The Way a Appalling Sexual Assault and Killing Investigation Was Cracked – 58 Years Later.

In June 2023, an investigator, was tasked by her supervisor to review 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 grandmother, a woman whose first husband had been a prominent trade unionist, and whose home had once been a hub of political activity. By 1967, she was living alone, twice widowed but still a familiar presence in her local neighbourhood.

There were no one who saw anything to her killing, and the initial inquiry discovered little to go on apart from a palm print on a rear window. Investigators knocked on 8,000 doors and took nineteen thousand palm prints, but no match was found. The case remained open.

“Upon realizing 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 evidence containers,” says Smith.

She found three. “I opened the first and closed it again immediately. Most of our unsolved investigations are in sterile evidence bags with identification codes. These weren’t. They just had brown cardboard luggage labels saying what they were. It meant they’d never undergone modern scientific testing.”

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 nearly a year. Smith hesitates and tries to be tactful. “I was very enthusiastic, but it did not generate a huge amount of enthusiasm. Let’s just 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 beginning of a mystery book, or the premiere of a cold case TV drama. The end result also seems the material for a story. In the following June, a nonagenarian, Ryland Headley, was found guilty of Louisa Dunne’s rape and murder and given a sentence to life.

A Record-Breaking Case

Spanning fifty-eight years, this is believed to be the longest-running unsolved investigation solved in the UK, and perhaps the world. 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. “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 24 because, she says: “I’m nosy and I was interested in people, in helping them when they were in distress.” Her previous role in safeguarding involved grueling hours. When she saw a vacancy for a crime review officer, she decided to pursue it. “It looked really interesting, 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 cold cases – homicides, sexual assaults, long-term missing people – and also review active investigations with a new perspective. The original team was tasked with collecting all the old case files from around the region and relocating them to a new central archive.

“The Louisa Dunne files 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 properly secured, returned to storage. Towards the end of 2023, a new lead detective arrived to head up the team. DI Dave Marchant took a different approach. Once an engineer, Marchant had “taken a hard left” on his professional journey.

“Cracking cases that are hard to solve – that’s my engineering mindset – trying to think in new ways,” he says. “When Jo told me about the box, 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 submission process and testing take a long time. “The laboratory scientists are interested, they want to do it, but our work is always slightly on the back-burner,” says Smith. “Current investigations have to take priority.”

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 skirt. A few hours later, she got another message. “They had a hit on the genetic registry – and it was someone who was living!”

The suspect was 92, a widower, and living in Ipswich. “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 period between the DNA match and Headley’s arrest, the team pored over every single one of the numerous original accounts and records.

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

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 outside her home every day. She was twice widowed, estranged from her family, but she remained social. 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 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 haunts you.’”

A History of Crimes

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 admitted 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 choke one and he threatened to suffocate the other with a pillow,” 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 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 strong the evidence was,” she says. The team were concerned that the arrest would trigger a medical incident. “We were uncovering the darkest secret he’d kept hidden for 60 years,” says Smith.

Yet everything was able to go ahead. The court case took place, and the victim’s living relative had been contacted by family liaison. “Mary had assumed it was never going to be resolved,” says Smith. For the family, there had also been a sense of shame about the nature of the crime.

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

Headley was told at sentencing that, for all intents and purposes, he would remain incarcerated. 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 reactive. 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 interest of that evidence – and I was able to see it through right until the conclusion.”

She is confident that it won’t be the last resolution. There are about 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 pursuing other leads. We’ll be forever unlocking the past.”
