The Way a Appalling Sexual Assault and Killing Investigation Was Cracked – Fifty-Eight Years Later.

In June 2023, Jo Smith, was asked by her supervisor to “take a look at” a cold case from 1967. The woman was a elderly woman who had been raped and murdered in her Bristol home in June 1967. She was a mother, a grandparent, a woman whose first husband had been a leading labor activist, and whose home had once been a center of civic engagement. 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 initial inquiry found little to go on apart from a palm print on a rear window. Officers canvassed eight thousand doors and took 19,000 palm prints, but no identification was found. The case stayed unsolved.

“Upon realizing 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 exhibits boxes,” states the officer.

She found a trio. “I opened the first and put the lid back on again right away. Most of our cold cases are in forensically sealed bags with identification codes. These weren’t. They just had old paper tags saying what they were. It meant they’d never been subject to modern scientific testing.”

The rest of the day was spent with a colleague (it was his first day on the job), both wearing protective gloves, forensically bagging the items and cataloging what they had. And then nothing more happened for another eight months. Smith pauses and tries to be diplomatic. “I was quite excited, but it wasn’t met with a great deal of enthusiasm. Let’s just say there was some doubt as to the worth of submitting something that aged to forensics. It wasn’t seen as a high-priority matter.”

It sounds like the opening chapter of a crime novel, or the first episode of a investigative series. The end result also seems the material for a story. In the following June, a 92-year-old man, the defendant, was found culpable of Louisa Dunne’s rape and murder and sentenced to life.

An Unprecedented Investigation

Covering 58 years, this is believed to be the longest-running unsolved investigation closed in the UK, and possibly the world. Later that year, 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 proof that she made the correct career choice. “My father believed policing was too dangerous,” she says, “but what could be better than resolving a 58-year-old murder?”

Smith entered the police when she was 24 because, she says: “I’m nosy and I was interested in people, in assisting them when they were in crisis.” Her previous experience in safeguarding involved demanding hours. When she saw a vacancy for a crime review officer, she decided to pursue it. “It looked really engaging, it’s more of a standard schedule role, so I took the position.”

Examining the Clues

Smith’s job is a civilian role. The major crime review team is a small group set up to look at historical crimes – homicides, rapes, long-term missing people – and also re-examine live cases with fresh eyes. 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 started in a precinct, then, in the years since 1967, they were transferred several times 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 lead the team. The new officer took a different approach. Once an aerospace engineer, Marchant had “taken a hard left” on his professional journey.

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

The Key Discovery

In cold case crime dramas, once items are sent off to forensics, the results come back in days. In actuality, the testing procedure 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. “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 a follow-up. “They had a hit on the DNA database – and it was someone who was still alive!”

The suspect was 92, widowed, and living in Ipswich. “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 read every single one of the thousands original statements and records.

For a while, it was like living in two time periods. “Just looking at all the photographs, 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 came to understand 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, 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. (“Vast quantities of paperwork. It wouldn’t make compelling television.”) The team also interviewed the doctor, now 89, 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 haunts you.’”

A History 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 assaulting two older women, again in their own homes. His victims’ disturbing 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 challenged the verdict, 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 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 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 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 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 Lasting Impact

For Smith, it has been a special case. “It just feels different, 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 notice of that evidence – and I was able to follow it right until the end.”

She is confident that it is not the last resolution. There are approximately one hundred and thirty 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 sending things to forensics and following other lines of inquiry. We’ll be forever unlocking the past.”
