The Way a Shocking Rape and Murder Investigation Was Resolved – 58 Decades Later.

In the summer of 2023, an investigator, was asked by her sergeant to examine a decades-old murder file. Louisa Dunne was a elderly woman who had been sexually assaulted and killed in her home city home in June 1967. She was a mother, a grandparent, a woman whose first husband 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 well-known presence in her Easton neighbourhood.

There were no one who saw anything to her killing, and the police investigation unearthed few leads apart from a handprint on a rear window. Officers canvassed 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 scientific analysis, so I went to the storage facility to look at the evidence containers,” states the officer.

She found a trio. “I opened the first and put the lid back on again immediately. Most of our cold cases are in sterile evidence bags with identification codes. These weren’t. They just had brown cardboard luggage labels indicating what they were. It meant they’d never undergone modern scientific testing.”

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 cataloging what they had. And then there was no progress for another nearly a year. Smith pauses and tries to be diplomatic. “I was quite excited, but it did not generate a great deal of enthusiasm. Let’s just say there was some scepticism as to the value of submitting something so old to forensics. It was not considered a high-priority matter.”

It resembles the beginning of a mystery book, or the premiere of a cold case TV drama. The final outcome also seems the stuff of fiction. In June, a 92-year-old man, the defendant, was found culpable of Louisa Dunne’s rape and murder and given a sentence to life imprisonment.

An Unprecedented Case

Covering 58 years, this is believed to be the longest-running unsolved investigation closed in the United Kingdom, and possibly the world. Subsequently, the unit won recognition for their work. The whole thing still feels remarkable to her. “It just doesn’t feel real,” she says. “It’s forever giving me goose bumps.”

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

Smith joined the police when she was in her twenties because, she says: “I’m inquisitive and I was interested in people, in assisting them when they were in crisis.” Her previous role in safeguarding involved demanding hours. When she saw a job advert for a cold case investigator, she decided to pursue it. “It looked really engaging, it’s more of a standard schedule role, so I took the position.”

Revisiting the Clues

Smith’s job is a non-uniformed position. The specialist unit is a compact team set up to look at cold cases – 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 secure storage facility.

“The case documents had originated in a local police station, then, in the years since 1967, they moved 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 novel strategy. Once an engineer, Marchant had “taken a hard left” on his career path.

“Cracking cases that are hard to solve – that’s my analytical approach – 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 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 laboratory scientists are interested, they want to do it, but our work is always slightly on the lower priority,” 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 complete genetic fingerprint of the rapist from the victim’s clothing. A few hours later, she got another message. “They had a hit 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 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 numerous original statements and records.

For a while, it was like living in two time periods. “Just looking at all the photos, seeing an old lady’s house in 1967,” says Smith. “The witness statements. The way they portray people. Nowadays, it would usually be different. There are so many generational differences.”

Getting to Know the Victim

Smith felt she got to know the victim, too. “Louisa 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, separated 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 compelling television.”) The team also spoke with the original GP, now eighty-nine, who had attended the 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 Pattern of Crimes

Headley’s previous convictions seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in the late 1970s he had pleaded guilty to assaulting two elderly women, again in their own homes. His victims’ disturbing statements from that earlier trial 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 fought back. Though Headley was initially sentenced to life, he appealed, supported by a mental health professional who stated that Headley was acting out of character. “It went from a life sentence to less time,” says Smith.

Securing Justice

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 strong the evidence was,” she says. The team feared 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 trial 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 often not reported 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 practical purposes, he would never be released. He would die in prison.

A Lasting Impact

For Smith, it has been a unique case. “It just feels distinct, I don’t know why,” she says. “With current investigations, the process is very reactive. With this case you’re driving the inquiry, the urgency 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 certain 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 a number of murders that we’re reviewing – we’re constantly submitting evidence to forensics and pursuing other lines of inquiry. We’ll be forever unlocking the past.”
