How a Shocking Sexual Assault and Killing Investigation Was Cracked – 58 Years After.

In the summer of 2023, a major crime review officer, received a request by her supervisor to review a cold case from 1967. Louisa Dunne was a 75-year-old 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 political activity. By 1967, she was living alone, having lost two husbands but still a well-known presence in her Easton neighbourhood.

There were no one who saw anything to her killing, and the police investigation found little to go on apart from a handprint on a back window. Police knocked on 8,000 doors and took 19,000 palm prints, but no identification was found. The case stayed 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 exhibits boxes,” states Smith.

She found a trio. “I opened the first and closed it again right away. Most of our cold cases are in forensically sealed bags with identification codes. These weren’t. They just had old paper tags 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 diplomatic. “I was quite excited, but it wasn’t met with a huge amount of enthusiasm. It’s fair to say there was some doubt as to the worth of submitting something so old to forensics. It wasn’t seen as a priority.”

It sounds like the beginning of a mystery book, or the first episode of a cold case TV drama. The final outcome also seems the stuff of fiction. In June, a nonagenarian, the defendant, was found guilty of Louisa Dunne’s rape and murder and given a sentence to life imprisonment.

A Record-Breaking Case

Covering 58 years, this is believed to be the longest-running cold case solved in the UK, and possibly the world. Subsequently, the investigative team won recognition for their work. The whole thing still feels extraordinary to her. “It just doesn’t feel tangible,” she says. “It’s forever giving me goose bumps.”

For Smith, cases like this are confirmation 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 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 experience in safeguarding involved grueling 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.”

Examining the Evidence

Smith’s job is a civilian role. The major crime review team is a small group set up to look at historical crimes – homicides, sexual assaults, long-term missing people – and also review active investigations with a new perspective. The original team was tasked with gathering all the old case files from around the region and relocating them to a new secure storage facility.

“The case documents had originated in a precinct, 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 aerospace engineer, Marchant had made a drastic change on his career path.

“Cracking cases that are challenging – that’s my analytical approach – trying to think in innovative manners,” he says. “When Jo told me about the evidence, 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 submission process and testing take a long time. “The forensic team are interested, they want to do it, but our work is always slightly on the lower priority,” says Smith. “Live-time murders 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 hit on the DNA database – 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 weeks between the DNA match and Headley’s arrest, the team read every single one of the thousands original accounts and records.

For a while, it was like navigating two time periods. “Just looking at all the photos, seeing an old lady’s house in 1967,” says Smith. “The accounts. The way they describe people. Nowadays, it would usually be different. There are so many changes over time.”

Getting to Know the Victim

Smith felt she got to know 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 group 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. (“Humongous amounts of paperwork. It wouldn’t make compelling television.”) The team also spoke with the original GP, 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 Pattern of Violence

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’ harrowing statements from that earlier trial gave some insight into the victim’s last moments.

“He threatened to strangle 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 psychiatrist 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 were concerned 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 living relative had been identified and approached by family liaison. “Mary had believed 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 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 never be released. He would spend his life behind bars.

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 reactive. 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 evidence – and I was able to see it through right until the end.”

She is confident that it won’t be the last resolution. There are about one hundred and thirty cold cases 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 following other lines of inquiry. We’ll be forever opening boxes.”
