How a Shocking Sexual Assault and Killing Investigation Was Cracked – 58 Years After.

In June 2023, an investigator, received a request by her supervisor to “take a look at” the Louisa Dunne case. The woman 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 of two, a grandmother, a woman whose first husband had been a prominent labor activist, and whose home had once been a hub of civic engagement. By 1967, she was residing by herself, having lost two husbands but still a well-known presence in her local neighbourhood.

There were no witnesses to her killing, and the initial inquiry found little to go on apart from a palm print on a back window. Police knocked on 8,000 doors and took 19,000 palm prints, but no match was found. The case stayed open.

“When I saw 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 exhibits boxes,” says the officer.

She found three. “I opened the first and closed it again immediately. Most of our cold cases are in sterile evidence bags with identification codes. These weren’t. They just had old paper tags saying what they were. It meant they’d never been subject to modern scientific testing.”

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 nothing more happened for another eight months. Smith pauses and tries to be diplomatic. “I was quite excited, but it wasn’t met with a huge amount of enthusiasm. It’s fair to 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 resembles the opening chapter of a mystery book, or the first episode of a investigative series. The end result also seems the stuff of fiction. In the following June, a nonagenarian, the defendant, 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 cold case closed in the United Kingdom, and possibly the world. 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. “He thought policing was too dangerous,” she says, “but what could be better than solving a decades-old murder?”

Smith joined 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 distress.” Her previous experience in safeguarding 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 here I am.”

Revisiting the Evidence

Smith’s job is a civilian role. The major crime review team is a small group set up to look at cold cases – homicides, rapes, disappearances – and also review active investigations with fresh eyes. The original team was tasked with collecting all the old case files from around the area and relocating them to a new central archive.

“The case documents 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 containers, their contents now properly secured, returned to storage. Towards the end of 2023, a new lead detective 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 challenging – 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 give it a go?”

The Key Discovery

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

Ryland Headley was 92, 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 pored over every single one of the thousands original statements 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. 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. “She 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, separated 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 amiss.”

Most of the team’s days were spent reading and summarising. (“Humongous amounts of paperwork. It wouldn’t make great TV.”) The team also interviewed the doctor, now 89, 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 stays with you.’”

A History of Violence

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 elderly 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 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 psychiatrist who stated that Headley was not behaving normally. “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 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 identified and approached 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 mid-20th century, how many elderly ladies 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 unique case. “It just feels different, I don’t know why,” she says. “In a live case, 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 box – and I was able to see it through right until the conclusion.”

She is certain that it won’t be the last solved case. There are approximately 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 sending things to forensics and pursuing other lines of inquiry. We’ll be forever unlocking the past.”
