How a Shocking Sexual Assault and Killing Investigation Was Solved – Fifty-Eight Decades Later.

In the summer of 2023, a major crime review officer, was tasked by her team leader to review the Louisa Dunne case. The victim was a elderly woman who had been sexually assaulted and killed in her home city home in the month of June 1967. She was a mother, a grandmother, a woman whose previous spouse had been a leading trade unionist, and whose home had once been a hub 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 one who saw anything to her murder, and the initial inquiry unearthed few leads apart from a handprint on a back window. Investigators canvassed 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 storage facility 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 forensically sealed bags with barcodes. These weren’t. They just had brown cardboard luggage labels 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 wearing protective gloves, securely packaging the items and cataloging what they had. And then there was no progress for another nearly a year. Smith pauses and tries to be tactful. “I was quite excited, 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 that aged to forensics. It was not considered a priority.”

It sounds like the beginning of a crime novel, or the first episode of a cold case TV drama. The end result also seems the material for a story. In the following June, a nonagenarian, the defendant, was found guilty of Louisa Dunne’s rape and murder and given a sentence to life.

A Record-Breaking Case

Spanning 58 years, this is believed to be the oldest unsolved investigation solved in the UK, and perhaps the globe. Later that year, the investigative team won recognition 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 right career choice. “My father believed policing was too risky,” she says, “but what could be better than solving a decades-old murder?”

Smith entered the police when she was in her twenties because, she says: “I’m inquisitive and I was fascinated by people, in assisting them when they were in crisis.” Her previous role in safeguarding involved grueling hours. When she saw a vacancy for a crime review officer, she decided to pursue it. “It looked really interesting, it’s more of a regular hours role, so here I am.”

Examining the Evidence

Smith’s job is a non-uniformed position. The major crime review team is a small group set up to look at cold cases – murders, rapes, disappearances – and also re-examine active investigations with fresh eyes. The original team was tasked with gathering all the old case files from around the area and moving them to a new secure storage facility.

“The case documents had started in a local police station, then, in the years since 1967, they moved several times before finally coming here,” says Smith.

Those containers, their contents now properly secured, 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 made a drastic change on his career path.

“Cracking cases that are challenging – that’s my engineering mindset – 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 quickly. In actuality, the submission process and testing take a long time. “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 precedence.”

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 skirt. A few hours later, she got another message. “They had a hit on the DNA database – and it was someone who was still alive!”

The suspect was ninety-two, 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 period between the DNA match and Headley’s arrest, the team read every single one of the thousands original statements and records.

For a while, it was like navigating two eras. “Just looking at all the photos, seeing an the victim’s home in 1967,” says Smith. “The accounts. 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 big character,” she says. “Lots of people were saying that they saw her on the doorstep every day. She was twice widowed, separated 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 amiss.”

Most of the team’s days were spent analyzing documents. (“Vast quantities of paperwork. It wouldn’t make compelling television.”) The team also interviewed the original GP, now 89, who had attended the 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 stays with you.’”

A History of Crimes

Headley’s prior offenses seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in 1977 he had pleaded guilty to raping two older women, again in their own homes. His victims’ harrowing statements from that previous case 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 not behaving normally. “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 darkest secret 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 living relative had been identified and approached by family liaison. “Mary 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 massively underreported now,” says Smith, “but in the mid-20th century, how many elderly ladies would ever report 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 special case. “It just feels different, I don’t know why,” she says. “In a live case, the process is very reactive. With this case you’re proactive, the pressure is only from yourself. It began with me trying to get someone to take some notice of that box – and I was able to see it through right until the conclusion.”

She is certain that it is not the last resolution. There are approximately 130 cold cases in the archives. “We’ve got so much more to do,” she says. “We have several murders that we’re re-examining – we’re constantly sending things to forensics and pursuing other lines of inquiry. We’ll be forever unlocking the past.”
