In the past, missing person investigations relied on door knocks, radio calls, and hours of manual searches. Today, modern technology, social media, and artificial intelligence have given police a much wider range of tools.
With more information at their fingertips, police officers are better equipped than ever to find missing people quickly and bring them home safely.
independent person We spoke to Assistant Constable Damian Miller, head of missing persons at the National Police Chiefs’ Council (NPCC), about how advances in technology are changing investigations.
“Advances in technology are improving the ability of police to locate vulnerable missing persons more quickly, and future advances are expected to reduce the number of missing persons who go undetected,” he said.
In parallel with the charity organization “Missing People”, independent person aims to raise £165,000 to launch SafeCall, a free new service to help the 70,000 children reported missing each year find support and safety no matter what.

search and rescue
Police use data-driven analysis to map the behavior of missing people to help predict how far they may travel and where they are most likely to be found. Automatic number plate recognition systems and vehicle tracking devices can also help police if a missing person is believed to be in a vehicle.
Mr Miller said the use of drones has revolutionized search operations, allowing police to investigate large areas or inaccessible areas at a much lower cost than sending in helicopters. The military can now conduct multiple air searches at once, speeding up the process and sending search parties into areas where conditions may be unsafe for helicopters.
Sonar technology and specialized underwater equipment have also become essential for police, who can locate missing people and related objects such as clothing in rivers and lakes.
digital device
Cell phones have become one of the most powerful tools in missing person investigations. AI systems can analyze vast amounts of mobile site data to pinpoint a person’s location, while social media and push notifications allow police to alert the public within minutes.
Amy Walker, Head of Digital Campaigns at Missing People, said social media has enabled police forces and charities to reach wider audiences.
Mr Miller said: “Virtually everyone leaves a footprint, especially in the digital world. Smartphones, messaging apps and live video apps all provide opportunities to contact missing people, offer assistance and uncover their whereabouts.”
Open source intelligence (scanning public posts and online data) has become an important part of modern search. Police also use Missing People’s TextSafe service. The service sends direct messages to missing people and provides confidential helpline support for those who are not yet ready to approach the police.
artificial intelligence
Artificial intelligence (AI) will continue to be a powerful tool in missing person searches. Police are using facial recognition to scan surveillance camera footage that would normally take hours to review.
“Even if there are no known sightings, high-speed video analytics technology allows us to review hours of surveillance camera footage in minutes, using facial recognition to find possible matches to the missing person and object recognition to find possible matches to distinctive clothing worn by the missing person,” Miller said.
“Analysis of the data has allowed us to develop models that predict where missing people are most likely to be found, how long they have been missing, and how far they have traveled. Artificial intelligence can be used to trace the route a missing person has taken since they were last seen.”
Police are also leveraging AI to quickly analyze large amounts of data to identify risk factors, indicators of exploitation, vulnerable missing persons networks, and potential exploiters.
Dr Varna de Silva, AI expert at Loughborough University, said: “The ability to detect patterns in sensor data streams through machine learning will revolutionize such detection capabilities.
“One of the emerging technologies that could become widespread due to advances in AI is the ability to detect, identify, and track individuals through their radio signal footprints. This technology is known as WiFi radar, and it will allow humans to be detected even where cameras are not present.”
DNA database
Advances in DNA technology will help the UK’s missing persons unit match unidentified bodies with missing person records in the UK and abroad.
Using the UK’s Vulnerable People DNA database, DNA samples can be provided to police to aid future investigations if a person suspected of abuse subsequently goes missing unexpectedly.
“Advances in DNA technology have made it possible to match unidentified bodies and body parts to missing person reports,” Miller said. “With international cooperation, DNA profiles can easily be shared with police in other countries where there is concern that the missing person may have traveled overseas.”
