The series will reveal the inside stories of some of the UK’s most complex major crime cases, and how expert witnesses helped crack them using forensic science.

Each episode will see Baptiste explore two different cases, and hear from those who solved them. Among those featured are The World’s End murders of 1977, one of Scotland’s longest running investigations, the Rochdale Ripper, who was captured using forensic imaging, and two crimes solved by the examination of pollen at a murder, and fibres in a car crash.

Ashley John Baptiste said: “It has been truly fascinating to learn how the intelligence and expertise of some remarkable individuals has helped solve some of the biggest criminal cases known to the British public.”

Expert Witness will air on BBC One mornings in autumn 2021.
