Streamlined Forensic Reporting – the hidden truth
Streamlined Forensic Reporting (SFR) was rolled out nationally in April 2013. The CPS guidance document states that “SFR is a revised case management procedure for producing forensic evidence at court, which seeks to reduce unnecessary costs, and delay in the criminal justice system. The process takes a more proportionate approach to forensic evidence through the early preparation of a short report that details the key forensic evidence the prosecution intend to rely upon. The aim is to achieve early agreement with the defence on forensic issues but where this cannot be achieved in the first instance, to identify the contested issues.”
The first stage SFR1 report is not a witness statement or report to which the Criminal Procedure Rules apply. It is, at this stage, difficult for the defence to determine whether they dispute the evidence being provided as the information that the SFR1 provides is often nothing more than a bland description of the analytical result, with little if any background or interpretational information. Such reports have been the only account of the forensic evidence for some cases where we have been instructed. Take this example:
- A screwdriver recovered from a burglary had been examined by the DNA unit of a forensic provider, and a DNA profiling result had been obtained from the handle.
- A profile had been loaded to the National DNA Database and a match report had been generated.
- The police force had taken the information from the match report and used it to complete an SFR1. Note there was no involvement of the forensic scientist at this stage.
- This stated that a match existed between the DNA sample taken from the crime scene and the defendant, and that this match was derived from a partial DNA profile.
On the face of it, this appears straight forward, but importantly there was no information on the SFR1 regarding:
- The number of DNA components comprising the partial profile
- Whether any other DNA had been detected
- A statistical evaluation of the match
- Evaluation of the transfer and persistence of DNA within the case circumstances.
When we were asked to review this result we found that the DNA profiling result was in fact a mixture of DNA from at least 3 people. There was an apparently stronger contribution which matched the defendant, but this was not clear across the whole result. Following our report, further work was carried out by the forensic provider who ultimately provided a statement which concluded that the result was unsuitable for a standard statistical evaluation due to the number of potential contributors of DNA to the result.
Had the SFR1 alone been put before the court in the case above, the information it provided would have been at best incomplete, and at worst misleading. It is important that the defence make it clear as early as possible in proceedings if they wish to contest the forensic evidence so that an SFR2 or full statement can be provided by the forensic provider. However, in the case example given it was almost impossible from the SFR1 for the solicitor to know whether it was worth contesting the evidence and requesting that an SFR2 report or full statement was produced by the scientist. Even when a statement was produced, there was no evaluation of the transfer and persistence issues pertinent to the case. The defendant stated that tools that he used in the course of his work had been stolen from his vehicle some time prior to the offence and that the screwdriver could have been one of these tools, thus providing an alternative explanation for the presence of any of his DNA on the item.
