How a Shocking Sexual Assault and Killing Investigation Was Cracked – 58 Decades Later.

In June 2023, a major crime review officer, received a request by her team leader to “take a look at” a cold case from 1967. Louisa Dunne 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, a grandmother, a woman whose previous spouse had been a leading labor activist, and whose home had once been a center of civic engagement. By 1967, she was residing by herself, having lost two husbands but still a familiar presence in her local neighbourhood.

There were no one who saw anything to her murder, and the police investigation unearthed few leads apart from a palm print on a back window. Officers canvassed eight thousand doors and took 19,000 palm prints, but no identification was found. The case remained open.

“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 exhibits boxes,” says Smith.

She found three. “I opened the first and put the lid back on again immediately. Most of our unsolved investigations are in forensically sealed bags with identification codes. These weren’t. They just had old paper tags saying 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 first day on the job), both gloved up, 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 very enthusiastic, but it wasn’t met with a great deal of enthusiasm. It’s fair to say there was some doubt as to the value of submitting something that aged to forensics. It wasn’t seen as a high-priority matter.”

It resembles the beginning of a crime novel, or the premiere of a investigative series. The end result also seems the material for a story. In the following June, a nonagenarian, Ryland Headley, was found culpable of Louisa Dunne’s rape and murder and sentenced to life imprisonment.

A Record-Breaking Case

Covering fifty-eight years, this is believed to be the longest-running unsolved investigation closed in the UK, and possibly the world. Subsequently, the unit 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 chills.”

For Smith, cases like this are proof that she made the correct career choice. “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 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 role in child protection involved demanding 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 regular hours role, so I took the position.”

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 historical crimes – homicides, sexual assaults, disappearances – and also re-examine live cases 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 Louisa Dunne files 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 head up the team. The new officer took a different approach. Once an aerospace engineer, Marchant had made a drastic change on his professional journey.

“Cracking cases that are challenging – that’s my analytical approach – trying to think in new ways,” he says. “When Jo told me about the evidence, it was an obvious decision. 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 laboratory scientists are keen, 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 notification that forensics had a complete genetic fingerprint of the rapist from the victim’s clothing. A few hours later, she got another message. “They had a hit on the genetic registry – and it was someone who was living!”

Ryland Headley was 92, a widower, 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 pored over 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 the victim’s home in 1967,” says Smith. “The witness statements. The way they describe people. Today, 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 prominent person,” she says. “Lots of people were saying that they saw her on the doorstep every day. She was widowed twice, estranged 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 amiss.”

Most of the team’s days were spent reading and summarising. (“Humongous amounts of paperwork. It wouldn’t make great TV.”) The team also spoke with the original GP, now 89, who had been at the crime scene. “He remembered every detail from that day,” says Smith. “He said: ‘I’ve been a doctor 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 the late 1970s he had admitted to assaulting two older 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 suffocate the other with a pillow,” says Smith. Both women fought back. 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 a shorter term,” says Smith.

Closing the Case

Smith was present at 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 granddaughter had been identified and approached by family liaison. “She had believed it was never going to be resolved,” 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 mid-20th century, how many older women would ever report 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 different, 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 notice of that box – and I was able to see it through right until the conclusion.”

She is confident that it won’t be the last solved case. There are approximately 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 reviewing – we’re constantly sending things to forensics and following other leads. We’ll be forever opening boxes.”
