Event Abstract

This presentation looks at a real-life Murder Investigation, the conviction of the accused and the subsequent overturning of that conviction.

John Kennedy, a Consultant Forensic Scientist with the Government owned Forensic Science Service [FSS] had been  instructed by the Crown. Having undertaken a preliminary review of the evidence, John  cautioned the Police in relation to the reliability of the evidence which formed a major plank of the Prosecution case and recommended a particular forensic process to address the issues at hand. John had also recommended that, depending on his findings from undertaking that forensic process, it should be independently reviewed by a suitably experienced and competent Expert.  The Police ignored John’s advice and travelled to Las Vegas where, in their words, they got the right result. The American Expert gave evidence at Trial and the accused was convicted and sentenced to life imprisonment. 

The fallout from this case has been huge, resulting in the Code of Ethics for Experts  within this forensic discipline being changed. An interview featuring John’s experience in this case is now shown to Police Officers worldwide as part of their ethics training. 

The American Expert was investigated by the Police in Oklahoma after receiving complaints regarding alleged similar work by that Expert. The extraordinary and traumatic events that unfolded as a result of that investigation will be revealed at the end of John’s presentation.
