As ownership of mobile phones, laptops, tablets and other electronic devices continues to skyrocket, digital evidence is becoming an increasingly important part of criminal investigations. To help identify suspects and build strong cases against perpetrators, the Sheriff’s Office must sift through hundreds of gigabytes of data each year.
“During the course of a criminal investigation, it’s common for officers to seize hard drives and flash storage devices,” says Guy Cranor, special deputy – computer forensics analyst at Clallam County Sheriff’s Office. “To support our detectives with their work, we need to extract as much relevant information as we can from those devices—ranging from text documents, photos and video files to metadata showing when users were logged in and which websites they may have visited.”
External processing introduces delays
To ensure digital evidence is admissible in court, law enforcement agencies must follow strict data extraction, processing and reporting procedures. In the past, the Sheriff’s Office relied on an external lab to perform all these tasks, adding significant lead times to some investigations.
“Previously, the Sheriff’s Office lacked the capability to process digital evidence,” Cranor says. “Instead, an officer would drive seized storage devices to a specialist forensic lab to preserve the chain of custody—a six-hour round trip. Crucially, it often took several months to receive the results, potentially delaying criminal investigations.”
Enabling advanced digital forensics
To accelerate digital forensics processing and better protect residents across Clallam County, the Sheriff’s Office selected OpenText™ EnCase™ Forensic, a court-proven solution for identifying, collecting and preserving forensic data from a wide variety of devices.
“One of the things I appreciate the most about the OpenText solution is that it supports our entire digital forensics process from end-to-end,” Cranor says. “While we use additional tools to carry out tasks such as cloning drives or analyzing image metadata, it’s the OpenText solution that allows us to find and act on evidence—for example, by highlighting information of interest for detectives and building reports for prosecutors.”
Hitting the ground running
Using an OpenText Learning Subscription, Cranor rapidly got up to speed with the solution.
“The training I received through our OpenText Learning Subscription was extremely valuable,” Cranor recalls. “Even though the in-person sessions had to be carried out remotely because of the COVID-19 pandemic, I was very impressed by the quality of the instruction. The initial foundation class helped me to hit the ground running from day one, and the solution is now supporting active investigations at Clallam County Sheriff’s Office.”
