How a Shocking Rape and Murder Case Was Cracked – Fifty-Eight Decades Later.

In the summer of 2023, an investigator, received a request by her sergeant to “take a look at” the Louisa Dunne case. The woman 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 prominent labor activist, and whose home had once been a hub of civic engagement. By 1967, she was residing by herself, having lost two husbands but still a familiar figure in her local 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 back window. Investigators knocked on eight thousand doors and took 19,000 palm prints, but no identification was found. The case stayed unsolved.

“When I saw 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 exhibits boxes,” says Smith.

She found three. “I opened the first and put the lid back on again right away. Most of our cold cases are in forensically sealed bags with identification codes. These were not. They just had old paper tags saying what they were. It meant they’d never been subject to 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, forensically bagging the items and cataloging what they had. And then nothing more happened 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. Let’s just say there was some doubt as to the worth of submitting something so old to forensics. It was not considered a priority.”

It sounds like the opening chapter of a crime novel, or the first episode of a investigative series. The end result also seems the stuff of fiction. In the following June, a nonagenarian, the defendant, was found guilty of Louisa Dunne’s rape and murder and sentenced to life.

A Record-Breaking Case

Covering 58 years, this is believed to be the longest-running unsolved investigation closed in the UK, and possibly the globe. Later that year, the unit won an award for their work. The whole thing still feels extraordinary to her. “It just doesn’t feel tangible,” she says. “It’s forever giving me chills.”

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 58-year-old murder?”

Smith joined 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 distress.” Her previous role in child protection involved grueling hours. When she saw a job advert for a crime review officer, she decided to apply. “It looked really interesting, it’s more of a standard schedule role, so I took the position.”

Revisiting the Evidence

Smith’s job is a non-uniformed position. The specialist unit is a compact team set up to look at historical crimes – murders, sexual assaults, long-term missing people – and also review active investigations with fresh eyes. The original team was tasked with gathering all the old case files from around the region 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 were transferred several times before finally coming here,” 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. The new officer took a different approach. 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 new ways,” he says. “When Jo told me about the box, it was an absolute no-brainer. Why wouldn’t we try?”

The Key Discovery

In cold case crime dramas, once items are sent off to forensics, the results come back in days. In real life, the testing procedure and testing take a long time. “The laboratory scientists are interested, 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 message that forensics had a complete genetic fingerprint of the rapist 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 living!”

The suspect was ninety-two, 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 period between the DNA match and Headley’s arrest, the team read 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 old lady’s house in 1967,” says Smith. “The witness statements. The way they portray people. Nowadays, it would typically be different. There are so many generational differences.”

Understanding 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 on the doorstep every day. She was twice widowed, 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 reading and summarising. (“Vast quantities of paperwork. It wouldn’t make great TV.”) The team also spoke with the doctor, now eighty-nine, who had attended the scene. “He remembered every particular 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 the late 1970s he had pleaded guilty to raping 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 resisted. Though Headley was initially sentenced to life, he challenged the verdict, supported by a psychiatrist who stated that Headley was acting out of character. “It went from a life sentence to less time,” 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 were concerned that the arrest would trigger a medical incident. “We were uncovering the darkest secret he’d kept hidden for 60 years,” says Smith.

Yet everything was able to go ahead. The trial took place, and the victim’s living relative had been contacted by specialist officers. “Mary had assumed 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 massively underreported 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 practical purposes, he would remain incarcerated. He would spend his life behind bars.

A Lasting Impact

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 driving the inquiry, 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 follow it right until the end.”

She is confident that it is not the last solved case. There are approximately 130 unsolved investigations 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 submitting evidence to forensics and following other lines of inquiry. We’ll be forever opening boxes.”
