REDMOND, Wash. — A new artificial intelligence tool is helping local law enforcement solve crimes, and in one case, it helped find a major clue in a cold case.
When a crime happens, police begin compiling a mountain of digital evidence including surveillance video, phone records, crime scene photos and interviews. It can be a lot to sort through, so Redmond Police are now using a new AI tool to help.
“Longeye is an investigative, I call it an investigative support tool,” said Redmond Police Chief Darrell Lowe. “It’s an AI-driven platform where investigators are able to upload digital information. It processes the information and provides, I’ll call it insights, to the investigators or reference points.”
Chief Lowe said the system helped investigators revisit a cold case by analyzing 60 hours of jail phone calls and pinpointing a key confession.
“Investigators had questions around whether there were one or two bullets fired,” Lowe said. “In one of those phone calls, the suspect confessed to firing two shots and hiding the shell casing underneath a deck.”
The AI tool helped detectives process those 60 hours of calls in a matter of minutes, saving what Chief Lowe described as significant time.
“That’s a week and a half of an investigator’s time, and that would be full time,” he said.
The company behind the software, Longeye, says it is designed to speed up investigations, not replace investigators.
“A lot of people picture this as like some black box where like out comes the ‘Steven did it,’” said Guillaume Delépine, Longeye’s co-founder and CEO. “But it’s really not like that. It’s a tool for a good investigator to move faster and be more thorough through these big, heavy data sets.”
Delépine said the software ranks files by how relevant they are to each case, helping officers focus on the key evidence first.
“The truth is, in the data somewhere, right?” Delépine said. “And it just makes better investigations, better trials. It’s good for everyone.”
Chief Lowe said using AI is not just about saving time, it is about giving detectives more time to serve victims and close cases.
“AI will not replace the need for actual officers or investigators,” he said. “But it will enhance their effectiveness.”
Redmond Police emphasize that Longeye does not create or predict information. It only points detectives to evidence they already have, helping them work smarter and faster.
Longeye is not grant-funded. Chief Lowe integrated the use of Longeye within his existing approved budget.
There are also multiple other agencies in Washington state currently considering using Longeye.
