The unrepentant killer died on October 8, 2022, after being transported from HMP Edinburgh to receive end-of-life treatment for cancer.
Police sat at his deathbed trying to get the terminally ill 76-year-old to shed light on unsolved cases across the UK before his death.
In this short documentary, Mark Williams-Thomas examines the evidence from his investigation into serial killer Bible John, as well as two unsolved cases in Sussex.
Mr Williams-Thomas said: “Over the years I have had the opportunity to thoroughly investigate a number of serial killers. Peter Tobin is by far the most despicable of them all.”
“As Tobin faced his final days in hospital, seriously ill with cancer and undoubtedly in pain, I felt no sadness or compassion for him. He was a despicable man who had no thought for his victims or their families as he brutally took their lives.
“He also did not care about the families of the loved ones he killed and for which he was not convicted.
“He could have easily let go of her pain. Instead, he chose to remain silent and not reveal where his other victims are buried.”
