Short answer: Triage Forensics helps criminal defence lawyers test the digital evidence police rely on. That covers mobile phone forensics (messages and deleted data), location timeline reconstruction, call detail record analysis and video authentication, delivered through independent, court-ready expert reports.
For a defence lawyer, digital evidence can be the difference between conviction and acquittal. Police frequently build cases around phone messages, GPS locations, call records and CCTV footage. An independent forensic specialist helps you test that material rather than take it at face value.
Core specialisations for the defence
- Mobile phone forensics: extraction and analysis of iPhones, Androids, SIMs and memory cards.
- Deleted message recovery: retrieving communications that may have been overlooked or removed.
- Location timeline reconstruction: mapping where a device was at relevant times to corroborate or challenge accounts.
- Video forensic authentication: examining prosecution footage for editing, tampering or AI generation.
- Call detail record (CDR) analysis: working with the phone network records produced by police.
How independent expertise helps the defence
Prosecution material isn’t always what it appears. An independent review can:
- Challenge disclosure completeness. Is all relevant data present, or has something been missed?
- Test extraction methodology. Was the device handled properly? Could findings reflect how the data was collected?
- Re-examine interpretation. Location data is often presented as fact but is nuanced. GPS accuracy varies, and “device here” doesn’t equal “user here”.
- Identify alternative explanations. Deleted messages or app activity may tell a different story from the prosecution narrative.
- Provide counter-expert evidence to balance an opposing expert at trial.
Why location data deserves close scrutiny
Prosecutors often present GPS and cell tower data as near-certain proof of where someone was. In reality:
- Cell tower records indicate the area a serving tower covers, not an exact position.
- Wi-Fi and Bluetooth add context but have their own limits.
- Multiple people may share a device or account.
We explain these limitations to the court in simple terms, and that is frequently decisive for the defence.
Reports that hold up under scrutiny
Defence work demands reports that are:
- Compliant with Australian evidence requirements and applicable expert witness codes of conduct, including the duty to assist the court independently of the client.
- Rigorous, so they survive cross-examination.
- Clear enough for a judge and jury without technical training.
Where matters go further, we can also give oral expert evidence in person.
Working alongside your team
Our role is independent: not an advocate, but a rigorous examiner of the digital record. That independence strengthens your case because the findings are seen as objective rather than partisan.

Frequently asked questions
What does Triage Forensics specialise in for criminal defence lawyers?
Mobile phone forensics, deleted message recovery, location timeline reconstruction, video authentication and call detail record analysis, helping the defence test rather than accept prosecution digital evidence.
How can an independent expert help the defence?
An independent review challenges disclosure completeness, tests extraction methodology, re-examines how location data has been interpreted and provides counter-expert evidence to balance opposing experts at trial.
Why should location evidence be scrutinised?
Cell tower records show the area a tower covers rather than an exact position, GPS accuracy varies indoors, and multiple people may share a device. A forensic expert can explain these limits to the court in simple terms.
Are defence reports admissible in Australian courts?
Defence reports are prepared to meet the standard admissibility requirements for expert evidence: relevant, based on specialised knowledge, and transparent enough to be tested under cross-examination. Admission is always a matter for the court.
