Location data is among the most persuasive — and most misunderstood — categories of digital evidence. Prosecutors routinely present geolocation data as definitive proof of presence. It is rarely that simple.
Even the primary forensic software providers, such as Cellebrite, issue a clear directive: Do not rely solely on the accuracy of location information provided within an automated extraction.
Automated tools parse coordinates from various databases — such as application logs, photo metadata, and system caches — but they cannot always account for the context or reliability of that data. To be legally and forensically sound, geolocation must be verified through independent sources, such as:
Mobile devices often store "cached" locations or rely on low-accuracy signals that can place a device miles away from its actual position. Without a forensic expert to interpret the source of the coordinates, the prosecution may present a "dot on a map" that is fundamentally inaccurate or misleading.
The example below illustrates a real-world case of how automated forensic reporting can place a device miles away from its true location. Two data points recorded just one minute apart show a staggering geographical discrepancy.
The Cellebrite-recorded GPS data places the device in the eastern part of Las Vegas.
Independent cell tower records place the device 11 miles to the west, near Summerlin.
The Legal Implication: If the prosecution relies solely on the 01:58 A.M. timestamp, they may incorrectly place a defendant at a crime scene. Without a forensic expert to identify and cross-verify these conflicting data points, this 11-mile error could go unchallenged, leading to a fundamentally flawed narrative of the facts.
Never accept a "dot on a map" as absolute truth. We provide the independent verification necessary to ensure location evidence is accurate and defensible.
Forensic Cyber Investigations performs independent cell tower analysis and location data review to identify errors, overstatements, and exculpatory data in government forensic reports.
