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

In June 2023, an investigator, was tasked by her team leader to examine a decades-old murder file. Louisa Dunne was a 75-year-old woman who had been sexually assaulted and killed in her home city home in June 1967. She was a parent of two children, a grandmother, a woman whose previous spouse had been a leading trade unionist, and whose home had once been a center of civic engagement. By 1967, she was living alone, twice widowed but still a well-known presence in her local neighbourhood.

There were no one who saw anything to her murder, and the initial inquiry discovered little to go on apart from a palm print on a rear window. Police 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 forensics, so I went to the storage facility to look at the evidence containers,” states Smith.

She found a trio. “I opened the first and put the lid back on again right away. Most of our unsolved investigations 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 co-worker (it was his initial day on the job), both gloved up, securely packaging the items and listing what they had. And then nothing more happened for another eight months. Smith hesitates and tries to be diplomatic. “I was quite excited, but it did not generate a great deal of enthusiasm. It’s fair to say there was some doubt 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 first episode of a cold case TV drama. The final outcome also seems the material for a story. In June, a nonagenarian, the defendant, was found guilty of the victim’s rape and murder and sentenced to life.

An Unprecedented Investigation

Covering 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 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. “My father believed 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 role in child protection involved grueling hours. When she saw a job advert for a crime review officer, she decided to pursue it. “It looked really engaging, it’s more of a regular hours role, so I took the position.”

Examining the Clues

Smith’s job is a non-uniformed position. The major crime review team is a compact team set up to look at cold cases – murders, sexual assaults, disappearances – and also re-examine active investigations with a new perspective. The original team was tasked with gathering all the old case files from around the region and moving them to a new central archive.

“The case documents had originated in a precinct, then, in the years since 1967, they moved several times before finally arriving at the archive,” says Smith.

Those boxes, their contents now forensically bagged, 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 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 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 back-burner,” says Smith. “Current investigations have to take priority.”

It was the end of August 2024 when Smith received a notification that forensics had a complete genetic fingerprint of the assailant from the victim’s clothing. A few hours later, she got a follow-up. “They had a match on the DNA database – and it was someone who was still alive!”

The suspect was 92, widowed, and living in another city. “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 weeks 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 living in two eras. “Just looking at all the photos, seeing an old lady’s house in 1967,” says Smith. “The witness statements. The way they portray people. Today, it would usually be different. There are so many changes over time.”

Getting to Know 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 outside her home every day. She was twice widowed, 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 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 interviewed the doctor, now eighty-nine, who had been at the crime scene. “He remembered every detail from that day,” says Smith. “He said: ‘In my career all my life and seen a lot of dead bodies but that’s the only one that had been murdered. That haunts 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 the late 1970s he had pleaded guilty to assaulting two older women, again in their own homes. His victims’ disturbing statements from that previous case gave some idea into the victim’s last moments.

“He threatened 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 a shorter term,” 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 feared that the arrest would trigger a health crisis. “We were uncovering the most hidden truth 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 granddaughter had been contacted by family liaison. “She had assumed it was never going to be resolved,” says Smith. For the family, there had also been a stigma about the nature of the crime.

“Sexual assault is often not reported now,” says Smith, “but in the 60s and 70s, how many older women would ever tell anyone this had happened?”

Headley was told at sentencing that, for all intents and purposes, he would never be released. He would spend his life behind bars.

A Profound Effect

For Smith, it has been a unique case. “It just feels different, I don’t know why,” she says. “With current investigations, 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 conclusion.”

She is confident that it won’t be the last resolution. There are approximately 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 re-examining – we’re constantly submitting evidence to forensics and pursuing other lines of inquiry. We’ll be forever unlocking the past.”
