The poignant stories of those lost to time echo through the halls of justice, waiting to be heard. After more than three decades in the police force, Dave Grimstead is on a mission to uncover the truth behind some of the UK’s most haunting cold cases. With his non-profit organisation, Locate International, he is rallying a dedicated team of volunteers to shed light on the unresolved mysteries that continue to affect families long after the headlines fade.
A Detective’s Dedication
For many detectives, the weight of unsolved cases lingers long after they leave the force. Grimstead, a retired police officer, knows this burden all too well. He recalls the case of Melanie Hall, who vanished from a Bath nightclub in 1996, plunging her family into years of uncertainty. Despite extensive investigations, Hall’s fate remained unknown until her body was discovered in 2009, but the questions surrounding her death remain unanswered.
“Investigations move quickly, but for families, time stands still,” Grimstead reflects. “They may receive sporadic updates, but often, years pass with little hope of closure.” This reality ignited a spark in Grimstead, leading him to envision a new approach to solving these heart-wrenching cases.
The Birth of Locate International
Inspired during a holiday in Cornwall, Grimstead founded Locate International in 2019, drawing parallels to the Royal National Lifeboat Institution (RNLI). Just as the RNLI responds to those lost at sea, Grimstead’s initiative aims to assist families of individuals missing on land. Volunteers, ranging from lawyers to former detectives, are trained to tackle cases of long-term missing persons and unidentified bodies, which often fall through the cracks of police resources.

With a recent surge in interest, Locate International’s latest recruitment drive attracted 200 new volunteers eager to help. “Every case represents a life, a family waiting for answers,” Grimstead asserts. “And with the right support and resources, we can make a difference.”
The Stories that Demand Attention
Grimstead’s book, *Someone Must Know*, highlights several poignant cases that his team is working to resolve. One such story is that of Karen Milsom, a care worker who disappeared in France in 2019. Another is the enigma of the “Sligo Man,” found dead in Ireland in 2009, his identity still unknown. Each case is steeped in tragedy, yet the dedication of Locate International’s volunteers brings hope to families desperate for answers.
“Many of these individuals have tried to erase their identities, but we believe that someone, somewhere, cares,” Grimstead explains. “Our work aims to restore dignity to their stories and provide closure to their loved ones.”
The Challenge of Cold Cases
The statistics surrounding missing persons are staggering. While local police forces handle a multitude of reports daily, approximately 10,000 individuals have been missing for over a year. Grimstead highlights the stark contrast in prioritisation; cases involving immediate danger often overshadow those that linger unresolved. “There’s a pressing need for a shift in how we approach these investigations,” he urges.
Grimstead is also concerned about the impact of the current true crime culture, where sensationalism can sometimes overshadow the real-life trauma experienced by families. He advocates for responsible engagement with these stories, emphasising the importance of compassion and accuracy. “Our volunteers work closely with families and law enforcement, ensuring that our methods respect the dignity of those involved,” he says.
A Glimmer of Hope
Grimstead’s work with Locate International has rekindled the enthusiasm he felt as a young cadet. “In the past, I often saw the worst of humanity,” he admits. “But now, I witness the power of community and the kindness of strangers coming together to help those in need.” The organisation’s success stories, including the recovery of identities for previously unknown individuals, showcase the potential for change within the system.
One notable case involved Vincent Akpiroroh, a man found dead in London in 1994 with only a scrap of paper bearing a misrecorded name. Through diligent research, Grimstead’s team was able to connect with Akpiroroh’s family and uncover the tragic circumstances of his life. “We restored his name and dignity, proving that every individual matters,” he reflects.
Why it Matters
The work of Locate International serves as a poignant reminder of the complexities surrounding cold cases and the importance of community involvement. By unearthing the stories behind the statistics, Grimstead and his volunteers are not only striving to provide answers but also restoring humanity to those whose lives have been overshadowed by tragedy. In a world where time often erases memories, their commitment to seeking the truth is a testament to the power of compassion and resilience. Each case they tackle is not just a mystery; it is a life, a family, and a story waiting to be told.
