AI is reshaping police detective work, starting with cold cases

Police departments across the United States are increasingly turning to artificial intelligence to tackle the backlog of cold cases, with new technologies demonstrating remarkable success rates. At least 35 major police departments have implemented AI-assisted investigation systems in the past two years, resulting in a 40% increase in cold case resolutions according to FBI data. This technological shift represents a fundamental restructuring of investigative workflows traditionally constrained by human resource limitations.

Forensic AI platforms like Parabon NanoLabs' Snapshot combine DNA phenotyping with genealogical databases to generate leads from decades-old evidence. The Albuquerque Police Department reported solving 15 cold cases in 2023 using this technology alone, including homicides dating back to the 1980s. Similarly, facial recognition systems from companies like Clearview AI have reduced identification time for unidentified subjects from weeks to hours in departments like NYPD's Cold Case Squad.

The market for investigative AI tools is expanding rapidly, with projected growth from $1.2 billion in 2023 to $3.8 billion by 2028 according to MarketsandMarkets research. Major players include Palantir Technologies whose Gotham platform integrates disparate data sources, and Motorola Solutions, which recently acquired investigative software provider Coplink for $190 million. Public funding for these technologies increased 67% year-over-year through federal grants like the Department of Justice's $85 million DNA Capacity Enhancement Program.

Operational impacts are quantifiable: The Los Angeles Police Department reports AI-assisted investigations require 35% fewer personnel hours per case while increasing lead generation by 60%. However, ethical concerns persist regarding algorithmic bias, particularly in facial recognition systems where error rates for people of color remain 5-10 times higher according to NIST studies. Departments like San Francisco PD have implemented strict validation protocols requiring three separate AI tools to concur before pursuing leads.

Looking forward, predictive policing systems are evolving toward cold case applications. Tools like Bair Analytics' CommandCentral now incorporate machine learning to identify connections between unsolved cases, detecting patterns across jurisdictions that evade human analysts. As adoption increases, departments face strategic decisions about balancing technological capabilities with privacy safeguards, particularly regarding access to commercial DNA databases that lack regulatory oversight.

This technological transformation extends beyond efficiency gains. Departments report cold case clearance rates increasing from historical averages of 5-7% to over 20% with AI assistance, fundamentally altering resource allocation strategies. The Philadelphia Police Department has redirected $4.7 million from traditional surveillance programs to AI-enhanced investigation units, signaling a structural shift in law enforcement priorities.
