Professor Ronald C Denney BSc, Hon DSc, PhD, CSci, CChem, FRSC, FCSFS has been a consultant for more than thirty years and is a Fellow of the Royal Society of Chemistry, a Fellow of the Royal Society of Medicine, a Fellow of the Chartered Society of Forensic Scientists, a member of the International Council on Alcohol, Drugs and Traffic Safety, and a member of the International Association of Forensic Toxicologists.He has worked in areas of drug synthesis, analysis, pharmacokinetics and DNA interpretation, and has also provided a consultancy service in shipped and transported goods. He is frequently called to give expert evidence in court cases and is supported by an administrative team, enabling him to provide a rapid and efficient forensic service.
1. A typical drink-drive case will be a post-driving drinks defence or a laced drinks special reasons plea involving calculations using the Widmark equation to establish whether or not the extra alcohol has been responsible for the motorist producing a breath or blood alcohol value in excess of the legal limit.
Similar calculations are used involving metabolic rates for alcohol with respect to alleged offences of motorists being 'in charge' of a motor vehicle with a breath alcohol level in excess of the legal limit. Back calculations relating to road accidents and assaults are also carried out.
2. Drugs cases may be concerned with possession and of establishing whether or not a person was under the influence of drugs at a time when an alleged crime was committed. Cases may also be concerned with whether or not a driver had a drug level in excess of the specified limit.
3. Checking DNA results and interpretations arises in assault, rape and sexual abuse cases and even in some drug cases.
4. Some crimes involve assaults from the use of dangerous chemicals. In these instances, analysis, knowledge and experience of the chemicals is necessary. A similar situation arises with industrial injuries arising from chemically polluted atmospheres.
5. A typical burglary may lead to detailed studies with interpretation of footprints from the location, analysis of fibres of clothing left behind and analyses of glass particles on clothing from someone allegedly involved with the crime.
Professor Denney has an extensive scientific background which has involved working in the chemical industry as well as a university lecturer and research worker in addition to his many years providing a consultancy service. As a result he has travelled widely and is familiar with having to meet very short deadlines in legal and insurance cases. Preliminary technical advice will be provided on request and inspection and testing of samples carried out if required.
Until March 1995 he was Principal Lecturer and Reader in Organo-Analytical Chemistry at the University of Greenwich and now runs his own business as a Forensic Scientist and Industrial Consultant, and has been visiting Professor in Forensic Science at Kingston University. He specialises in the areas of alcohol, drugs, dangerous chemicals and DNA interpretation and is considered to be one of the country's leading authorities on the subject of drinking, drugs and driving.
He is frequently called to give evidence as an expert witness in murder, assault, rape and burglary cases involving the abuse of alcohol or drugs and has also been involved in several major trials concerning the synthesis of illegal drugs.
Professor Denney has written numerous technical books, including four on alcohol, drugs and accidents, as well as papers and articles on alcohol, drugs and the law.
