The rest of the day was spent with a colleague (it was his initial day on the job), both gloved up, forensically bagging the items and listing what they had. And then nothing more happened for another eight months. Smith hesitates and tries to be tactful. “I was very enthusiastic, but it wasn’t met with a great deal of enthusiasm. Let’s just say there was some scepticism as to the worth of submitting something that aged to forensics. It was not considered a priority.”

It sounds like the beginning of a mystery book, or the premiere of a investigative series. The end result also seems the material for a story. In June, a nonagenarian, Ryland Headley, was found guilty of Louisa Dunne’s rape and murder and sentenced to life.

An Unprecedented Case

Spanning fifty-eight years, this is believed to be the longest-running unsolved investigation solved in the United Kingdom, and perhaps the globe. Later that year, the investigative team won an award for their work. The whole thing still feels extraordinary to her. “It just doesn’t feel tangible,” she says. “It’s forever giving me chills.”

For Smith, cases like this are proof that she made the right career choice. “He thought policing was too risky,” she says, “but what could be better than solving a 58-year-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 assisting them when they were in crisis.” Her previous role in child protection involved grueling hours. When she saw a job advert for a cold case investigator, she decided to pursue it. “It looked really engaging, it’s more of a standard schedule role, so I took the position.”

Examining the Evidence

Smith’s job is a civilian role. The specialist unit is a compact team set up to look at historical crimes – murders, rapes, long-term missing people – and also review live cases with fresh eyes. The original team was tasked with gathering all the old case files from around the area and relocating them to a new secure storage facility.

“The case documents had originated 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 head up the team. DI Dave Marchant took a novel strategy. Once an engineer, Marchant had “taken a hard left” on his professional journey.

“Solving problems that are hard to solve – that’s my analytical approach – trying to think in innovative manners,” he says. “When Jo told me about the evidence, it was an absolute no-brainer. Why wouldn’t we try?”

The Breakthrough

In television shows, once items are sent off to forensics, the results come back quickly. In actuality, the submission process and testing take many months. “The laboratory scientists are keen, they want to do it, but our work is always slightly on the lower priority,” 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 clothing. A few hours later, she got a follow-up. “They had a match on the DNA database – and it was someone who was living!”

The suspect was 92, widowed, 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 thousands original statements and records.

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

Getting to Know the Victim

Smith felt she came to understand the victim, too. “She was such a prominent person,” she says. “Lots of people were saying that they saw her on the doorstep every day. She was widowed twice, 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 great TV.”) The team also spoke with the original GP, 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 Pattern of Violence

Headley’s prior offenses seemed to leave little doubt of his guilt. After the 1967 murder, he had moved, and in the late 1970s he had admitted to raping two elderly women, again in their own homes. His victims’ disturbing statements from that earlier trial gave some insight into the victim’s last moments.

“He menaced to strangle one and he threatened to smother the other with a cushion,” says Smith. Both women resisted. 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 less time,” says Smith.

Closing the Case

Smith was present at 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 medical incident. “We were uncovering the most hidden truth he’d kept hidden for sixty 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. “She had assumed 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 older women would ever tell anyone this had happened?”

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

A Profound Effect

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

She is certain that it is not the last solved case. There are approximately 130 unsolved investigations in the archives. “We’ve got so much more to do,” she says. “We have several murders that we’re reviewing – we’re constantly submitting evidence to forensics and following other lines of inquiry. We’ll be forever opening boxes.”
