DNA Scotland Ltd was formed in June 2011 by Director Jacqueline Marshall, following the closure of The Centre for Forensic Investigation at Glasgow Caledonian University.  Ms Marshall recognized the need for the provision of a quality DNA Evidence Review service and to that end; DNA Scotland’s DNA analysis laboratory was established.

Jacqueline Marshall has almost eleven years of DNA profiling and Forensic evidence interpretation including complex and high profile cases. Jacqueline is a Member of the Society of Biology, a Chartered Biologist and a Member of the Chartered Society of Forensic Sciences.  

After graduating in 1992 with an Honours degree in Molecular Biology, Jacqueline joined the HIV Research Team at Leicester University before securing a position at Glasgow University’s Leukaemia Research Centre studying Hodgkin Lymphoma and Childhood Leukaemia.  After eight years as a Senior Research Scientist, in 2003 she became DNA Laboratory Manager in a University of Glasgow spin-out company which focused on Forensic case work, DNA paternity testing, Human remains identification and equine/bovine parentage testing.  Ms Marshall was responsible for the company achieving UKAS ISO 17025 Accreditation and for the competency training of three laboratory personnel.  In 2005 she gained a Diploma in Forensic Medical Science from the Worshipful Society of Apothecaries in London. 

Over the course of her career Ms Marshall has recovered DNA from a very diverse range of crime scene material and objects and has interpreted thousands of DNA profiles including complex mixtures.  She has prepared a large number of reports for Criminal Defence Solicitors and has given evidence at many High Court and Sheriff Court Trials. 

DNA Scotland has its own in-house laboratory with an ABI 310 Genetic Analyser.  At present DNA profiles are produced using the SGM plus system.

Mr Terry Randall joined DNA Scotland Ltd as a consultant in 2011 after taking early retirement from the Scottish Police Service Authority.  He has a wealth of scientific evidence interpretation and brings over 30 years’ experience to every case we deal with.  Terry is a Member of the Society of Biology and is a Chartered Biologist.  

Terry joined the Biology Unit of Strathclyde Police Forensic Laboratory in 1978 as a Forensic Technician after spending five years at the Department of Forensic Medicine at Glasgow University. Within a couple of years he secured a post as a Forensic Scientist and shortly after that the Section Head in charge of Hair and Fibres work. For a further 20 years he was the Section Head in General Biology until, under the SPSA reorganisation, the title changed to Team Leader. To that end, he had responsibility for some 20 members of staff. 

During the majority of his career he ran a team of Forensic Scientists which dealt with the large numbers of serious and violent cases which emanated from the Strathclyde and surrounding areas. This included on average of about 80 murders per year. 

As Team Leader he monitored and maintained the competency of the Biologists to practice.  During the tenure of his employment he maintained a very heavy personal caseload producing Court reports which typically contained DNA interpretation on material recovered from all types of violent crime against the person. He is an expert on body fluids and blood pattern analysis (BPA) and was instrumental in developing a 5-day practical BPA course for trainee Biologists which was run and co-presented by Mr Randall three times during the last 8 years.

As part of the out –of –hour’s crime scene team for over 20 years he attended a very large number and variety of Crime scenes. In over 30 years of employment he produced many reports for the Crown and has presented evidence at hundreds of trials at the High and Sheriff Courts.

All DNA evidence is reviewed by Terry Randall and Jacqueline Marshall with Reports signed by both Scientists.  Both Scientists are available for Consultations and giving evidence in Court.
