How a Disturbing Sexual Assault and Killing Investigation Was Solved – 58 Years Later.

In June 2023, an investigator, was asked by her sergeant to review the Louisa Dunne case. Louisa Dunne was a elderly woman who had been sexually assaulted and killed in her Bristol home in June 1967. She was a mother, a grandparent, a woman whose first husband had been a prominent labor activist, and whose home had once been a center of civic engagement. By 1967, she was living alone, having lost two husbands but still a well-known presence in her local neighbourhood.

There were no witnesses to her killing, and the police investigation unearthed few leads apart from a palm print on a back window. Officers canvassed 8,000 doors and took 19,000 palm prints, but no identification was found. The case remained unsolved.

“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 exhibits boxes,” states Smith.

She found three. “I opened the first and closed it again right away. Most of our unsolved investigations are in sterile evidence bags with identification codes. These were not. They just had brown cardboard luggage labels indicating what they were. It meant they’d never been subject to 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 listing what they had. And then nothing more happened for another nearly a year. Smith hesitates and tries to be tactful. “I was very enthusiastic, but it wasn’t met with a great deal of enthusiasm. Let’s just say there was some scepticism as to the worth of submitting something so old to forensics. It was not considered 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 June, a 92-year-old man, the defendant, was found culpable of the victim’s rape and murder and sentenced to life.

A Record-Breaking Case

Covering 58 years, this is believed to be the oldest cold case solved in the UK, and possibly the world. Later that year, the investigative team won an award for their work. The whole thing still feels extraordinary 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 career choice. “My father believed policing was too dangerous,” she says, “but what could be better than solving a decades-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 distress.” Her previous role in safeguarding involved grueling hours. When she saw a vacancy for a cold case investigator, she decided to apply. “It looked really interesting, it’s more of a standard schedule role, so here I am.”

Examining the Clues

Smith’s job is a civilian role. The specialist unit is a compact team set up to look at historical crimes – murders, sexual assaults, long-term missing people – and also review live cases 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 central archive.

“The case documents had started in a precinct, then, in the years since 1967, they moved to multiple locations before finally arriving at the archive,” says Smith.

Those containers, their contents now forensically bagged, 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 engineer, Marchant had “taken a hard left” on his career path.

“Cracking cases that are hard to solve – that’s my analytical approach – 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 real life, the testing procedure and testing take a long time. “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 priority.”

It was the end of August 2024 when Smith received a message that forensics had a full DNA profile of the assailant 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 still alive!”

Ryland Headley was 92, widowed, 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 numerous 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 portray people. Nowadays, it would usually 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 outside her home every day. She was twice widowed, 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 analyzing documents. (“Vast quantities of paperwork. It wouldn’t make great TV.”) The team also interviewed the doctor, now 89, who had attended the 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 haunts you.’”

A Pattern of Violence

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 elderly women, again in their own homes. His victims’ disturbing statements from that previous case gave some idea into the victim’s last moments.

“He menaced to choke one and he threatened to smother 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 acting out of character. “It went from a life sentence to a shorter term,” says Smith.

Securing Justice

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 were concerned that the arrest would trigger a health crisis. “We were uncovering the most hidden truth he’d kept hidden for sixty years,” says Smith.

Yet everything was able to go ahead. The court case took place, and the victim’s granddaughter had been contacted by specialist officers. “Mary had assumed it was never going to be solved,” says Smith. For the family, there had also been a stigma about the nature of the crime.

“Sexual assault is massively underreported now,” says Smith, “but in the mid-20th century, how many elderly ladies would ever report this had happened?”

Headley was told at sentencing that, for all practical purposes, he would never be released. 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. “In a live case, the process is very responsive. With this case you’re proactive, the urgency is only from yourself. It began with me trying to get someone to take some interest of that evidence – and I was able to follow it right until the conclusion.”

She is confident that it is not the last resolution. There are approximately 130 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 leads. We’ll be forever unlocking the past.”
