How a Shocking Sexual Assault and Killing Case Was Resolved – Fifty-Eight Years After.

In June 2023, an investigator, was asked by her team leader to examine the Louisa Dunne case. The woman was a 75-year-old woman who had been sexually assaulted and killed in her Bristol home in June 1967. She was a parent of two children, a grandmother, a woman whose previous spouse had been a leading trade unionist, and whose home had once been a focal point 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 one who saw anything to her killing, and the initial inquiry unearthed few leads apart from a handprint on a rear window. Investigators knocked on 8,000 doors and took nineteen thousand 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 scientific analysis, so I went to the archive to look at the exhibits boxes,” states the officer.

She found three. “I opened the first and closed it again immediately. Most of our unsolved investigations are in forensically sealed bags with identification codes. These weren’t. They just had old paper tags 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 cataloging what they had. And then nothing more happened for another eight months. Smith hesitates and tries to be tactful. “I was quite excited, but it did not generate a huge amount of enthusiasm. It’s fair to say there was some scepticism as to the value of submitting something so old to forensics. It wasn’t seen as a high-priority matter.”

It resembles the opening chapter of a crime novel, or the first episode of a cold case TV drama. The end result also seems the material for a story. In June, a nonagenarian, Ryland Headley, was found culpable of Louisa Dunne’s rape and murder and sentenced to life.

A Record-Breaking Case

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

For Smith, cases like this are confirmation that she made the right professional decision. “My father believed policing was too dangerous,” she says, “but what could be better than resolving a 58-year-old murder?”

Smith entered the police when she was in her twenties because, she says: “I’m inquisitive and I was fascinated by people, in helping them when they were in crisis.” Her previous experience in safeguarding involved grueling hours. When she saw a job advert for a crime review officer, she decided to apply. “It looked really engaging, it’s more of a standard schedule role, so here I am.”

Revisiting the Clues

Smith’s job is a non-uniformed position. The major crime review team is a small group set up to look at cold cases – murders, sexual assaults, long-term missing people – and also re-examine active investigations with fresh eyes. The original team was tasked with gathering all the old case files from around the region and relocating them to a new central archive.

“The case documents had started in a precinct, then, in the years since 1967, they were transferred several times before finally coming here,” says Smith.

Those boxes, their contents now properly secured, returned to storage. Towards the end of 2023, a new senior investigating officer arrived to lead the team. DI Dave Marchant took a different approach. Once an engineer, Marchant had made a drastic change on his career path.

“Solving problems that are hard to solve – that’s my engineering mindset – 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 give it a go?”

The Key Discovery

In television shows, once items are sent off to forensics, the results come back in days. In actuality, the testing procedure and testing take many months. “The laboratory scientists are interested, 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 rapist from the victim’s skirt. A few hours later, she got another message. “They had a match on the genetic registry – and it was someone who was still alive!”

The suspect was ninety-two, widowed, 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 thousands original accounts and records.

For a while, it was like navigating two time periods. “Just looking at all the photos, seeing an old lady’s house in 1967,” says Smith. “The accounts. The way they portray people. Nowadays, it would typically be different. There are so many changes over time.”

Getting to Know 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 outside her home 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. (“Humongous amounts 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 History 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 assaulting two older women, again in their own homes. His victims’ disturbing statements from that earlier trial gave some idea into the victim’s last moments.

“He menaced to choke one and he threatened to smother the other with a pillow,” says Smith. Both women fought back. Though Headley was initially sentenced to life, he challenged the verdict, 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.

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 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 sixty years,” says Smith.

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

“Sexual assault is often not reported now,” says Smith, “but in the mid-20th century, how many elderly ladies would ever report this had happened?”

Headley was told at sentencing that, for all practical purposes, he would never be released. He would spend his life behind bars.

A Profound Effect

For Smith, it has been a unique case. “It just feels distinct, 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 notice of that evidence – and I was able to see it through right until the end.”

She is certain that it won’t be the last resolution. 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 re-examining – we’re constantly submitting evidence to forensics and following other leads. We’ll be forever opening boxes.”
