How a Shocking Sexual Assault and Killing Case Was Solved – 58 Decades Later.

In the summer of 2023, an investigator, received a request by her sergeant to “take a look at” a decades-old murder file. The woman was a elderly woman who had been raped and murdered in her home city home in June 1967. She was a mother, a grandmother, a woman whose first husband had been a leading trade unionist, and whose home had once been a focal point of civic engagement. By 1967, she was residing by herself, twice widowed but still a well-known presence in her local neighbourhood.

There were no one who saw anything to her murder, and the initial inquiry found few leads apart from a handprint on a rear window. Police canvassed eight thousand doors and took 19,000 palm prints, but no identification 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 storage facility to look at the evidence containers,” says 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 forensically sealed bags with barcodes. These weren’t. They just had brown cardboard luggage labels saying what they were. It meant they’d never undergone modern scientific testing.”

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 cataloging what they had. And then there was no progress for another nearly a year. 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 resembles the beginning of a crime novel, or the premiere of a cold case TV drama. The final outcome also seems the material for a story. In June, a 92-year-old man, the defendant, was found guilty 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 possibly 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 tangible,” she says. “It’s forever giving me chills.”

For Smith, cases like this are confirmation that she made the right professional decision. “He thought policing was too risky,” 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 role in safeguarding involved demanding hours. When she saw a job advert for a crime review officer, she decided to pursue it. “It looked really engaging, 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 specialist unit is a small group set up to look at cold cases – murders, rapes, long-term missing people – and also re-examine 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 originated in a precinct, then, in the years since 1967, they moved 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 senior investigating officer arrived to lead the team. DI Dave Marchant 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 box, it was an obvious decision. 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 testing procedure 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. “Current investigations have to take priority.”

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 a follow-up. “They had a match 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 period between the DNA match and Headley’s arrest, the team pored over every single one of the numerous original statements 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 portray people. Today, it would typically be different. There are so many changes over time.”

Understanding the Victim

Smith felt she came to understand the victim, too. “She was such a big character,” she says. “Lots of people were saying that they saw her outside her home every day. She was twice widowed, separated 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 amiss.”

Most of the team’s days were spent analyzing documents. (“Vast quantities 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 particular 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 Crimes

Headley’s prior offenses seemed to leave little doubt of his guilt. After the 1967 murder, he had moved, and in 1977 he had pleaded guilty to assaulting two older women, again in their own homes. His victims’ harrowing 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 pillow,” says Smith. Both women fought back. 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 a shorter term,” 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 compelling the proof was,” she says. The team feared that the arrest would trigger a health crisis. “We were uncovering the darkest secret he’d kept hidden for sixty years,” says Smith.

Yet everything was able to go ahead. The court case took place, and the victim’s granddaughter had been identified and approached by family liaison. “Mary had assumed it was never going to be resolved,” says Smith. For the family, there had also been a stigma about the nature of the crime.

“Rape 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 intents and purposes, he would remain incarcerated. He would spend his life behind bars.

A Lasting Impact

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 driving the inquiry, the urgency is only from yourself. It started with me trying to get someone to take some interest of that box – and I was able to follow it right until the conclusion.”

She is confident that it won’t be the last solved case. 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 pursuing other leads. We’ll be forever opening boxes.”
