A 52-year-old man has been found guilty of raping and murdering barmaid India Chipchase, 20, who was found dead under a plastic sheet at a house in Northampton on 31 January.
Edward Tenniswood, described as an "oddball", claimed he had accidentally throttled her during consensual sex but a jury of Birmingham crown court found he had murdered her.
He has been sentenced to life in prison and will serve a minimum term of 30 years.
Police said a forensic postmortem carried out by a Home Office pathologist found that Chipchase died “as a result of pressure to the neck”.
Tenniswood had taken Chipchase back to a flat in a taxi after meeting her outside a nightclub in Northampton. He was reported to have been overheard telling her he would get her home safe.
The jury heard how he "cuddled up" to her lifeless body before leaving the house for a kebab, the BBC reported.
He was then arrested at a hotel bar, where he had been drinking for 22 hours.
“India was a young woman at the start of her life, who should have been able to enjoy a night out with friends and return home without coming to any harm," said Detective Chief Inspector Steve Woliter from the East Midlands Special Operational Unit, which led the investigation.
“It is clear that Tenniswood targeted India at a point when she was most vulnerable and unable to defend herself – the actions of the worst kind of predator.
"My lasting hope is that India’s family is able to take some kind of solace in the fact that Tenniswood will not be able to prey on any other young women who are innocently going about their lives.”
