Independent Forensic DNA Review
Roebuck Forensics provides independent forensic science review and expert witness services for criminal lawyers across Australia and New Zealand.
When forensic findings appear “strong”, the real question is often:
What does the evidence actually support – and what does it not?
I help criminal lawyers properly interpret forensic results, identify assumptions and limitations, and translate complex technical material into clear, robust positions that can be used in advice, negotiation, committal preparation, and trial.
– DNA interpretation & likelihood ratios
– STRmix and mixture complexity
– Biological fluid testing (blood / semen / saliva)
– DNA transfer, contamination & persistence issues
– Bloodstain pattern analysis (BPA) review
– Cross-examination and trial support
If you have received a forensic report and need clarity early, I can help.
