How a Disturbing Rape and Murder Investigation Was Resolved – 58 Decades Later.

In the summer of 2023, Jo Smith, was asked by her supervisor to examine the Louisa Dunne case. Louisa Dunne was a 75-year-old woman who had been sexually assaulted and killed in her home city home in the month of June 1967. She was a parent of two children, a grandparent, a woman whose previous spouse had been a prominent labor activist, and whose home had once been a center of civic engagement. By 1967, she was residing by herself, twice widowed but still a familiar figure in her local neighbourhood.

There were no one who saw anything to her killing, and the initial inquiry discovered few leads apart from a palm print on a rear window. Officers canvassed 8,000 doors and took 19,000 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 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 put the lid back on again immediately. Most of our unsolved investigations are in forensically sealed bags with identification codes. These were not. They just had old paper tags indicating what they were. It meant they’d never undergone modern scientific testing.”

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 listing what they had. And then nothing more happened for another nearly a year. Smith hesitates and tries to be tactful. “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 worth of submitting something so old 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 final outcome also seems the material for a story. In June, a nonagenarian, the defendant, was found culpable of Louisa Dunne’s rape and murder and given a sentence to life imprisonment.

An Unprecedented Investigation

Spanning fifty-eight years, this is believed to be the oldest unsolved investigation closed in the UK, and perhaps the world. Later that year, the unit won an award 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 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 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 crime review officer, she decided to apply. “It looked really interesting, it’s more of a regular hours role, so I took the position.”

Examining 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 a new perspective. 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 Louisa Dunne files had started in a precinct, then, in the years since 1967, they were transferred several times before finally arriving at the archive,” says Smith.

Those boxes, their contents now forensically bagged, returned to storage. Towards the end of 2023, a new lead detective arrived to head up the team. DI Dave Marchant took a novel strategy. Once an engineer, Marchant had “taken a hard left” on his career path.

“Solving problems that are challenging – that’s my analytical approach – 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 give it a go?”

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. “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 clothing. A few hours later, she got another message. “They had a hit on the genetic registry – and it was someone who was living!”

The suspect was 92, widowed, and living in Ipswich. “When we realised how old he was, we didn’t have the luxury of time,” says Smith. “It was a full team effort.” In the weeks 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 eras. “Just looking at all the photos, seeing an old lady’s house in 1967,” says Smith. “The witness statements. The way they describe people. Today, it would usually be different. There are so many generational differences.”

Getting to Know 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 widowed twice, estranged 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 reading and summarising. (“Humongous amounts of paperwork. It wouldn’t make great TV.”) 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: ‘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 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’ disturbing statements from that previous case gave some insight into the victim’s last moments.

“He menaced to strangle one and he threatened to smother the other with a cushion,” says Smith. Both women resisted. Though Headley was initially sentenced to life, he appealed, supported by a mental health professional who stated that Headley was acting out of character. “It went from a life sentence to less time,” says Smith.

Securing Justice

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 feared 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 go ahead. The trial took place, and the victim’s living relative had been contacted by specialist officers. “Mary 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 often not reported 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 intents and 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 distinct, I don’t know why,” she says. “With current investigations, the process is very reactive. With this case you’re driving the inquiry, 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 approximately one hundred and thirty unsolved investigations 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 unlocking the past.”
