RHEM LabsInstruct an expert RHEM LABS / FORENSIC SCIENCE LABORATORY
RHEM Labs is a forensic science laboratory providing independent analysis, expert reports and evidence for legal matters.
RHEM Labs works with solicitors, barristers and other instructing parties to examine digital evidence and address the forensic questions that matter to a case.
THE QUESTION BEHIND THE RECORD
“The phone shows X.” Does the underlying evidence sustain that inference? A record may establish an event without identifying who caused it, why it occurred or whether a person knew about it.
We examine the source artefacts, acquisition and system behaviour where necessary, then explain the competing interpretations and limits.
From timestamp to attribution ↗01 / FORENSIC EXPERT WITNESS SERVICES
Start with the disputed inference and the opinion you need. Engagement types describe the work; technical capabilities describe the evidence involved.
Independent forensic reports and expert evidence addressing the question in dispute.
Independent review of digital material, existing findings and the inferences drawn from them.
A focused first assessment of the disputed inference, available material and need for further examination.
Technical conferences with solicitors and counsel to clarify evidence, questions and the scope of an opinion.
Further examination of new material, alternative explanations or a defined issue arising after an initial report.
Participation in expert conferences and preparation of joint reports where applicable to the instruction.
Independent explanation of forensic findings, methods and limitations in proceedings.
02 / RESEARCH & DEVELOPMENT
Casework informs our research. Part of the proceeds from forensic expert work is reinvested into developing methods, tools and knowledge that can support future practice.
Forensic practice → research → new methods and knowledge → better-informed forensic practice.
