The forthcoming new series of Murder Case features interviews with the families of the victims, the media who covered the cases as well as the police who brought the perpetrators to justice.

David Harron, commissioning executive, factual at BBC Scotland said: “Murder Case is one of our most important brands at BBC Scotland and is hugely popular with the audience. Through its exceptional access to the Major Investigations Team of Police Scotland it has provided the audience with a real insight into the work of detectives on these cases.”

Vari Innes, executive producer at Firecrest Films said: “Filmed over the course of two years from investigation to trial, with the support of Tony and Keisha’s families, these new cases offer unparalleled access to Police Scotland’s Major Investigations Team, following their quest for answers and justice for the victims and their families. We are proud and privileged to be entrusted with sensitively bringing these harrowing cases to light.”
