How a Disturbing Sexual Assault and Killing Investigation Was Resolved – 58 Decades Later.

In the summer of 2023, Jo Smith, was asked by her sergeant to examine a decades-old murder file. Louisa Dunne was a elderly woman who had been sexually assaulted and killed in her home city home in June 1967. She was a mother of two, a grandmother, a woman whose first husband had been a prominent trade unionist, and whose home had once been a center of political activity. By 1967, she was residing by herself, twice widowed but still a recognized presence in her local neighbourhood.

There were no one who saw anything to her killing, and the initial inquiry found few leads apart from a handprint on a back window. Investigators knocked on 8,000 doors and took 19,000 palm prints, but no identification was found. The case stayed unsolved.

“Upon realizing 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 three. “I opened the first and closed it again immediately. Most of our cold cases 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, forensically bagging the items and cataloging what they had. And then there was no progress for another nearly a year. Smith pauses 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 doubt as to the value of submitting something so old to forensics. It wasn’t seen as a high-priority matter.”

It sounds like the opening chapter of a mystery book, or the premiere of a investigative series. The end result also seems the material for a story. 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 Case

Spanning 58 years, this is believed to be the longest-running unsolved investigation closed in the UK, and perhaps the world. Later that year, the unit won recognition for their work. The whole thing still feels remarkable to her. “It just doesn’t feel real,” she says. “It’s forever giving me goose bumps.”

For Smith, cases like this are confirmation that she made the right career choice. “He thought 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 nosy and I was interested in people, in helping them when they were in distress.” Her previous role in child protection involved demanding hours. When she saw a job advert for a crime review officer, she decided to pursue it. “It looked really engaging, it’s more of a standard schedule role, so here I am.”

Revisiting the Evidence

Smith’s job is a civilian role. The specialist unit is a compact team set up to look at cold cases – homicides, rapes, long-term missing people – and also re-examine active investigations with a new perspective. The original team was tasked with collecting 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 precinct, then, in the years since 1967, they moved 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 lead the team. DI Dave Marchant took a different approach. Once an aerospace engineer, Marchant had “taken a hard left” on his career path.

“Solving problems that are hard to solve – that’s my engineering mindset – trying to think in new ways,” 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 cold case crime dramas, once items are sent off to forensics, the results come back in days. In real life, the testing procedure and testing take a long time. “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 precedence.”

It was the end of August 2024 when Smith received a message that forensics had a complete genetic fingerprint of the rapist from the victim’s clothing. A few hours later, she got a follow-up. “They had a hit on the genetic registry – and it was someone who was living!”

The suspect was ninety-two, widowed, and living in Ipswich. “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 period 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 time periods. “Just looking at all the photos, seeing an the victim’s home in 1967,” says Smith. “The witness statements. 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. “Louisa was such a prominent person,” she says. “Lots of people were saying that they saw her outside her home every day. She was widowed twice, estranged 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 spoke with the original GP, now eighty-nine, 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 History of Violence

Headley’s previous convictions seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in the late 1970s he had pleaded guilty to assaulting two elderly women, again in their own homes. His victims’ harrowing statements from that previous case 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 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 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 identified and approached by family liaison. “She 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.

“Rape 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 practical 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. “With current investigations, the process is very reactive. With this case you’re driving the inquiry, 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 see it through right until the end.”

She is confident that it won’t be the last resolution. There are approximately one hundred and thirty 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 submitting evidence to forensics and following other leads. We’ll be forever unlocking the past.”
