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

In June 2023, Jo Smith, received a request by her supervisor to “take a look at” a cold case from 1967. Louisa Dunne was a elderly woman who had been sexually assaulted and killed in her Bristol home in June 1967. She was a parent of two children, a grandmother, a woman whose first husband had been a prominent labor activist, and whose home had once been a focal point of civic engagement. By 1967, she was residing by herself, twice widowed but still a well-known presence in her local neighbourhood.

There were no one who saw anything to her murder, and the police investigation discovered few leads apart from a handprint on a back window. Officers canvassed eight thousand doors and took 19,000 palm prints, but no identification 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 storage facility to look at the exhibits boxes,” states Smith.

She found three. “I opened the first and closed it again immediately. Most of our cold cases are in sterile evidence bags with identification codes. These were not. They just had old paper tags saying 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, 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 doubt as to the value of submitting something that aged to forensics. It wasn’t seen as a priority.”

It sounds like the beginning of a crime novel, or the first episode of a investigative series. The end result also seems the material for a story. In June, a nonagenarian, the defendant, was found culpable of Louisa Dunne’s rape and murder and given a sentence to life imprisonment.

An Unprecedented Case

Spanning fifty-eight years, this is believed to be the oldest unsolved investigation solved in the UK, and possibly the globe. Later that year, the investigative team won an award for their work. The whole thing still feels remarkable to her. “It just doesn’t feel real,” she says. “It’s forever giving me chills.”

For Smith, cases like this are proof that she made the right career choice. “My father believed 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 24 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 grueling hours. When she saw a job advert for a cold case investigator, she decided to pursue it. “It looked really interesting, 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 cold cases – murders, sexual assaults, disappearances – and also review active investigations with fresh eyes. The original team was tasked with collecting all the old case files from around the area and moving them to a new secure storage facility.

“The Louisa Dunne files had started in a precinct, then, in the years since 1967, they were transferred several times before finally coming here,” says Smith.

Those boxes, their contents now properly secured, returned to storage. Towards the end of 2023, a new senior investigating officer arrived to head up the team. The new officer took a novel strategy. Once an aerospace engineer, Marchant had made a drastic change on his professional journey.

“Solving problems that are hard to solve – that’s my analytical approach – trying to think in innovative manners,” he says. “When Jo told me about the box, it was an absolute no-brainer. Why wouldn’t we try?”

The Breakthrough

In television shows, 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 precedence.”

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 another message. “They had a match on the genetic registry – and it was someone who was living!”

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 period between the DNA match and Headley’s arrest, the team pored over every single one of the thousands original statements and records.

For a while, it was like navigating two eras. “Just looking at all the photographs, 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 came to understand 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, separated from her family, but she remained social. She had a group 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 spoke with the original GP, now 89, 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 haunts you.’”

A Pattern 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 elderly women, again in their own homes. His victims’ disturbing statements from that previous case gave some insight into the victim’s last moments.

“He menaced 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 appealed, supported by a mental health professional who stated that Headley was not behaving normally. “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 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 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 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 die in prison.

A Profound Effect

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 responsive. With this case you’re driving the inquiry, the pressure 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 confident that it is not the last solved case. There are approximately 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.”
