How a Shocking Sexual Assault and Killing Case Was Solved – 58 Years Later.

In June 2023, an investigator, received a request by her supervisor to “take a look at” 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 the month of June 1967. She was a mother, a grandmother, a woman whose first husband had been a prominent trade unionist, and whose home had once been a focal point of political activity. By 1967, she was living alone, having lost two husbands but still a recognized presence in her local neighbourhood.

There were no witnesses to her killing, and the police investigation unearthed few leads apart from a handprint on a back window. Police knocked on 8,000 doors and took 19,000 palm prints, but no match was found. The case remained unsolved.

“Upon realizing that it was dated 1967, I knew we were only going to solve this through forensics, so I went to the storage facility to look at the evidence containers,” says the officer.

She found three. “I opened the first and closed it again immediately. Most of our cold cases are in sterile evidence bags with barcodes. These weren’t. They just had brown cardboard luggage labels indicating what they were. It meant they’d never been subject to modern forensic examinations.”

The rest of the day was spent with a co-worker (it was his initial 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 hesitates and tries to be tactful. “I was very enthusiastic, but it wasn’t met with a huge amount of enthusiasm. It’s fair to say there was some scepticism as to the value of submitting something so old to forensics. It wasn’t seen as a high-priority matter.”

It resembles the beginning of a mystery book, or the first episode of a investigative series. The final outcome also seems the material for a story. In the following June, a nonagenarian, Ryland Headley, was found culpable of Louisa Dunne’s rape and murder and sentenced to life.

A Record-Breaking Case

Spanning fifty-eight years, this is believed to be the longest-running unsolved investigation solved in the UK, and possibly the globe. Subsequently, the unit won recognition for their work. The whole thing still feels extraordinary 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 solving a decades-old murder?”

Smith joined the police when she was in her twenties because, she says: “I’m nosy and I was interested in people, in helping them when they were in distress.” Her previous experience in safeguarding involved demanding 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.”

Revisiting the Clues

Smith’s job is a civilian role. The major crime review team is a small group set up to look at historical crimes – murders, sexual assaults, disappearances – and also review active investigations 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 central archive.

“The case documents had originated in a local police station, then, in the years since 1967, they moved to multiple locations before finally arriving at the archive,” says Smith.

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

“Cracking cases 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 give it a go?”

The Key Discovery

In television shows, once items are sent off to forensics, the results come back quickly. In actuality, the submission process and testing take many months. “The forensic team are interested, 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 match on the genetic registry – and it was someone who was living!”

The suspect was 92, a widower, and living in another city. “When we realised how old he was, we didn’t have the time to waste,” says Smith. “It was a full team effort.” In the weeks between the DNA match and Headley’s arrest, the team pored over every single one of the numerous 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.”

Understanding the Victim

Smith felt she came to understand 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, separated 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 reading and summarising. (“Vast quantities of paperwork. It wouldn’t make compelling television.”) 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 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 admitted to raping two elderly women, again in their own homes. His victims’ disturbing statements from that earlier trial gave some idea 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 challenged the verdict, 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 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 feared that the arrest would trigger a medical incident. “We were uncovering the most hidden truth he’d kept hidden for sixty years,” says Smith.

Yet everything was able to proceed. The court case took place, and the victim’s granddaughter had been contacted 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.

“Sexual assault 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 intents and purposes, he would remain incarcerated. He would die in prison.

A Profound Effect

For Smith, it has been a unique case. “It just feels different, 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 follow it right until the end.”

She is confident that it is not the last solved case. There are approximately one hundred and thirty cold cases in the archives. “We’ve got so much more to do,” she says. “We have several murders that we’re reviewing – we’re constantly submitting evidence to forensics and pursuing other leads. We’ll be forever unlocking the past.”
