Forensic, Attribution & Evidence Integrity Briefings
Longform technical briefings authored from 25+ years of District Attorney’s Office digital forensics and cyber response experience.
Cross-Platform Artifact Correlation: The Unified Timeline
Investigations are too often siloed. A phone report tells one story, a laptop another. But a user lives across multiple platforms.
Strategic defense requires a Unified Timeline. We correlate:
- Health data (Apple Watch/Fitbit) with phone unlock events.
- Cloud sync artifacts (iCloud/Google) with local file metadata.
- Vehicle infotainment data (Berla) with mobile GPS artifacts.
Often, what the state calls "suspicious activity" on a single device is revealed to be mundane when correlated across the user's entire digital ecosystem. We find the data points that prove the defendant was elsewhere or doing something entirely different than alleged.
Digital Evidence & The Jury: Bridging the Clarity Gap
How to present complex forensic findings to a jury without losing them in technical jargon, ensuring the "facts of the case" remain the focus.
Cellebrite Deconstructed: Logical vs. Physical Extractions
A deep dive into why relying on a standard "Logical" report can lead to devastating omissions in criminal defense cases.
The Invisible Chain: Maintaining Forensic Soundness
Why "Chain of Custody" is more than just a piece of paper, and how technical missteps during collection can invalidate entire cases.
IP Address Geolocation: Fact vs. Forensic Fiction
Explaining why an IP address is rarely a "physical address" and how prosecution experts often overstate location accuracy.
Metadata: The Digital Fingerprint of User Intent
Analyzing the "Data about Data" to prove whether a file was intentionally created, moved, or automatically generated by the system.
Deleted Data Recovery: What is Actually Possible?
Setting realistic expectations for recovering "purged" communications from modern mobile and cloud-based systems.

How to dismantle a prosecution expert’s technical testimony by identifying overstatements and methodological shortcuts.
Cross-Platform Artifact Correlation: The Unified Timeline
Using cloud, mobile, and wearable data to reconstruct a defensible unified timeline that contradicts isolated evidence claims.
Email Header Analysis: Reading the Route
How RFC-5322 routing hops, cryptographic authentication signals (SPF, DKIM, DMARC), and server timestamps separate genuine origin from spoofing.
