How a Shocking Rape and Murder Investigation Was Solved – Fifty-Eight Years Later.

In the summer of 2023, an investigator, was asked by her supervisor to “take a look at” a cold case from 1967. Louisa Dunne was a 75-year-old woman who had been sexually assaulted and killed in her home city home in June 1967. She was a parent of two children, a grandmother, a woman whose previous spouse had been a leading labor activist, and whose home had once been a center of civic engagement. By 1967, she was living alone, twice widowed but still a familiar figure in her local neighbourhood.

There were no one who saw anything to her murder, and the police investigation discovered little to go on apart from a handprint on a rear window. Investigators knocked on eight thousand doors and took nineteen thousand palm prints, but no identification was found. The case stayed 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 three. “I opened the first and put the lid back on again immediately. Most of our unsolved investigations are in sterile evidence bags with barcodes. These weren’t. They just had brown cardboard luggage labels 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 initial day on the job), both wearing protective gloves, forensically bagging the items and listing what they had. And then nothing more happened for another eight months. Smith pauses and tries to be tactful. “I was quite excited, but it wasn’t met with a great deal 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 priority.”

It sounds like 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 the following June, a 92-year-old man, Ryland Headley, was found guilty of Louisa Dunne’s rape and murder and sentenced to life imprisonment.

A Record-Breaking Investigation

Spanning 58 years, this is believed to be the longest-running cold case closed in the UK, and possibly the globe. Subsequently, the investigative team won recognition for their work. The whole thing still feels extraordinary to her. “It just doesn’t feel tangible,” she says. “It’s forever giving me goose bumps.”

For Smith, cases like this are proof that she made the right career choice. “My father believed policing was too risky,” 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 interested in people, in assisting them when they were in distress.” Her previous role in safeguarding involved grueling hours. When she saw a job advert for a crime review officer, she decided to apply. “It looked really interesting, it’s more of a standard schedule role, so here I am.”

Examining the Evidence

Smith’s job is a civilian role. The major crime review team is a compact team set up to look at historical crimes – homicides, sexual assaults, long-term missing people – and also re-examine active investigations with a new perspective. The original team was tasked with gathering all the old case files from around the region 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 moved several times before finally coming here,” says Smith.

Those containers, their contents now forensically bagged, 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 aerospace engineer, Marchant had “taken a hard left” on his professional journey.

“Solving problems that are challenging – that’s my engineering mindset – trying to think in innovative manners,” he says. “When Jo told me about the box, it was an obvious decision. Why wouldn’t we give it a go?”

The Breakthrough

In cold case crime dramas, once items are sent off to forensics, the results come back in days. In actuality, 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. “Current investigations have to take precedence.”

It was the end of August 2024 when Smith received a message 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 hit on the genetic registry – and it was someone who was still alive!”

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 period 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 eras. “Just looking at all the photos, seeing an the victim’s home in 1967,” says Smith. “The accounts. The way they portray people. Today, it would usually be different. There are so many generational differences.”

Getting to Know the Victim

Smith felt she got to know the victim, too. “Louisa was such a big character,” she says. “Lots of people were saying that they saw her on the doorstep every day. She was twice widowed, 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 very wrong.”

Most of the team’s days were spent analyzing documents. (“Vast quantities of paperwork. It wouldn’t make compelling television.”) The team also interviewed the doctor, now 89, 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 haunts 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 admitted to raping two older women, again in their own homes. His victims’ harrowing statements from that previous case gave some idea into the victim’s last moments.

“He threatened to strangle 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 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 health crisis. “We were uncovering the darkest secret he’d kept hidden for sixty years,” says Smith.

Yet everything was able to go ahead. 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 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 intents and purposes, he would remain incarcerated. 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 reactive. With this case you’re driving the inquiry, the pressure is only from yourself. It started with me trying to get someone to take some interest of that evidence – and I was able to follow it right until the end.”

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