Mark has over the last decade reported on nearly all of the biggest crime stories including: Oscar Pistorius, The Alps murders, Tia Sharp murder, Claudia Lawrence murder, the murder of Alice Gross and the disappearance of Madeleine McCann.
One of Mark's greatest skills is his ability to get exclusive access and interviews with key people related to the cases.
Alongside Mark’s television and media work he also runs a number of high-profile investigations which attract no media attention. His level of confidentiality and trust he builds is what enables him to undertake so successfully the work that he takes on.
David has worked in the criminal justice system as a specialist for over 20 years.
He has been involved in some of the countries most high-profile cases. Having both defended criminal cases and been involved in complex prosecutions, David is able to draw upon his vast experience and adopt a forensic approach to the cases he is involved with.
David, and Mark Williams Thomas, have together been involved in complex investigations both to domestically and internationally, and often cases which attract considerable publicity.
Utilising his extensive skills over the last 20 years, it was inevitable that David would move into the field of specialist investigations. He has developed and nurtured trusted colleagues within the profession, all of whom sharing the same interest and passion for achieving justice across the investigative spectrum.
