The Way a Appalling Sexual Assault and Killing Case Was Cracked – 58 Years Later.

In the summer of 2023, an investigator, received a request by her sergeant to review a decades-old murder file. Louisa Dunne was a 75-year-old woman who had been raped and murdered in her Bristol home in the month of June 1967. She was a mother of two, a grandmother, a woman whose previous spouse had been a prominent labor activist, and whose home had once been a focal point of civic engagement. By 1967, she was residing by herself, having lost two husbands but still a familiar presence in her Easton neighbourhood.

There were no one who saw anything to her killing, and the initial inquiry found little to go on apart from a handprint on a back window. Investigators knocked on eight thousand doors and took nineteen thousand palm prints, but no identification was found. The case stayed open.

“Upon realizing 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 the officer.

She found three. “I opened the first and put the lid back on again right away. Most of our cold cases 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 forensic examinations.”

The rest of the day was spent with a colleague (it was his initial day on the job), both wearing protective gloves, securely packaging the items and listing what they had. And then nothing more happened for another eight months. Smith pauses and tries to be diplomatic. “I was very enthusiastic, but it did not generate a great deal of enthusiasm. It’s fair to say there was some scepticism as to the worth of submitting something so old to forensics. It wasn’t seen as a priority.”

It sounds like the opening chapter of a mystery book, or the premiere 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 the victim’s rape and murder and given a sentence to life imprisonment.

An Unprecedented Investigation

Covering 58 years, this is believed to be the longest-running cold case solved in the UK, and perhaps the globe. Later that year, the unit won an award 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 proof that she made the right professional decision. “He thought policing was too dangerous,” 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 assisting them when they were in crisis.” Her previous experience in safeguarding involved grueling hours. When she saw a job advert for a cold case investigator, she decided to apply. “It looked really interesting, it’s more of a regular hours role, so I took the position.”

Examining the Evidence

Smith’s job is a non-uniformed position. The major crime review team is a compact team set up to look at historical crimes – homicides, rapes, 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 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 properly secured, 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 engineer, Marchant had made a drastic change on his professional journey.

“Solving problems that are hard to solve – that’s my engineering mindset – trying to think in innovative manners,” he says. “When Jo told me about the box, it was an obvious decision. Why wouldn’t we give it a go?”

The Breakthrough

In cold case crime dramas, once items are sent off to forensics, the results come back quickly. In real life, the submission process and testing take many months. “The forensic team are interested, they want to do it, but our work is always slightly on the back-burner,” says Smith. “Current investigations 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 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!”

The suspect was 92, a widower, and living in Ipswich. “When we realised how old he was, we didn’t have the time to waste,” says Smith. “It was a full team effort.” 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 navigating two time periods. “Just looking at all the photographs, seeing an the victim’s home in 1967,” says Smith. “The witness statements. The way they portray people. Nowadays, it would typically be different. There are so many generational differences.”

Getting to Know 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 on the doorstep every day. She was widowed twice, estranged 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 amiss.”

Most of the team’s days were spent reading and summarising. (“Vast quantities of paperwork. It wouldn’t make compelling television.”) The team also interviewed the original GP, now eighty-nine, who had been at the crime 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 Crimes

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

“He menaced to strangle 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 psychiatrist who stated that Headley was acting out of character. “It went from a life sentence to a shorter term,” 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 health crisis. “We were uncovering the darkest secret he’d kept hidden for sixty 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 believed 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.

“Rape is massively underreported 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 remain incarcerated. He would spend his life behind bars.

A Profound Effect

For Smith, it has been a special case. “It just feels different, I don’t know why,” she says. “With current investigations, the process is very responsive. With this case you’re proactive, the pressure is only from yourself. It started with me trying to get someone to take some notice of that evidence – and I was able to follow it 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 a number of murders that we’re reviewing – we’re constantly submitting evidence to forensics and following other leads. We’ll be forever opening boxes.”
