Forensics

Handing over an old phone to forensics before a contentious domestic violence (DV) case is a critical step that can provide valuable evidence. Here are key considerations and steps to ensure the process is handled correctly and maximizes its usefulness in court:

1. Why Forensic Analysis Matters
Preserves Evidence: Forensic experts can extract deleted messages, call logs, photos, videos, and app data that may support your case.
Authenticity: A forensic report adds credibility, showing that evidence has not been tampered with.
Metadata Extraction: Time stamps, locations, and sender/receiver details can help establish patterns of behavior.
2. Steps to Prepare the Phone for Forensic Analysis
A. Do Not Alter the Phone

Do NOT factory reset or delete anything, even if you think it’s unimportant.
Avoid using the phone before handing it over, as new data could overwrite older recoverable data.
Turn it off and keep it in a safe place.
B. Gather Context for the Forensic Expert

Explain key events: Provide approximate dates and details of incidents.
List important contacts: Identify numbers or names relevant to the case.
Specify what to look for: Example: threats via text, call history, location data.
C. Choose a Qualified Forensic Expert

Certified professionals: Ensure they specialize in mobile forensics.
Admissibility in court: Ask if they provide legally sound reports.
Chain of custody: Ensure proper documentation of how the phone is handled.
3. How Forensics Can Help Your DV Case
Prove harassment, threats, or coercion via messages or calls.
Expose deleted evidence (e.g., erased messages or hidden apps).
Confirm manipulation (e.g., doctored screenshots, forged messages).
Validate timelines (e.g., showing where and when calls/texts occurred).
4. What to Expect After the Analysis
A detailed forensic report summarizing findings.
Possibly an expert witness to testify on the phone’s data integrity.
Evidence that strengthens your legal position in court.
If you have any concerns about this process, consider discussing it with your lawyer to ensure everything is handled in a way that supports your case. … Read More Forensics

How Deleted Data Recovery Works

Forensic Imaging: Experts use specialized tools (like Cellebrite, Magnet AXIOM, or XRY) to create a bit-by-bit copy of the phone’s storage. This process captures not only active data but also residual or deleted data. Metadata Analysis: Examines remnants of file system metadata to locate and piece together deleted files.File Carving: Forensic software searches for file signatures in unallocated space (areas of storage marked as free) to reconstruct deleted files. Data Sensitivity: Handling illegal or sensitive materials (e.g., child exploitation images) requires adherence to strict legal and ethical guidelines to avoid contaminating the evidence or committing new offenses.… Read More How Deleted Data Recovery Works
