The Way a Appalling Sexual Assault and Killing Case Was Cracked – 58 Decades Later.

In the summer of 2023, an investigator, was asked by her supervisor to examine a cold case from 1967. Louisa Dunne was a elderly woman who had been sexually assaulted and killed in her Bristol home in the month of June 1967. She was a mother, a grandmother, a woman whose previous spouse had been a prominent labor activist, and whose home had once been a hub of political activity. By 1967, she was residing by herself, having lost two husbands but still a recognized figure in her Easton neighbourhood.

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

“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 storage facility to look at the evidence containers,” states the officer.

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 indicating 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, securely packaging the items and cataloging what they had. And then nothing more happened for another eight months. Smith pauses 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 worth of submitting something so old to forensics. It wasn’t seen as a priority.”

It resembles 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 culpable of the victim’s rape and murder and sentenced to life imprisonment.

An Unprecedented Investigation

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

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

Smith entered the police when she was 24 because, she says: “I’m inquisitive and I was fascinated by people, in helping them when they were in crisis.” Her previous role in safeguarding involved demanding hours. When she saw a vacancy for a crime review officer, she decided to apply. “It looked really interesting, it’s more of a regular hours role, so I took the position.”

Revisiting the Evidence

Smith’s job is a civilian role. The major crime review team is a small group set up to look at historical crimes – murders, rapes, disappearances – 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 area and relocating them to a new secure storage facility.

“The Louisa Dunne files had started in a precinct, then, in the years since 1967, they were transferred several times before finally coming here,” says Smith.

Those boxes, their contents now forensically bagged, 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 engineer, Marchant had made a drastic change on his career path.

“Cracking cases that are challenging – that’s my engineering mindset – trying to think in new ways,” he says. “When Jo told me about the evidence, it was an obvious decision. 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 quickly. In actuality, the testing procedure and testing take many months. “The laboratory scientists 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 message that forensics had a full DNA profile of the rapist from the victim’s clothing. A few hours later, she got another message. “They had a hit on the DNA database – and it was someone who was still alive!”

Ryland Headley was ninety-two, a widower, 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 weeks 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 living in two eras. “Just looking at all the photographs, seeing an old lady’s house in 1967,” says Smith. “The accounts. The way they describe people. Today, it would typically be different. There are so many changes over time.”

Understanding the Victim

Smith felt she got to know the victim, too. “She was such a prominent person,” she says. “Lots of people were saying that they saw her on the doorstep every day. She was widowed twice, estranged 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 amiss.”

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 89, who had been at the crime scene. “He remembered every detail 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 Pattern of Crimes

Headley’s prior offenses seemed to leave little question 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’ disturbing statements from that previous case gave some insight into the victim’s last moments.

“He threatened to strangle one and he threatened to smother the other with a pillow,” says Smith. Both women resisted. Though Headley was initially sentenced to life, he appealed, supported by a psychiatrist who stated that Headley was acting out of character. “It went from a life sentence to less time,” says Smith.

Closing the Case

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 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 specialist officers. “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.

“Sexual assault 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 remain incarcerated. He would die in prison.

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 proactive, 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 certain that it is not the last solved case. There are approximately one hundred and thirty cold cases in the archives. “We’ve got so much more to do,” she says. “We have several murders that we’re reviewing – we’re constantly sending things to forensics and pursuing other leads. We’ll be forever unlocking the past.”
