How a Disturbing Sexual Assault and Killing Investigation Was Cracked – Fifty-Eight Years Later.

In the summer of 2023, a major crime review officer, was tasked by her supervisor to “take a look at” a decades-old murder file. Louisa Dunne was a elderly woman who had been raped and murdered in her home city home in June 1967. She was a parent of two children, a grandmother, a woman whose first husband had been a prominent trade unionist, and whose home had once been a center of political activity. By 1967, she was residing by herself, twice widowed but still a familiar presence in her Easton neighbourhood.

There were no one who saw anything to her killing, and the initial inquiry discovered few leads apart from a palm print on a back window. Police knocked on eight thousand doors and took nineteen thousand palm prints, but no identification was found. The case stayed 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 archive to look at the exhibits boxes,” says the officer.

She found three. “I opened the first and closed it again immediately. Most of our unsolved investigations are in sterile evidence bags with identification codes. These were not. They just had brown cardboard luggage labels 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, 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 quite excited, but it did not generate a huge amount of enthusiasm. Let’s just say there was some scepticism as to the value of submitting something that aged to forensics. It was not considered a priority.”

It resembles the opening chapter of a mystery book, or the premiere of a investigative series. The final outcome also seems the material for a story. In June, a nonagenarian, the defendant, was found guilty of Louisa Dunne’s rape and murder and sentenced to life imprisonment.

An Unprecedented Case

Spanning 58 years, this is believed to be the longest-running unsolved investigation solved in the UK, and perhaps the world. Subsequently, the unit 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 professional decision. “He thought policing was too dangerous,” she says, “but what could be better than solving a 58-year-old murder?”

Smith joined 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 distress.” Her previous role in safeguarding involved grueling hours. When she saw a job advert for a crime review officer, she decided to apply. “It looked really engaging, it’s more of a regular hours role, so I took the position.”

Examining the Evidence

Smith’s job is a civilian role. The specialist unit is a small group set up to look at historical crimes – homicides, sexual assaults, long-term missing people – and also review active investigations with fresh eyes. The original team was tasked with collecting all the old case files from around the region and moving them to a new central archive.

“The case documents had started in a local police station, then, in the years since 1967, they were transferred several times 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 lead detective 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.

“Cracking cases that are challenging – that’s my analytical approach – trying to think in innovative manners,” 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 cold case crime dramas, once items are sent off to forensics, the results come back quickly. In actuality, the testing procedure and testing take many months. “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 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 match on the DNA database – and it was someone who was still alive!”

The suspect was ninety-two, 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 weeks 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 navigating two time periods. “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.”

Understanding 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 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 original GP, now eighty-nine, who had attended the 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 question of his guilt. After the 1967 murder, he had moved, and in 1977 he had pleaded guilty 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 suffocate 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 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 were concerned 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 proceed. The court case took place, and the victim’s living relative had been contacted by family liaison. “She 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.

“Rape is massively underreported now,” says Smith, “but in the 60s and 70s, how many elderly ladies would ever tell anyone this had happened?”

Headley was told at sentencing that, for all intents and purposes, he would never be released. 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 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 box – and I was able to see it through right until the end.”

She is confident that it is not the last solved case. There are approximately 130 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 sending things to forensics and pursuing other leads. We’ll be forever unlocking the past.”
