A woman has claimed that she was stalked by Swindon double-murderer Christopher Halliwell years ago. 

Speaking to the Mirror, the female witness, an anonymous woman in her 60s from Bridlington, Yorkshire, said she bumped into the Swindon killer on several occasions. 

She has also suggested that he could have killed missing chef Claudia Lawrence, who has often been linked to him. 

Her first encounter with who she believes was the jailed taxi driver happened in Tinsley Marina in Sheffield, the same year that Lawrence went missing, the newspaper reports.

Then she says she saw him again at the White Horse beauty spot in North Yorkshire years later. 

After telling him she worked at a gardening centre in Pickering, she alleges he showed up there at least three times, leading to her colleagues there branding him her 'stalker'.

Halliwell, 58, is currently serving a life sentence behind bars after pleading guilty to the murder of Sian O’Callaghan, 22, in 2011.

He also admitted murdering Becky Godden-Edwards, 20, in January 2003, but the case was dropped in court.

But former case detective Steve Fulcher believes that Halliwell had more victims, referencing the discovery of 60 'trophy items' at a Wiltshire lake as evidence, and he isn't alone.

Former police intelligence officer Chris Clark and Bethan Truema, the authors of a new book called ‘The New Millennium Serial Killer’, are convinced he has killed many more too. 

They uncovered this witness placing Halliwell in Sheffield, near Claudia Lawrence at the time of her disappearance.

The woman who spoke to the Mirror told them the fishing lakes searched by North Yorkshire police last year are close to where she first saw the mystery man who she thinks is Halliwell.

“He was staying on a canal boat doing some fishing. He said it wasn’t his. He was renting this one,” she said.

“I am sure I saw this same man again when we were out walking at the White Horse near Thirsk. It was around March 2011 just before Halliwell was arrested.

“He turned round to talk to me and asked me where I worked and I stupidly told him."

Three days after this, she claims that Halliwell turned up at the garden centre multiple times.

“People at work started saying ‘your stalker here’s again!’ One time the manager had a word with him,” she said.

“He came and bought things at the shop including a blue rope.

“I was trying to upsell and said ‘you need scissors’ and he said ‘I’ve got this’ and he showed me a knife in a sheath, it was like a double-sided fishing knife.

“He also spoke to me about putting his card on the staff notice board. I read it and it said ‘Christopher' on it and he said ‘call me Chris’. “

“It’s his eyes, they look through you like glass. They are very disturbing. I’ve got goose pimples just thinking about it now,” she said.

She added that Halliwell told her he was thinking of relocating to the area and was touting for work as a taxi driver. She also alleged that he knew the universities in the area and specifically mentioned York to her. 

She said she contacted North Yorkshire Police in 2020 about it but felt they dismissed it.

Claudia Lawrence was last seen and heard from on March 18, 2009. She was employed as a chef at the University of York's Goodricke College at the time of her disappearance

North Yorkshire police force has previously been asked about potential links between Claudia’s disappearance and Halliwell but has said before: "There are no known links between Halliwell and the Claudia Lawrence case.”
