Wearside Jack: When Yorkshire Ripper Peter Sutcliffe wrote to Wearside Jack hoaxer John Humble in prison
'You have blood on your hands' - the words of Yorksire Ripper murderer Peter Sutcliffe to John Humble.
Today, after reports of the death of Humble aged 63, we look back to when the story of Wearside Jack took a bizarre twist as the real Ripper wrote to his impersonator in prison.
Sutcliffe, who was convicted of murdering 13 women and attempting to murder seven others in 1981, wrote to hoaxer John Humble in prison shortly after the infamous Wearside Jack hoaxer was finally jailed.
It took 25 years before he was brought to justice thanks to DNA evidence. In March 2006 he admitted four charges of perverting the course of justice and was jailed for eight years.
In his letter, widely reported at the time, Sutcliffe blamed Humble for the deaths of his final three victims.
"You could have saved those three women, John. You have blood on your hands," he wrote.
"You could even end up in Broadmoor with me. That is where you belong."
Sutcliffe's letter was also said to read: "I have just heard that you got eight years in prison on Tuesday for the crimes you committed.
"I am not surprised that you got that length of time because what you did was very bad indeed.
"You have now had your 15 minutes of fame and you have reopened old wounds again and put me back in the media spotlight.
"I do not need this now or ever again. The same thing will happen when you are released.
"I hope you get some treatment for your problems, John, because you are very ill indeed."
However, the letter also tried to strike a friendly note, assuring him "Be strong, God will look after you," and ending"Your friend Peter."
