KILLER cabbie Christopher Halliwell earns £17 a week behind bars for tobacco and coffee and has ‘a following of autograph hunters,’ according to letters penned from his prison cell.

The 52-year-old double murderer, who will never be released from prison, has also admitted he ‘doesn’t have the energy’ to appeal against the conviction for killing Becky Godden, 20, in 2003, but has not ruled it out.

“The last six months have been a headache, having trawled through 11,000 pages of documents with little sleep,” wrote the father and former Ashbury Avenue resident.

“I’ve no regrets, I told the truth and it didn’t go down well. It is what it is. I don’t know if I’ll appeal. I certainly have plenty of grounds for it but at the moment I’m spent and haven’t got the will for another fight. Not yet.”

Halliwell denied Becky’s murder during a trial at Bristol Crown Court last month. He told the jury he was given £700 by two drug dealers to drive them to the spot where Becky’s remains were found years later in Oxo Bottom field in Eastleach, Gloucestershire. However, his “fairy tale” was thrown out.

Protesting his innocence in the letters, he added: “Short of the deceased walking into court and sitting on the judge’s lap, I was going to be found guilty whatever happened. I went into court to tell it like it was and it was important to me that whatever I had to say came from me, not a lawyer.

“And yes, I laughed at a guilty verdict. I found it ironic that I was found guilty of killing someone I’ve never met.”

The letters, seen by The Sunday Mirror, also suggest he has struck up friendships with pen pals. It has not been stated whom the letters were for but he spoke of how he deserved the life-sentence for the murder of Sian O’Callaghan, 22, in 2011.

He added: “I do deserve the previous life sentence for Sian’s death. I had no right to lose my temper the way I did.”

Halliwell, who is at Category A Long Lartin jail in Worcestershire, is also continuing to take swipes at Detective Superintendent Steve Fulcher, who brought him to justice.

“While he was in the witness box I said to him that it was a pleasure ruining his career,” said Halliwell.

“I’ve got no regrets on that point. His one and only mistake was he threatened my kids and he’s paying for it.”

He has also written about his former hobbies, including restoring classic cars, are “irrelevant now”.

He said: “In 2007-8-9 I restored a canal barge which I intended to live on but I sold it to pay off debts after my divorce. And I used to restore classic cars, one of which is in a museum. I never drank because I never knew when I might have to use my car. A phone call from a customer could come at any hour and I had to be sober.”

Halliwell also revealed he gets letters from autograph hunters and in one letter begged for a photo from his pen pal, known only as Melissa.

He admitted that serving life as a heterosexual meant he would never have another sexual partner.

Halliwell told Melissa: “I like your description of yourself. A photo in the future would be better. Your letter seemed genuine and you now have my curious side thinking!

“I laughed when you wrote you might remain single for a while. Yep, same as. I’m not gay – so it’s guaranteed I’ll be single until I croak!”
