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

In June 2023, an investigator, was asked by her team leader to “take a look at” a cold case from 1967. Louisa Dunne was a 75-year-old woman who had been raped and murdered in her home city home in the month of June 1967. She was a mother of two, a grandparent, a woman whose first husband had been a leading trade unionist, and whose home had once been a hub of political activity. 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 murder, and the police investigation unearthed little to go on apart from a palm print on a rear window. Officers knocked on eight thousand doors and took 19,000 palm prints, but no match was found. The case remained open.

“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,” says the officer.

She found a trio. “I opened the first and closed it again right away. Most of our unsolved investigations are in sterile evidence 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 wearing protective gloves, securely packaging the items and cataloging what they had. And then nothing more happened for another nearly a year. Smith hesitates and tries to be diplomatic. “I was very enthusiastic, 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 that aged to forensics. It wasn’t seen as a priority.”

It resembles the beginning of a crime novel, or the premiere of a investigative series. The end result also seems the stuff of fiction. In June, a nonagenarian, the defendant, was found guilty of the victim’s rape and murder and sentenced to life.

A Record-Breaking Investigation

Spanning fifty-eight years, this is believed to be the longest-running unsolved investigation closed in the United Kingdom, 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 goose bumps.”

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

Smith entered the police when she was in her twenties 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 grueling hours. When she saw a job advert for a cold case investigator, she decided to apply. “It looked really engaging, it’s more of a standard schedule role, so here I am.”

Examining the Evidence

Smith’s job is a civilian role. The specialist unit is a small group set up to look at historical crimes – murders, sexual assaults, long-term missing people – 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 relocating them to a new secure storage facility.

“The Louisa Dunne files had started in a local police station, then, in the years since 1967, they moved several times before finally arriving at the archive,” says Smith.

Those containers, their contents now forensically bagged, returned to storage. Towards the end of 2023, a new senior investigating officer arrived to lead the team. DI Dave Marchant took a novel strategy. Once an aerospace engineer, Marchant had “taken a hard left” on his career path.

“Solving problems that are hard to solve – that’s my analytical approach – trying to think in new ways,” he says. “When Jo told me about the box, 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 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 lower priority,” 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 clothing. A few hours later, she got another message. “They had a hit on the genetic registry – 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 all hands on deck.” In the weeks between the DNA match and Headley’s arrest, the team read every single one of the thousands original accounts and records.

For a while, it was like living in 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 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 widowed twice, estranged from her family, but she wasn’t reclusive. She had a gaggle 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 reading and summarising. (“Vast quantities of paperwork. It wouldn’t make great TV.”) The team also spoke with the original GP, now eighty-nine, who had attended the scene. “He remembered every particular 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 Crimes

Headley’s previous convictions seemed to leave little doubt of his guilt. After the 1967 murder, he had moved, and in 1977 he had admitted to assaulting two older women, again in their own homes. His victims’ disturbing statements from that earlier trial gave some insight into the victim’s last moments.

“He threatened 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 appealed, 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.

Securing Justice

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 health crisis. “We were uncovering the darkest secret he’d kept hidden for 60 years,” says Smith.

Yet everything was able to proceed. The trial took place, and the victim’s granddaughter had been identified and approached 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.

“Rape is often not reported now,” says Smith, “but in the 60s and 70s, how many elderly ladies would ever report this had happened?”

Headley was told at sentencing that, for all practical purposes, he would remain incarcerated. He would die in prison.

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 reactive. With this case you’re proactive, the urgency is only from yourself. It started 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 certain that it won’t be the last solved case. There are about one hundred and thirty cold cases in the archives. “We’ve got so much more to do,” she says. “We have a number of murders that we’re re-examining – we’re constantly sending things to forensics and following other leads. We’ll be forever opening boxes.”
