How a Shocking Sexual Assault and Killing Investigation Was Resolved – 58 Years Later.

In June 2023, a major crime review officer, received a request by her supervisor to “take a look at” a decades-old murder file. 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 of two, a grandparent, a woman whose previous spouse had been a leading labor activist, and whose home had once been a focal point of political activity. By 1967, she was living alone, 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 police investigation unearthed little to go on apart from a palm print on a back window. Officers knocked on 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 evidence containers,” says Smith.

She found a trio. “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 weren’t. 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 co-worker (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 nearly a year. Smith hesitates and tries to be tactful. “I was quite excited, but it did not generate a great deal of enthusiasm. It’s fair to say there was some doubt as to the worth of submitting something that aged to forensics. It was not considered a priority.”

It resembles the opening chapter of a mystery book, or the first episode of a investigative series. The final outcome also seems the material for a story. In June, a 92-year-old man, the defendant, was found culpable of Louisa Dunne’s rape and murder and given a sentence to life.

A Record-Breaking Investigation

Spanning fifty-eight years, this is believed to be the longest-running cold case solved in the United Kingdom, and possibly the world. Subsequently, the investigative team won recognition 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 confirmation that she made the right professional decision. “He thought policing was too risky,” she says, “but what could be better than resolving 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 grueling hours. When she saw a vacancy for a crime review officer, she decided to pursue it. “It looked really interesting, it’s more of a standard schedule role, so here I am.”

Examining the Evidence

Smith’s job is a civilian role. The specialist unit is a small group set up to look at historical crimes – murders, rapes, long-term missing people – and also review active investigations with a new perspective. 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 case documents had originated in a local police station, then, in the years since 1967, they moved to multiple locations before finally arriving at the archive,” says Smith.

Those boxes, 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 engineer, Marchant had “taken a hard left” on his professional journey.

“Solving problems that are challenging – that’s my analytical approach – trying to think in new ways,” he says. “When Jo told me about the box, it was an absolute no-brainer. Why wouldn’t we try?”

The Key Discovery

In cold case crime dramas, 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 interested, they want to do it, but our work is always slightly on the lower priority,” says Smith. “Live-time murders have to take priority.”

It was the end of August 2024 when Smith received a notification that forensics had a full DNA profile of the assailant from the victim’s clothing. A few hours later, she got another message. “They had a hit on the genetic registry – and it was someone who was still alive!”

The suspect was 92, a widower, and living in another city. “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 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 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 generational differences.”

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 on the doorstep every day. She was widowed twice, separated from her family, but she wasn’t reclusive. 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 eighty-nine, 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 Pattern of Violence

Headley’s previous convictions seemed to leave little doubt of his guilt. After the 1967 murder, he had moved, and in the late 1970s he had admitted to raping two older women, again in their own homes. His victims’ harrowing statements from that earlier trial gave some insight into the victim’s last moments.

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

Closing the Case

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 medical incident. “We were uncovering the darkest secret he’d kept hidden for 60 years,” says Smith.

Yet everything was able to proceed. The trial took place, and the victim’s living relative had been contacted by specialist officers. “Mary had assumed it was never going to be resolved,” says Smith. For the family, there had also been a sense of shame about the nature of the crime.

“Sexual assault is often not reported now,” says Smith, “but in the 60s and 70s, how many elderly ladies would ever report this had happened?”

Headley was told at sentencing that, for all intents and purposes, he would remain incarcerated. He would spend his life behind bars.

A Profound Effect

For Smith, it has been a unique case. “It just feels distinct, I don’t know why,” she says. “In a live case, the process is very reactive. With this case you’re proactive, the urgency 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 end.”

She is certain that it is not the last solved case. There are about 130 cold cases in the archives. “We’ve got so much more to do,” she says. “We have a number of 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.”
