Forensic Biology, DNA and Crime Scene Examination
Forensic biology plays a critical role in the investigation and interpretation of violent and sexual offences, providing scientific insight into how biological evidence was deposited, transferred and analysed.
At Forensic Access, our experts work across the full forensic biology continuum, from crime scene examination and body fluid identification through to DNA interpretation and blood pattern analysis. We are routinely instructed to review evidence, advise on investigative strategy, and provide independent expert opinion where the interpretation of biological evidence is contested or complex.
Our forensic biology experts include highly experienced, court‑going scientists with extensive experience working within prosecution forensic service providers, as well as delivering independent expert services to the defence. Our role is not simply to report results, but to ensure the scientific evidence is properly understood and fairly interpreted.
Types of Forensic Biology Case Instructions
Our forensic biology, DNA and crime scene experts are instructed across a wide range of cases, particularly where the interpretation of biological evidence is disputed or complex.
We are commonly instructed in cases involving:
Sexual offences, including issues of consent and activity level interpretation
Assaults and homicides involving competing accounts of events
Allegations where secondary transfer, persistence or contamination are in issue
Historical investigations and cold case reviews, including the re‑evaluation of previously examined evidence
Appeals and post‑conviction reviews
Cases where the absence of biological evidence is relied upon or challenged
Our experts work closely with legal teams to ensure the scientific evidence is considered in its proper context and that alternative explanations are explored where appropriate.

Blood Pattern Analysis
Blood pattern analysis can provide valuable insight into the events that led to bloodshed, including the nature of the incident, the positions and movements of individuals involved, and the sequence of actions.
Our blood pattern analysts are experienced in both scene‑based and laboratory‑led casework and are frequently instructed where interpretation of blood evidence is disputed.
Our services include:
Blood pattern analysis at scenes and from photographic or video evidence
Reconstruction of events involving bloodshed
Interpretation of impact, cast‑off, transfer and void patterns
Evaluation of alternative propositions and competing accounts

Body Fluid Analysis
The detection, identification and interpretation of body fluids is central to many forensic investigations, particularly in cases involving allegations of violence or sexual activity.
We provide expert input where the presence, absence or interpretation of body fluids is critical to the issues in dispute.
Our services include:
Identification and interpretation of blood, saliva, semen and other body fluids
Review of presumptive and confirmatory testing
Assessment of transfer mechanisms and persistence
Evaluation of contamination risks and sampling strategy
Expert reporting and courtroom evidence
DNA Evidence and Interpretation
DNA evidence is often perceived as definitive, yet its interpretation can be complex and highly dependent on context, methodology and assumptions made during analysis.
Our DNA experts provide independent assessment of DNA evidence to ensure conclusions are scientifically robust and fairly presented.
Our services include:
Review and interpretation of DNA profiles and mixtures
Assessment of low‑level and complex DNA evidence
Evaluation of laboratory methods and reporting
Consideration of transfer, secondary transfer and persistence
Expert witness reports and joint expert discussionss
Crime Scene Examination
Early forensic decisions can have a lasting impact on the evidential value of a case. Our crime scene experts support investigations by reviewing scene strategy, examination methods and evidential findings.
We are instructed both proactively and retrospectively to assess whether scenes have been examined appropriately and whether alternative interpretations should be considered.
Our services include:
Crime scene examination and reconstruction
Review of scene management and forensic strategy
Evaluation of scene findings in the context of case circumstances
Identification of missed opportunities or alternative explanations
Expert reporting and court attendance
Expert Reports, Reviews and Defence Case Support
Forensic Access prepares independent expert reports and case reviews for use in forensic investigations and legal proceedings.
Our experts are instructed to review and critically assess forensic biology and DNA evidence obtained by the prosecution, evaluate laboratory methods and conclusions, and advise on evidential strengths, weaknesses and alternative interpretations at all stages of a case.
