The Vanishing of Vivienne Cameron Ep 8: The scientific analysis

Episode 8: Once the evidence is analysed, detectives use it to piece together the story. The big question is: does it match the accounts?

Piece by piece, each item of evidence is examined. Even though in 1986, when DNA is not in the tool kit of investigators, scientists easily differentiate between those who bled on the night of the murder.

Naturally, they find Beth’s blood at the scene of her murder. Police also find three drops of blood on the path outside Beth’s back door which is A-type blood – the same blood type as Vivienne Cameron.

During the examination of the Cameron house, Fergus’s blood is found on a couple of items, but the same A-type blood appears on many items examined by police. When and how this got there is not explained.

Even with all the unexplained aspects of the crime scene, the Coroner makes a very specific finding at Beth’s inquest, a year after the murder. He is unequivocal in his conclusions – he finds that Vivienne Cameron contributed to the cause of death of Beth Barnard.
