The Way a Shocking Sexual Assault and Killing Investigation Was Solved – Fifty-Eight Years Later.

In the summer of 2023, an investigator, received a request by her supervisor to review a cold case from 1967. Louisa Dunne was a elderly woman who had been sexually assaulted and killed 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 prominent labor activist, and whose home had once been a hub of civic engagement. By 1967, she was residing by herself, twice widowed but still a well-known figure in her Easton neighbourhood.

There were no witnesses to her killing, and the police investigation found few leads apart from a palm print on a rear window. Investigators canvassed 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 evidence containers,” says Smith.

She found three. “I opened the first and closed it again right away. Most of our unsolved investigations are in forensically sealed bags with barcodes. These weren’t. They just had brown cardboard luggage labels indicating what they were. It meant they’d never undergone modern forensic examinations.”

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 listing what they had. And then nothing more happened for another nearly a year. Smith pauses and tries to be diplomatic. “I was quite excited, but it wasn’t met with a huge amount 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 priority.”

It resembles the beginning of a mystery book, 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 the victim’s rape and murder and given a sentence to life.

A Record-Breaking Case

Covering 58 years, this is believed to be the longest-running unsolved investigation solved in the United Kingdom, and perhaps the globe. Later that year, the unit 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 professional decision. “He thought policing was too dangerous,” she says, “but what could be better than solving a decades-old murder?”

Smith entered the police when she was in her twenties because, she says: “I’m nosy and I was fascinated by people, in helping them when they were in crisis.” Her previous experience in child protection involved demanding hours. When she saw a job advert for a cold case investigator, she decided to pursue it. “It looked really engaging, 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 compact team set up to look at cold cases – homicides, sexual assaults, long-term missing people – and also review live cases 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 secure storage facility.

“The Louisa Dunne files had originated in a local police station, then, in the years since 1967, they moved several times 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 lead detective arrived to head up the team. DI Dave Marchant took a novel strategy. Once an aerospace engineer, Marchant had made a drastic change on his career path.

“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 try?”

The Breakthrough

In television shows, once items are sent off to forensics, the results come back in days. In actuality, the submission process and testing take a long time. “The forensic team are keen, they want to do it, but our work is always slightly on the back-burner,” 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 full DNA profile of the rapist from the victim’s clothing. A few hours later, she got a follow-up. “They had a hit on the DNA database – and it was someone who was still alive!”

Ryland Headley 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 weeks between the DNA match and Headley’s arrest, the team pored over 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 old lady’s house in 1967,” says Smith. “The accounts. The way they describe people. Today, it would usually 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 widowed twice, 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 amiss.”

Most of the team’s days were spent reading and summarising. (“Vast quantities of paperwork. It wouldn’t make great TV.”) The team also interviewed the original GP, 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 prior offenses seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in 1977 he had pleaded guilty 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 threatened to choke one and he threatened to suffocate the other with a pillow,” says Smith. Both women fought back. Though Headley was initially sentenced to life, he appealed, supported by a psychiatrist who stated that Headley was not behaving normally. “It went from a life sentence to less time,” says Smith.

Securing Justice

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 were concerned that the arrest would trigger a medical incident. “We were uncovering the darkest secret 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 contacted by family liaison. “Mary 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 often not reported now,” says Smith, “but in the mid-20th century, how many elderly ladies would ever tell anyone 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 distinct, I don’t know why,” she says. “With current investigations, the process is very reactive. With this case you’re proactive, the pressure is only from yourself. It began with me trying to get someone to take some notice of that box – and I was able to follow it right until the conclusion.”

She is certain that it is not the last resolution. There are about 130 cold cases 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 pursuing other leads. We’ll be forever opening boxes.”
