The Way a Shocking Sexual Assault and Killing Case Was Resolved – 58 Years Later.

In the summer of 2023, a major crime review officer, was asked by her supervisor 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 of two, a grandparent, a woman whose previous spouse had been a leading trade unionist, and whose home had once been a center of civic engagement. 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 few leads apart from a handprint on a back window. Officers canvassed 8,000 doors and took nineteen thousand palm prints, but no identification was found. The case remained unsolved.

“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 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 barcodes. These weren’t. They just had brown cardboard luggage labels saying 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 nothing more happened for another nearly a year. Smith hesitates and tries to be diplomatic. “I was quite excited, 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 high-priority matter.”

It sounds like the opening chapter of a mystery book, or the first episode of a cold case TV drama. The end result also seems the stuff of fiction. In the following June, a nonagenarian, the defendant, was found culpable of Louisa Dunne’s rape and murder and given a sentence to life imprisonment.

An Unprecedented Investigation

Covering fifty-eight years, this is believed to be the oldest unsolved investigation closed in the UK, and possibly the world. Later that year, the unit won recognition for their work. The whole thing still feels extraordinary to her. “It just doesn’t feel real,” she says. “It’s forever giving me chills.”

For Smith, cases like this are confirmation that she made the correct professional decision. “He thought policing was too risky,” she says, “but what could be better than solving a 58-year-old murder?”

Smith entered the police when she was 24 because, she says: “I’m inquisitive and I was interested in people, in assisting them when they were in distress.” Her previous experience in child protection involved demanding hours. When she saw a job advert for a cold case investigator, she decided to pursue it. “It looked really interesting, it’s more of a regular hours role, so here I am.”

Revisiting the Clues

Smith’s job is a non-uniformed position. The specialist unit is a small group set up to look at historical crimes – murders, rapes, long-term missing people – and also review live cases with a new perspective. The original team was tasked with collecting all the old case files from around the region and relocating them to a new central archive.

“The Louisa Dunne files had originated in a precinct, then, in the years since 1967, they were transferred to multiple locations before finally coming here,” 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. DI Dave Marchant took a different approach. Once an aerospace engineer, Marchant had “taken a hard left” on his career path.

“Solving problems 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 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 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 complete genetic fingerprint of the assailant from the victim’s clothing. A few hours later, she got a follow-up. “They had a match on the genetic registry – and it was someone who was living!”

The suspect 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 period between the DNA match and Headley’s arrest, the team read every single one of the numerous original statements and records.

For a while, it was like living in two eras. “Just looking at all the photos, seeing an the victim’s home in 1967,” says Smith. “The witness statements. The way they describe people. Today, it would usually be different. There are so many changes over time.”

Getting to Know the Victim

Smith felt she got to know the victim, too. “She was such a big character,” she says. “Lots of people were saying that they saw her on the doorstep every day. She was twice widowed, estranged from her family, but she remained social. 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 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 particular 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 History of Crimes

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 assaulting two older women, again in their own homes. His victims’ harrowing statements from that previous case gave some idea 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 resisted. Though Headley was initially sentenced to life, he appealed, 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 strong the evidence was,” she says. The team feared that the arrest would trigger a medical incident. “We were uncovering the most hidden truth he’d kept hidden for 60 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 resolved,” says Smith. For the family, there had also been a stigma about the nature of the crime.

“Sexual assault is often not reported 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 never be released. He would spend his life behind bars.

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 pressure 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 end.”

She is confident that it won’t be the last resolution. There are about 130 unsolved investigations 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 following other lines of inquiry. We’ll be forever unlocking the past.”
