A new artificial intelligence tool, Söze, is being trialed by Avon and Somerset Police to assist in solving some of the UK’s most notorious cold cases. Developed in Australia, this Ai aims to drastically reduce the time needed to process vast amounts of data, potentially unlocking leads that may have gone unnoticed.
A New Era in Investigation
Söze’s strength lies in its ability to analyze different types of evidence simultaneously. It can review video footage, financial records, social media activity, emails, and other documents in record time. During one trial, the tool processed evidence from 27 complex investigations in just 30 hours—a task that would have taken human detectives 81 years! Its ability to sift through massive amounts of data makes it especially useful for cold cases where evidence piles up over time.
New Hope for Unsolved Cases
Gavin Stephens, Chair of the National Police Chiefs’ Council, sees the potential of this technology for solving cold cases. Many of these cases feel unmanageable due to the sheer volume of material that needs to be reviewed. Söze, however, can process and assess the data far more quickly. “You might have a cold case review that just looks impossible because of the amount of material,” Stephens explained. “Feed it into a system like this, and it can give you an assessment of it.”
This comes at a time when police resources are stretched thin. Recently, the Metropolitan Police reduced the number of officers assigned to cold case investigations, leaving cases like the 1994 murder of Atek Hussain still unsolved. Söze could be a key tool in keeping investigations like these moving forward.

AI’s Expanding Role in Policing
Söze is one of many AI-based technologies currently being trialed by police forces across the UK. Other innovations include a national knife database for monitoring sales and tracking weapons, as well as AI systems that prioritize calls from domestic abuse victims. Stephens pointed out that if all of these AI-driven tools were implemented across the UK, they could save millions of hours in police work, equating to significant cost savings.
Still, Stephens emphasized that AI isn’t replacing human officers. These tools are meant to enhance efficiency, leaving officers free to make critical decisions. “This isn’t handing over our responsibilities to technology,” he noted, “but what the technology is helping us to do better.”
Technology Enhancing Human Judgement
As AI continues to develop, its role in law enforcement is likely to expand. Police leaders are cautious, ensuring the adoption of these tools aligns with public trust and ethical guidelines. While facial recognition and other AI-driven systems will reshape policing, humans will always play a crucial role in the final decision-making process.
The goal is not to replace the human element but to enhance it, speeding up investigations and improving accuracy. With Söze and other AI tools, there’s hope that long-forgotten cold cases may finally see closure.
