Specialist Case Knowledge:
Martin has unique and industry-leading knowledge of many of the largest criminal cases in recent years, including having gained access to witnesses and their statements, legally privileged information, confidential police files, court documents and obtaining new evidence.
Some of the cases for which Martin has unique, specialist in-depth knowledge of include;
Michael Stone and the murders of Lin and Megan Russell: Martin has been assisting Michael’s legal team in relation to the new suspect and has also provided the team with new evidence that gives Michael a rock-solid alibi. Martin’s inside-knowledge of the case dates back as far as the date of the murders in 1996, and includes a lot of previously unreleased information about the crime scene, the original suspects and claims made by others.
Madeleine McCann: Having studied every aspect of this case in great detail, including various suspects such as Christian Bruckner; Martin has used his inside connections in the Portuguese police as well as contacts with various legal teams to gain a huge amount of information that has never been released to the public. His own investigation has identified that the evidence against Bruckner is actually a better fit to a couple of other people who have never before been identified in relation to the investigation – Martin has submitted his findings to the Met’s Operation Grange and continues to work on the case.
Levi Bellfield: Working as part of Mark Williams-Thomas’ team, Martin has had direct access to Bellfield, his files and unreleased police evidence. As well as sitting in on several phone calls with Bellfield, Martin has thoroughly investigated each of Bellfield’s new claims, such as the Murders of Elizabeth Chau, Melanie Hall and Judith Gold (Silver).
Missing Persons Cases: Again, as part of Mark Williams-Thomas’ team, Martin has worked on, and thoroughly investigated every angle and piece of evidence in cases such as Jay Slater, Nicola Bulley, Lee Boxell, Nicola Payne and more. (around 140 murder, missing persons and fraud cases in total)
In addition, Martin has studied various fields of forensics, geographical profiling and human trafficking, gaining, when required, any certifications and knowledge for the specific cases that he is working on.
