CoAnalyst in Action: Real-World Examples of AI-Powered Investigations
Date Posted: June 18th, 2025
How AI is Changing Digital Investigations
Today, law enforcement agencies and investigators face huge amounts of data from many sources—call detail records (CDRs), social media, financial transactions, encrypted messages, and more. Manually sorting through it all can take weeks and delay investigations.
CoAnalyst, Penlink’s AI-powered tool, helps speed up the process. It finds key information and surfaces connections in just seconds.
Here’s what that looks like in practice. Below are three real-world examples of how CoAnalyst has helped investigative teams move cases forward.
Case #1: Uncovering Human Trafficking Networks
The Challenge A multi-agency task force was investigating a suspected human trafficking operation. They had thousands of call records, social media messages, and financial transactions. Manually reviewing it all wasn’t realistic.
Natural language processing (NLP) flagged coded messages and signs of recruitment on social media.
Investigators asked simple questions like: “List all connections between these phone numbers and financial transactions over $500.”
The Outcome
In just a few hours, investigators found the key suspects, tracked their movements, and uncovered a recruitment network that crossed state lines. That led to several arrests and the rescue of victims.
Case #2: Solving a Cold Case Homicide
The Challenge A homicide investigation had stalled because there wasn’t much direct evidence. Investigators had digital forensic data from a suspect’s phone, but there were years of messages, call logs, and emails to go through.
How CoAnalyst Helped
The system quickly went through old digital evidence and highlighted messages related to the crime scene.
NLP picked up on small but important connections in the suspect’s past conversations.
Location data helped confirm the suspect was near the scene when the crime happened.
The Outcome New leads came to light. Detectives were able to strengthen the case and present solid digital evidence in court. The suspect was arrested, and a five-year-old case was finally closed.
Case #3: Disrupting Organized Crime Operations
The Challenge A law enforcement agency was working a drug trafficking case across several jurisdictions. The suspects used encrypted messaging apps, burner phones, and moved money across borders.
How CoAnalyst Helped
Metadata from encrypted messages revealed how the suspects were communicating.
The tool identified frequent phone number changes, helping uncover key members of the group.
Investigators used network diagrams to clearly see how people were connected.
The Outcome That information led to a coordinated raid, multiple indictments, and the seizure of millions in illegal assets.
Why AI-Powered Investigations Matter
