How a Shocking Sexual Assault and Killing Investigation Was Cracked – Fifty-Eight Decades Later.

In June 2023, an investigator, was tasked by her supervisor to examine the Louisa Dunne case. Louisa Dunne was a elderly woman who had been raped and murdered in her home city home in the month of June 1967. She was a parent of two children, a grandparent, a woman whose previous spouse had been a leading trade unionist, and whose home had once been a hub of civic engagement. By 1967, she was living alone, having lost two husbands but still a well-known figure in her local neighbourhood.

There were no witnesses to her murder, and the police investigation discovered few leads apart from a palm print on a rear window. Officers knocked on 8,000 doors and took nineteen thousand 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 forensics, so I went to the archive to look at the evidence containers,” says Smith.

She found a trio. “I opened the first and put the lid back on again immediately. Most of our cold cases are in sterile evidence bags with barcodes. These were not. They just had old paper tags saying what they were. It meant they’d never undergone 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, forensically bagging the items and cataloging what they had. And then there was no progress for another eight months. Smith pauses and tries to be diplomatic. “I was quite excited, but it did not generate 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 high-priority matter.”

It sounds like the beginning of a crime novel, or the premiere of a investigative series. The final outcome also seems the stuff of fiction. In the following June, a 92-year-old man, Ryland Headley, was found culpable of Louisa Dunne’s rape and murder and sentenced to life imprisonment.

A Record-Breaking Investigation

Covering 58 years, this is believed to be the oldest unsolved investigation closed in the UK, and perhaps the globe. Subsequently, the unit won an award 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 proof 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 joined the police when she was 24 because, she says: “I’m inquisitive and I was interested in people, in assisting them when they were in crisis.” Her previous role 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.”

Revisiting the Evidence

Smith’s job is a non-uniformed position. The major crime review team is a small group set up to look at historical crimes – homicides, rapes, disappearances – and also review live cases with fresh eyes. The original team was tasked with collecting all the old case files from around the area 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 to multiple locations before finally arriving at the archive,” says Smith.

Those boxes, their contents now properly secured, returned to storage. Towards the end of 2023, a new senior investigating officer arrived to head up 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 challenging – 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 try?”

The Key Discovery

In television shows, once items are sent off to forensics, the results come back quickly. In real life, the testing procedure and testing take many months. “The forensic team are keen, they want to do it, but our work is always slightly on the lower priority,” says Smith. “Live-time murders have to take precedence.”

It was the end of August 2024 when Smith received a notification that forensics had a complete genetic fingerprint of the assailant from the victim’s clothing. A few hours later, she got another message. “They had a match on the DNA database – and it was someone who was living!”

The suspect was 92, 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 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 living in two time periods. “Just looking at all the photographs, seeing an the victim’s home in 1967,” says Smith. “The witness statements. The way they portray people. Nowadays, it would usually be different. There are so many changes over time.”

Getting to Know the Victim

Smith felt she got to know the victim, too. “She was such a big character,” she says. “Lots of people were saying that they saw her outside her home every day. She was widowed twice, separated from her family, but she wasn’t reclusive. 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 reading and summarising. (“Humongous amounts of paperwork. It wouldn’t make great TV.”) The team also interviewed the doctor, now eighty-nine, who had attended the 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 History of Violence

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

“He threatened to choke one and he threatened to smother the other with a cushion,” says Smith. Both women fought back. Though Headley was initially sentenced to life, he appealed, supported by a mental health professional who stated that Headley was not behaving normally. “It went from a life sentence to a shorter term,” 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 compelling the proof was,” she says. The team feared that the arrest would trigger a health crisis. “We were uncovering the darkest secret he’d kept hidden for sixty years,” says Smith.

Yet everything was able to proceed. The trial took place, and the victim’s living relative had been contacted by specialist officers. “Mary had assumed it was never going to be solved,” says Smith. For the family, there had also been a stigma about the nature of the crime.

“Rape is massively underreported 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 intents and purposes, he would never be released. 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 proactive, the urgency 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 cold cases in the archives. “We’ve got so much more to do,” she says. “We have a number of murders that we’re reviewing – we’re constantly sending things to forensics and pursuing other leads. We’ll be forever unlocking the past.”
