Forensic Services
Sexual Offences Service
Cellmark's Sexual Offences Service combines traditional forensic expertise with new and innovative approaches to solving crime. Our service approach was developed by working with one of the UK’s busiest sexual assault teams.
The primary elements of this service comprise search and examination of exhibits, recovery of forensic evidence, presumptive testing, DNA analysis and toxicology. However, Cellmark also provides access to an extensive range of other forensic techniques and services and our lead scientists will advise your investigative team appropriately.
