How a Appalling Rape and Murder Investigation Was Resolved – Fifty-Eight Decades Later.

In the summer of 2023, an investigator, was asked by her sergeant to review the Louisa Dunne case. The woman was a 75-year-old 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 leading trade unionist, and whose home had once been a center of political activity. By 1967, she was residing by herself, having lost two husbands 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 rear window. Police canvassed 8,000 doors and took 19,000 palm prints, but no identification was found. The case remained open.

“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 the officer.

She found three. “I opened the first and put the lid back on again immediately. Most of our unsolved investigations are in forensically sealed bags with identification codes. These were not. They just had old paper tags 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 first day on the job), both wearing protective gloves, securely packaging the items and listing 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 did not generate a great deal of enthusiasm. It’s fair to say there was some scepticism as to the value of submitting something that aged to forensics. It was not considered a high-priority matter.”

It resembles the opening chapter of a crime novel, or the premiere of a cold case TV drama. The end result also seems the stuff of fiction. In June, a nonagenarian, Ryland Headley, was found guilty of Louisa Dunne’s rape and murder and sentenced to life imprisonment.

An Unprecedented Case

Spanning 58 years, this is believed to be the longest-running cold case closed in the United Kingdom, and perhaps the world. Subsequently, the investigative team won an award for their work. The whole thing still feels remarkable to her. “It just doesn’t feel tangible,” she says. “It’s forever giving me chills.”

For Smith, cases like this are proof that she made the correct professional decision. “My father believed policing was too risky,” she says, “but what could be better than resolving a 58-year-old murder?”

Smith joined the police when she was in her twenties because, she says: “I’m inquisitive and I was fascinated by people, in assisting them when they were in crisis.” Her previous experience in safeguarding involved grueling hours. When she saw a job advert for a cold case investigator, she decided to apply. “It looked really interesting, it’s more of a regular hours role, so I took the position.”

Examining the Evidence

Smith’s job is a non-uniformed position. The specialist unit is a compact team set up to look at cold cases – homicides, sexual assaults, long-term missing people – and also review live cases with fresh eyes. 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 to multiple locations 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 head up the team. The new officer took a novel strategy. Once an aerospace 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 obvious decision. Why wouldn’t we try?”

The Key Discovery

In cold case crime dramas, once items are sent off to forensics, the results come back quickly. In real life, the submission process and testing take many months. “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 priority.”

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 skirt. A few hours later, she got another message. “They had a hit on the DNA database – and it was someone who was still alive!”

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 all hands on deck.” In the period 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 navigating two time periods. “Just looking at all the photos, seeing an old lady’s house in 1967,” says Smith. “The accounts. The way they describe people. Nowadays, it would usually be different. There are so many changes over time.”

Understanding the Victim

Smith felt she came to understand 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 widowed twice, separated from her family, but she remained social. She had a group 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 reading and summarising. (“Humongous amounts of paperwork. It wouldn’t make great TV.”) The team also spoke with the doctor, now 89, who had been at the crime scene. “He remembered every detail from that day,” says Smith. “He said: ‘In my career 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 Crimes

Headley’s previous convictions seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in 1977 he had pleaded guilty to raping two older women, again in their own homes. His victims’ harrowing statements from that earlier trial gave some idea into the victim’s last moments.

“He menaced to strangle one and he threatened to suffocate the other with a cushion,” says Smith. Both women fought back. 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 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 feared that the arrest would trigger a health crisis. “We were uncovering the most hidden truth he’d kept hidden for 60 years,” says Smith.

Yet everything was able to go ahead. The trial took place, and the victim’s granddaughter had been contacted by family liaison. “Mary had assumed 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 spend his life behind bars.

A Profound Effect

For Smith, it has been a special 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 notice of that box – and I was able to see it through right until the conclusion.”

She is certain that it is not the last solved case. There are about one hundred and thirty unsolved investigations 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 following other lines of inquiry. We’ll be forever unlocking the past.”
