In this talk I will show how chain event graphs can be used to construct possible storylines for displaying the time evolution of events and evidence in criminal cases. These chain event graphs can both be used to investigate possible arguments when drawing up a case and to make probabilistic assessments of the strength of evidence when prosecuting or defending. I will give two examples – a drugs on banknotes case and the case of the murder of Meredith Kercher. To finish the talk I will discuss the role that statistics and probabilistic reasoning can play in criminal cases, including in the recent Lucy Letby case, and highlight where greater collaboration is needed between statisticians and those in the legal sector.
