How a Appalling Sexual Assault and Killing Case Was Cracked – Fifty-Eight Decades Later.

In the summer of 2023, a major crime review officer, was tasked by her team leader to “take a look at” a cold case from 1967. Louisa Dunne was a elderly woman who had been raped and murdered in her Bristol home in the month of June 1967. She was a mother, a grandparent, a woman whose previous spouse had been a leading trade unionist, and whose home had once been a focal point of political activity. By 1967, she was living alone, twice widowed but still a recognized figure in her Easton neighbourhood.

There were no one who saw anything to her killing, and the police investigation found little to go on apart from a palm print on a back window. Police knocked on 8,000 doors and took nineteen thousand palm prints, but no identification was found. The case remained 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 storage facility to look at the evidence containers,” says Smith.

She found three. “I opened the first and closed it again immediately. Most of our cold cases are in forensically sealed bags with barcodes. These were not. They just had brown cardboard luggage labels indicating what they were. It meant they’d never been subject to modern forensic examinations.”

The rest of the day was spent with a colleague (it was his initial day on the job), both gloved up, forensically bagging the items and listing what they had. And then there was no progress for another eight months. Smith hesitates and tries to be tactful. “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 worth of submitting something that aged to forensics. It was not considered a high-priority matter.”

It sounds like the beginning of a crime novel, or the premiere of a cold case TV drama. The final outcome also seems the stuff of fiction. In June, a nonagenarian, the defendant, was found culpable of Louisa Dunne’s rape and murder and sentenced to life imprisonment.

A Record-Breaking Investigation

Covering 58 years, this is believed to be the longest-running unsolved investigation solved in the United Kingdom, and perhaps 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 goose bumps.”

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 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 role in child protection involved grueling hours. When she saw a vacancy for a cold case investigator, she decided to apply. “It looked really engaging, it’s more of a standard schedule role, so I took the position.”

Revisiting the Clues

Smith’s job is a civilian role. The specialist unit is a small group set up to look at historical crimes – murders, sexual assaults, long-term missing people – and also re-examine active investigations with a new perspective. 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 were transferred 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. DI Dave Marchant took a different approach. Once an aerospace engineer, Marchant had made a drastic change 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 evidence, it was an absolute no-brainer. Why wouldn’t we give it a go?”

The Breakthrough

In television shows, once items are sent off to forensics, the results come back quickly. In actuality, the submission process and testing take a long time. “The forensic team 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 clothing. A few hours later, she got another message. “They had a hit on the genetic registry – and it was someone who was living!”

The suspect was ninety-two, 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 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 accounts. The way they portray people. Nowadays, it would typically be different. There are so many changes over time.”

Understanding the Victim

Smith felt she got to know 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 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. (“Humongous amounts of paperwork. It wouldn’t make compelling television.”) The team also spoke with the original GP, now eighty-nine, who had attended the 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 haunts you.’”

A History of Violence

Headley’s previous convictions 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 earlier trial gave some insight 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 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.

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

Yet everything was able to go ahead. The trial took place, and the victim’s living relative had been identified and approached 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.

“Rape is massively underreported now,” says Smith, “but in the mid-20th century, how many older women would ever report 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 Lasting Impact

For Smith, it has been a unique case. “It just feels distinct, I don’t know why,” she says. “With current investigations, the process is very responsive. With this case you’re proactive, the urgency is only from yourself. It started 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 approximately one hundred and thirty 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 sending things to forensics and pursuing other leads. We’ll be forever unlocking the past.”
