Revolutionary New Software to bolster efforts in solving Missing Person Cases

NEW investigative software has been unveiled which could support hundreds of thousands of families across the UK in locating their missing loved ones.

In the UK someone is reported missing every 90 seconds, with almost 170,000 people reported missing every year.

The revolutionary software, Quest, was developed by Nottingham-based business Altia and Locate International with a view to helping authorities and families make headway in solving current and long-standing missing persons cases.

With police forces across the country finding their resources stretched, Quest could be a crucial tool in helping them to gather as much information as possible about those missing.

Launched in July 2023 at the Conference of Missing Children and Adults, Quest is an online analytical and investigative tool.

Powered by Altia’s case management software, Insight, Quest collates and links information from family, friends and associates of the missing using a smart, fully searchable platform powered by Altia.

The software enables seamless sharing of critical information from any member of the public regarding a missing person, empowering users to collect all investigation-related data in one place.

Locate also uses Insight’s linking capabilities to combine information from other cases to help them better understand why people go missing and what happens to them, with a view to providing a more effective service in the future.

Altia, which creates intelligence and investigative software, partnered with Locate International, which supports families of unsolved missing person cases, to make it easier for people to gather information about their loved ones in the privacy and safety of their own homes.

As well as collecting information, the software allows police, families, and third parties to quickly obtain comprehensive data which can be analysed as part of an investigation, enhancing collaborative efforts in locating the missing persons.

Finding Marcus Rigby

Quest was recently featured on Channel 5’s ‘Vanished’, a programme dedicated to solving long-standing missing person cases.

The episode followed the case of Marcus Rigby, who was last seen on Portland in 1995 before he went missing on April 27 when he was 27 years.

He first left his hometown of Grange-over-Sands near Cartmel in Cumbria after telling his family he was venturing south to make a ‘fresh start’.

However, the family have not heard from him since this, with his last known sighting being at a bed and breakfast on Artists Row on Portland.

As the search for Marcus continues some 28 years later, Marcus’ family have turned to Quest in the hope it will generate new leads into his disappearance.

Rob Sinclair, CEO, Altia, said: “Across the UK there are tens of thousands of families who are having to deal with the trauma of not knowing what has become of their loved ones.

“One of the cruellest parts of these cases is that there is no closure for those involved, who are left wondering what has happened. That’s exactly the problem we are looking to solve through this collaboration with Locate International.

“The sharing of information is vital to the success of solving any missing person case, and what Quest does is provide a platform which will allow users to not only open the potential to receive a huge amount of data, but also collate it in an efficient way which may help generate new leads for cases which have otherwise gone cold.”

Dave Grimstead, Locate International CEO, said, “When we talk to families of people who are missing, they often tell us that their loved one’s cases haven’t fully been explored. They mention that they have not been asked the ‘right’ questions, or that not everything that could be done, is being done.

“When we talk to police investigators, they tell us that they are stretched and wish they had the resources to do more. With Quest, we set out to tackle these problems.”

Huw Bristow, Altia Chief Technology Officer, said: “We worked with Locate International to configure Insight to follow the process they wanted to use to carry out their investigations.

“Importantly, Insight is browser-based and easy to use so anyone who might have information can use it to add information to a case.

“It’s really important that families find it easy to use, at any time, in the privacy of their own homes – it’s the best possible chance of getting the full picture of the missing person and finding new lines of investigation.”

Altia has been a world leader in developing specialist investigative software for almost 30 years, providing tried, tested and trusted investigation software to a range of stakeholders, from law enforcement agencies to government departments, and private sector businesses.

Powered by Altia, Quest was designed by Locate International and forensic psychologists at Goldsmith’s University
