Jonathan Whitaker of Principal Forensic Services talked to Channel 4 about the use of familial DNA testing which it is hoped will solve a murder on a train from 25 years ago. Jonathan led the team of scientists who developed familial DNA searching in 2002.

 Another scientist from Principal Forensic Services, Julie Allard, was also involved in the investigation of this case and preparation of the DNA profiles.  Blood which the offender left at the scene was originally subjected to blood grouping by another scientist who attended the crime scene and first dealt with the case.  Remnants of the bloodstaining were retained at the FSS London laboratory and in the 1990s Julie submitted samples from these for DNA profiling. The results were loaded onto the National DNA Database but no matches have been found. Hopefully the familial DNA tests now being done will help identify the offender.

PFS Presents: The Intergrity of Scientific Evidence

Understanding and Minimising the Risk of Contamination in the Forensic Process, Fri 21st Sept, The Royal York Hotel, York

This very successful one day workshop designed and presented by PFS was held in conjunction with the Forensic Science Society at the Royal York Hotel.   The day was a unique opportunity to meet PFS practitioners involved in different parts of the forensic science process, from crime scene through to interpretation of scientific evidence and its presentation in court.  The day was attended by a large number of delegates representing forensic scientists, crime scene examiners, lecturers, students and police officers wishing to enhance their understanding of how to minimise, control and manage the risk of contamination in the whole forensic process.  Break-out groups featured lively debate discussing current practices for detecting contamination and tools for the future in crime scene management, GSR, DNA & body fluids and quality systems.  The output from the break-out groups proved to be very constructive and the issues discussed were captured and following the workshop shared with delegates and the Forensic Regulator.  We hope this will translate to raising awareness and standards in this area.

The learning points for the day included:

  • Identifying the risks and consequences of contamination events.
  • Looking at key practices and appropriate standards needed to minimise contamination in the whole forensic process.
  • Exploring ways in which contamination can be detected and monitored.
  • Identifying the mechanisms of contamination using real examples.
  • Discovering interpretational aspects of results drawing on assessment and interpretation principles to help evaluate whether contamination has occurred.
  • Covering the development of new standards and policies in relation to contamination.

The theme ‘Enhancing the Effectiveness of Prosecutors in a Challenging Environment attracted’ thirty-nine delegates from the Caribbean British Overseas Territories and the Commonwealth Caribbean countries, along with 23 Cayman Island delegates, comprising prosecutors and RCIPS personnel including crime scene managers and police officers.

Delegates at the workshop received training in critical forensic techniques, pathology in homicides, transnational crimes’ issues and the care of victims in serious crimes. Experts from PFS provided forensic science training in blood spatter pattern analysis, fingerprint identification, footwear marks and gunshot residue. The workshop also underscored the principles of evidence-based cross-examination, the role of the defence expert witness and the effective prosecution of transnational crimes.

Press Release 

PFS Ltd:

New forensic science company draws on over 250 years’ experience

London, 2 April 2012 … With over 250 years experience between them, today sees 11 internationally renowned forensic scientists join forces to launch Principal Forensic Services Limited (PFS Ltd.) – estimated to be one of the most concentrated pools of forensic science talent operating in the UK today.

PFS Ltd. will provide impartial forensic science consultancy, training, advice and casework capability to defence, prosecution and regulatory bodies. It will also work with the UK criminal justice system to drive the development of nationally recognised standards for the UK forensic science market.

The PFS Ltd. Directors were all leading scientists at the recently closed Forensic Science Service (FSS) providing expert analysis in a catalogue of major national and international criminal investigations including: the PIRA campaign 1989-1993; the murder of Rhys Jones; the identification of Tsar Nicholas II and his family; the murder of PC Dunne; the appeal of James Hanratty and the disappearance of UK backpacker Peter Falconio. PFS will continue to provide unbiased and robust expert testimony worldwide.

The specialist services available include DNA, Body fluids, Blood Pattern Analysis (BPA), Firearms, Gunshot Residue (GSR), Toxicology, Marks and Traces (e.g. footwear, toolmarks, paint and glass) and Quality Review.

With the UK’s forensic science market facing significant challenges and changes as a result of the closure of the FSS, the launch of PFS Ltd. ensures that these skills are maintained for use across the UK’s criminal justice system. In addition, it offers the depth and breadth of experience required to robustly take on the review of casework along with the ability to review and advise on any quality issues that may arise in the future.

Mark Mastaglio, one of the Directors of PFS Ltd., comments: ‘With our passion for forensic science, it seemed natural to bring together our combined skills under the umbrella of PFS Ltd. rather than allowing our combined experience to disperse across an increasingly fragmented market place.’

‘One of our strengths is that we bring together our skills to assess multi-disciplinary issues that may arise in a case as well as having the experience required to peer review each other’s work for court room purposes.’

The PFS Ltd. team consists of: Julie Allard, David Baldwin, Mike Barber, Gillian Leak, Mark Mastaglio, Sue Pope, Mike Scott-Ham, Angela Shaw, Kevin Sullivan, Dr Gillian Tully and Dr Jonathan Whittaker.


Notes to editors:

  • Principal Forensic Services Ltd. is an independent partnership of world-leading forensic scientists covering each of the main forensic science disciplines. It offers impartial consultancy, training, advice and casework capability to both the defence, prosecution and regulatory bodies in the UK as well as abroad.
  • The Directors of PFS Ltd have also been involved in the following investigations: the “Unibomber” investigation, the murder of Jill Dando, the  murder by Kenneth Noyes, the HMS Astute murder and attempted murders, the unmasking of bogus defence “expert” Godwin Onubogu.
  • Background to the forensic science market:
    • According to National Police Improvement Agency figures, police budgets attributed to forensic science providers has shrunk from £175 million in 2008/09 to £138 million by 2010/11. With increased pressure on police budgets, following the Government’s spending review; estimates for the police budgets allocated in 2011/12 are as low as £80 million.
    •  It is thought that all forensic science providers have seen a reduction in the number of submissions received from police forces across the UK as a result of budget pressures.
    • The introduction of competitive tender processes has led to the fragmentation of different casework disciplines across multiple forensic science providers rather than allowing a holistic case review.
    • The Forensic Science Service (FSS) was the UK’s largest forensic science provider supporting over 120,000 cases per year and employing approximately 1300 forensic scientists. Following the government’s decision to progressively wind down the FSS, it officially ceased operations at the end of March 2012.
    • It is estimated that only 10-20% of former FSS scientists have remained in the industry leading to a massive reduction in the forensic science skills available in the UK when compared to the rest of the world.
