How a Disturbing Rape and Murder Case Was Cracked – 58 Years After.

In the summer of 2023, an investigator, received a request by her supervisor to review a decades-old murder file. Louisa Dunne was a 75-year-old woman who had been raped and murdered in her home city home in June 1967. She was a parent of two children, a grandparent, a woman whose first husband had been a leading labor activist, and whose home had once been a hub of political activity. By 1967, she was living alone, having lost two husbands but still a familiar presence in her local neighbourhood.

There were no witnesses 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 match was found. The case remained unsolved.

“When I saw that it was dated 1967, I knew we were only going to solve this through scientific analysis, so I went to the archive to look at the exhibits boxes,” states the officer.

She found a trio. “I opened the first and closed it again immediately. 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 forensic examinations.”

The rest of the day was spent with a colleague (it was his initial day on the job), both gloved up, securely packaging the items and cataloging what they had. And then nothing more happened for another eight months. Smith pauses and tries to be tactful. “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 wasn’t seen as a priority.”

It sounds like the opening chapter of a crime novel, or the first episode of a cold case TV drama. The end result also seems the material for a story. In June, a 92-year-old man, the defendant, was found guilty of the victim’s rape and murder and given a sentence to life imprisonment.

A Record-Breaking Case

Spanning 58 years, this is believed to be the longest-running unsolved investigation solved in the United Kingdom, and perhaps the globe. 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 right career choice. “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 24 because, she says: “I’m nosy and I was fascinated by people, in assisting them when they were in crisis.” Her previous experience in child protection involved demanding hours. When she saw a vacancy for a cold case investigator, she decided to apply. “It looked really interesting, it’s more of a standard schedule role, so I took the position.”

Revisiting the Clues

Smith’s job is a civilian role. The major crime review team is a compact team set up to look at historical crimes – homicides, sexual assaults, disappearances – and also review live cases with fresh eyes. The original team was tasked with gathering all the old case files from around the area and moving them to a new central archive.

“The Louisa Dunne files had originated in a local police station, then, in the years since 1967, they were transferred to multiple locations before finally coming here,” says Smith.

Those containers, their contents now properly secured, returned to storage. Towards the end of 2023, a new lead detective arrived to lead 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 hard to solve – that’s my engineering mindset – trying to think in new ways,” he says. “When Jo told me about the box, it was an absolute no-brainer. Why wouldn’t we give it a go?”

The Key Discovery

In television shows, once items are sent off to forensics, the results come back in days. In real life, the submission process and testing take many months. “The forensic team 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 precedence.”

It was the end of August 2024 when Smith received a notification that forensics had a full DNA profile of the rapist from the victim’s skirt. A few hours later, she got a follow-up. “They had a match on the DNA database – 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 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 time periods. “Just looking at all the photos, 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.”

Understanding 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 outside her home every day. She was widowed twice, estranged 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 very wrong.”

Most of the team’s days were spent analyzing documents. (“Vast quantities of paperwork. It wouldn’t make great TV.”) The team also spoke with the doctor, 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 stays with you.’”

A History of Violence

Headley’s prior offenses 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 insight into the victim’s last moments.

“He menaced to strangle one and he threatened to suffocate the other with a pillow,” says Smith. Both women resisted. Though Headley was initially sentenced to life, he appealed, supported by a psychiatrist who stated that Headley was acting out of character. “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 were concerned that the arrest would trigger a medical incident. “We were uncovering the darkest secret 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 identified and approached by specialist officers. “Mary had believed it was never going to be solved,” 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 mid-20th century, 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 reactive. With this case you’re driving the inquiry, 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 end.”

She is certain that it won’t be the last resolution. There are about 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 sending things to forensics and following other lines of inquiry. We’ll be forever opening boxes.”
