ABC7 News covers how Longeye is giving law enforcement a powerful new AI tool to process mountains of digital evidence in seconds, featuring a live demonstration with South San Francisco Police.
ABC7 News reports on how Longeye, a Bay Area AI startup co-founded by Guillaume Delepine, is transforming how law enforcement processes digital evidence. The segment features a live demonstration with South San Francisco Police Captain Anthony Penel, showing how Longeye analyzed 100 jailhouse phone calls from a felony case in seconds, identifying a critical conversation where suspects coordinated an alibi in Spanish.
The story highlights how 70 percent of investigators today do not have enough time to review all of their digital evidence. With surveillance footage, phone calls, texts, emails, and massive PDFs, the volume of potential evidence has exploded while detective staffing has stayed flat. Longeye streamlines this process, connecting dots across thousands of pages and hours of recordings that would take human reviewers days or weeks.
Newly retired San Ramon Police Chief Denton Carlson, who joined the Longeye team, calls the technology game-changing for law enforcement. The segment also highlights a case where a department’s interpreter missed a confession buried in 30 hours of recorded calls that Longeye flagged immediately.
Good old-fashioned police work solves crime. But in an increasingly digital world, shoe leather isn’t always enough. Enter Longeye, a Bay Area AI startup co-founded by Guillaume Delepine, using artificial intelligence to help street-smart cops catch crooks.
Tell me about the concept.
Longeye is based on the fact that 70% of investigators don’t have time to get through all of the digital evidence that they have to go through. There’s just too much potential evidence to examine. On any given case, we’re talking about surveillance camera footage, hours of phone calls, thousands of texts and emails, more evidence than ever. And in most departments, no more detectives than years ago.
When newly retired San Ramon Police Chief Denton Carlson saw the technology, he wanted to be a part of it and joined the Longeye team. The technology, he believes, is game-changing for law enforcement.
You’re one click away and you’re going to the actual evidence to verify exactly what the AI has found for you. Not just searching the random internet. You’re going to the evidence that you have inputted, basically.
Exactly, with clear citations and direct links.
Captain Anthony Penel of South San Francisco Police was part of a real-world Longeye demonstration, using the AI tool to comb through 100 jailhouse phone calls from a suspect in a felony case.
The system was able to point directly to the most relevant call, which ended up being one of our suspects discussing their alibi through a third party to plan an alibi with one of the other suspects.
So what would have taken detectives hours and hours, if not weeks, to sort through, the Longeye AI tool did in just seconds. And what’s more, it found that conversation in Spanish. It can do this in 100 languages.
Longeye co-founder Guillaume Delepine says the sheer amount of electronic evidence today is overwhelming. His creation streamlines the process and connects the dots.
That sometimes are in 30,000-page PDFs, thousands of pages apart, all brought into one bullet point that helps the detective understand what’s going on on the ground.
Giving law enforcement a powerful new tool that changes how police do their jobs and how the bad guys get caught.
You’re making it very difficult for me to pursue the life of crime I’d always imagined.
Here’s another example. One department hired an interpreter to go through 30 hours of recorded phone calls. The interpreter found nothing. When they ran it through the Longeye platform, it immediately flagged a confession from the suspect that the interpreter had missed.
Longeye continues to expand to more than a dozen police departments around California and Arizona, with many more on the horizon.
