A sick killer has been jailed for life for abducting and murdering his ex-girlfriend as she cycled to work.
Evil Andrew Pearson laid in wait for Natalie Harker before grabbing her and dragging her to a secluded tent in nearby woodland.
He then had sex with her as she lay unconscious or dying, Teesside Live reports.
Pearson had denied the murder and abduction but he was convicted following a three-week trial at Teesside Crown Court.
Judge Stephen Ashurst today jailed him for life with a minimum term of 23 years and 320 days.
The judge said: "You took her lifeless body into the tent, stripped her of her clothes which you then folded and took into another part of the tent.
"Whether she was still breathing or not, you thought only of yourself, not just in the shock of the moment, but for hour after hour."
Natalie, 30, had ended their 18-month relationship about two months before she was murdered on October 9 last year.
A jury heard she had been concerned about Pearson, 45, of Colburn, North Yorkshire, and she confided in friends and colleagues about being stalked and harassed by him.
The judge said Natalie did not take advice to contact the police, saying: "I tend to take the view that's likely to be because Natalie thought the best of people. She was trusting and naive."
The victim was reported missing when she failed to turn up to her cleaning job at a health centre.
North Yorkshire Police received a call from Pearson's mother who said her son had told her the pair met up and had been walking together at around 4.30am when Natalie had accidentally slipped and fallen into a river, pulling him in too.
She said Pearson told her he pulled Natalie from the water and started CPR before taking her to his tent and continuing to do so.
He told his mum he must have passed out and when he woke up following a phone call, Natalie appeared to be dead. Pearson led officers to the tent and was arrested soon after on suspicion of murdering Natalie.
Chilling evidence emerged which resulted in Pearson being re-arrested on October 15 and charged with his ex-girlfriend's kidnap and murder.
Detectives discovered in the days leading up to Natalie's murder, Pearson had used all of his Universal Credit to purchase camping equipment, knives, gaffer tape and supplies of food which were later found in the tent.
A text message was written, sent, delivered and then deleted to a friend on the day of Natalie's death saying: "Goodbye, I've killed Natalie I'm going to hand myself in."
There were significant injuries which suggest she was violently drowned. Scientific findings indicate sexual intercourse took place when she was either unconscious or dead.
Detective Inspector Steve Menzies said: "Evidence proved beyond any doubt that Pearson had planned the kidnap and murder of Natalie, and the level of planning was extremely calculated and chilling.
"No outcome at court can bring Natalie back and our hearts continue to go out to them.
"As for Pearson, it says everything about him as an individual that he refused to answer any questions throughout the police investigation.
“He refused to explain in his own words about what happened to Natalie and sat emotionless in the interviews with my specialist officers.
“Only Pearson knows what motivated him to kidnap and murder her. Only he knows if it was through jealously or anger in refusing to believe that his relationship with Natalie was over for good.
“We now know that he had been following her and turning up at her work during the early hours of the morning. He had tried to discredit her character, including via social media, making out that he had been wronged by Natalie.
“In actual fact, he was infatuated with her and refused to accept that she had ended their relationship."
