How a Appalling Rape and Murder Investigation Was Cracked – 58 Years Later.

In the summer of 2023, an investigator, was tasked by her supervisor to “take a look at” the Louisa Dunne case. The woman was a elderly woman who had been raped and murdered in her home city home in June 1967. She was a mother of two, a grandmother, a woman whose first husband had been a prominent trade unionist, and whose home had once been a focal point of civic engagement. By 1967, she was residing by herself, having lost two husbands but still a recognized presence in her Easton neighbourhood.

There were no one who saw anything to her killing, and the initial inquiry discovered few leads apart from a handprint on a back window. Officers knocked on 8,000 doors and took nineteen thousand 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 archive to look at the evidence containers,” states the officer.

She found three. “I opened the first and put the lid back on again right away. Most of our cold cases are in sterile evidence bags with identification codes. These were not. They just had old paper tags indicating what they were. It meant they’d never undergone modern forensic examinations.”

The rest of the day was spent with a colleague (it was his first day on the job), both wearing protective gloves, forensically bagging the items and listing what they had. And then there was no progress for another nearly a year. Smith pauses and tries to be diplomatic. “I was quite excited, but it did not generate a huge amount of enthusiasm. Let’s just say there was some doubt as to the value of submitting something so old to forensics. It wasn’t seen as a priority.”

It resembles the opening chapter of a mystery book, or the first episode of a cold case TV drama. The end result also seems the material for a story. In June, a nonagenarian, Ryland Headley, was found culpable of Louisa Dunne’s rape and murder and sentenced to life imprisonment.

A Record-Breaking Investigation

Covering 58 years, this is believed to be the oldest unsolved investigation closed in the UK, and perhaps the globe. Later that year, the unit won recognition for their work. The whole thing still feels remarkable 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 correct professional decision. “My father believed policing was too risky,” she says, “but what could be better than resolving 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 distress.” Her previous experience in child protection involved grueling hours. When she saw a job advert for a cold case investigator, she decided to pursue it. “It looked really interesting, it’s more of a standard schedule role, so I took the position.”

Revisiting the Clues

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, sexual assaults, long-term missing people – and also re-examine active investigations with fresh eyes. The original team was tasked with collecting all the old case files from around the region and moving them to a new central archive.

“The case documents had originated in a local police station, then, in the years since 1967, they were transferred several times before finally arriving at the archive,” 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. The new officer took a novel strategy. Once an aerospace engineer, Marchant had “taken a hard left” on his professional journey.

“Cracking cases that are hard to solve – that’s my engineering mindset – 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 give it a go?”

The Key Discovery

In television shows, once items are sent off to forensics, the results come back in days. In real life, the testing procedure and testing take many months. “The forensic team are keen, they want to do it, but our work is always slightly on the lower priority,” says Smith. “Live-time murders have to take precedence.”

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

The suspect was ninety-two, a widower, and living in Ipswich. “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 pored over every single one of the thousands original statements and records.

For a while, it was like living in two time periods. “Just looking at all the photos, seeing an old lady’s house in 1967,” says Smith. “The witness statements. The way they describe people. Nowadays, it would typically be different. There are so many generational differences.”

Getting to Know the Victim

Smith felt she got to know 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 twice widowed, estranged 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 very wrong.”

Most of the team’s days were spent analyzing documents. (“Humongous amounts of paperwork. It wouldn’t make great TV.”) The team also interviewed the doctor, now 89, 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 stays with you.’”

A History of Violence

Headley’s prior offenses seemed to leave little question of his guilt. After the 1967 murder, he had moved, and in 1977 he had admitted to assaulting 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 threatened to strangle one and he threatened to smother the other with a pillow,” says Smith. Both women resisted. Though Headley was initially sentenced to life, he appealed, 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 health crisis. “We were uncovering the most hidden truth he’d kept hidden for 60 years,” says Smith.

Yet everything was able to go ahead. The trial took place, and the victim’s granddaughter had been contacted 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 mid-20th century, 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 die in prison.

A Profound Effect

For Smith, it has been a unique case. “It just feels distinct, I don’t know why,” she says. “In a live case, the process is very responsive. With this case you’re proactive, the pressure is only from yourself. It began with me trying to get someone to take some interest of that evidence – and I was able to see it through right until the conclusion.”

She is confident that it is not the last resolution. There are about 130 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 sending things to forensics and following other lines of inquiry. We’ll be forever opening boxes.”
