William has been based in London for 18 years and during this time he has gained a reputation for uncovering vital evidence for defence Counsel in historic sexual abuse cases; evidence that had either been overlooked or bypassed during the Police investigation. This previously undisclosed or undetected evidence has proved to be vital in the subsequent acquittal of the accused.
