Sutcliffe, who is serving a life sentence after murdering 13 women and attempting to kill seven more between 1975 and 1980, told some he would love to spend time with them and urged others to visit him behind bars, according to the Sun.
In one note Sutcliffe also suggested there is “something not quite right” about the disappearance of three-year-old Madeleine McCann in Portugal in 2007 and alluded to discredited theories at the time falsely incriminating her parents, Kate and Gerry McCann.
The killer also describes his friendship with paedophile Jimmy Savile, who had access to Broadmoor, saying he gave the presenter a portrait he painted of him “on one of the many occasions he popped in for a chat in my cell”, and also talked of how his ex-wife Sonia still visits him.
In a letter to one fan who visited him in prison, he told her “you looked gr8 in that outfit”, wrote to a different admirer “I’m thinking of you 24/7” and asked another “By the way, have you found a steady boyfriend yet?”
Sutcliffe, 69, wrote to one: “I’m way up on cloud 9 after seeing you today I can tell you. Ok then gorgeous take care for now.”
The letters, some of which are decorated with stickers such as hedgehogs, love hearts and butterflies, were sent over a 10-year period under the name Peter Coonan - his mother’s maiden name - the newspaper claimed. In one he reveals he goes to sleep with a teddy bear.
Sutcliffe has a large number of fans who write to him, speak with him by phone and shower him with gifts.
