Snapchat Location Data Clears Juvenile of Serious Charges
A juvenile defendant had no alibi — until forensic extraction of Snapchat data built one.
- Mobile device acquisition using write-blocked forensic imaging (Cellebrite UFED)
- Snapchat native data extraction: location pings, session metadata, and snap timestamps
- Forensic timeline reconstruction correlating device activity with carrier GPS records
- Expert report documenting methodology, findings, and chain of custody for court submission
The forensic timeline built from Snapchat location data directly contradicted the prosecution's theory of the case. The defense attorney presented the findings at a preliminary hearing, resulting in the charges being challenged on evidentiary grounds. The engagement demonstrated how native app data — invisible in screenshots — can establish a legally defensible alibi.
300,000 Emails Narrowed to 30,000 Relevant Documents
An overwhelmed legal team faced a massive, unfocused email corpus — scope needed to be cut by 90%.
- Custodian analysis: identifying the 12 key custodians most likely to hold responsive material
- Date range scoping tied to key events in the litigation timeline
- Iterative keyword refinement using proximity operators and Boolean logic to reduce false positives
- De-duplication and near-duplicate identification across the custodian set
- Privilege log structuring and attorney-client communication tagging
- ESI protocol documentation suitable for court filing and opposing counsel review
The refined strategy reduced the review corpus from 300,000 to approximately 30,000 documents — a 90% reduction — while preserving all records material to the claims and defenses identified in the complaint. The culling methodology was documented and defensible under FRCP Rule 26. Review costs dropped in proportion and the case proceeded to discovery on schedule.
Correct Prenuptial Agreement Version Proven Through Forensic File Timeline
Two versions of a prenuptial agreement existed — only one was actually signed, and the metadata proved which.
- Forensic imaging of both parties' laptops and examination of file system metadata
- Email server subpoena analysis: reconstruction of transmission timestamps and relay chain
- Cloud account forensics: OneDrive and Gmail version history for both document files
- Metadata extraction: creation timestamp, last-modified, author field, and printer driver artifacts
- Cross-correlation of device activity logs with flight records to establish the drafting timeline
Metadata analysis established that one version was created, modified, and transmitted during a flight — before the couple landed. The opposing version's creation timestamp post-dated the wedding by three weeks. The forensic report provided the court with a documented, reproducible methodology for the timeline finding. The outcome turned on digital evidence that neither side's narrative had accounted for.
EDR Data Reconstructs Collision Timeline in Disputed Liability Case
Both drivers claimed the other ran the light — the vehicle's event data recorder settled it.
- Event Data Recorder (EDR/black box) download from both vehicles using Bosch CDR equipment
- Pre-crash speed, braking, and steering input data extraction from the 5 seconds prior to impact
- Airbag control module data correlation for impact timing and severity
- GPS telematics data subpoena from both vehicles' connected services
- Forensic report cross-referencing EDR outputs with physical evidence at the scene
The EDR data from one vehicle showed no braking input and sustained highway speed through the intersection at the moment of impact — directly contradicting the driver's testimony. The GPS telematics record confirmed the timeline. Liability was established on the forensic record rather than competing witness accounts, enabling the plaintiff's attorney to resolve the matter without trial.
Departing Employee's Data Exfiltration Documented Before Devices Were Wiped
A senior employee left and a competitor launched an identical product line two months later — the question was what they took.
- Emergency preservation of devices before wipe completion using write-blocked imaging
- File system artifact recovery: LNK files, jump lists, MRU lists, and shellbag analysis
- USB device connection history extraction from Windows registry hives
- Cloud sync client log analysis (Dropbox, OneDrive) showing external file transfers
- Email metadata review for large attachments sent to personal accounts in the departure window
- Forensic timeline correlating file access events with the employee's badge swipe records
Forensic artifacts recovered from the partially wiped devices documented over 400 proprietary files accessed in the employee's final week, with USB connection timestamps matching a personal storage device brought to the office on the last two days of employment. The forensic report was admitted over a Daubert objection. The matter resolved during discovery after the opposing party's counsel reviewed the findings.
Fraudulent Wire Transfer Traced Through Email Compromise Chain
A business received what appeared to be a legitimate wire instruction from a trusted vendor — and lost six figures.
- Email header forensics: full SMTP relay chain analysis for the fraudulent instruction thread
- SPF/DKIM/DMARC authentication record review to identify spoofed sender infrastructure
- Office 365 audit log subpoena: login events, IP addresses, and mail rule configurations
- Inbox rule analysis showing automated email forwarding configured by the attacker
- Threat actor infrastructure documentation for the fraudulent domain registered weeks prior
- Timeline reconstruction establishing when the legitimate account was first accessed without authorization
Email header analysis established that the vendor's email account had been compromised 18 days before the fraudulent wire instruction was sent. The attacker had configured an inbox forwarding rule that silently redirected vendor correspondence. The forensic report documented the attack chain and was submitted as evidence in the civil proceeding. The findings also informed the client's cybersecurity insurer's coverage determination.
