A 56-year-old rapist has been jailed for 15 years after a brutal attack on a pregnant prostitute which left her for dead 18 years ago.
Peter John Carroll of Barnsbury Avenue, Aylesbury, then aged 38, raped and attempted to strangle the 20-year-old victim in his car after earlier meeting her in a pub in Norfolk.
She was left unconscious by Carroll before driving away from the scene.
He had previously been found guilty of rape and grevious bodily harm with intent at Norwich Crown Court following a cold case review by police.
During the attack, the victim, who was four months’ pregnant, scratched Carroll’s face, leaving crucial forensic evidence in her fingernails.
At the time it was not possible to extract a DNA profile from the samples but following advances in technology, a full DNA profile was obtained resulting in a match to Carroll.
Detective Inspector Marie James of the Joint MIT said: “This was a violent attack on a woman who was left with serious injuries to her head, neck and body.
“During the attack the victim fought back and in the process scratched Carroll’s face which was to prove crucial to this conviction.”
Carroll was arrested by detectives from the Joint MIT at his home in Aylesbury on the afternoon of Wednesday, December 18 2013.
During police interviews he denied all responsibility for the attack despite the forensic evidence.
He did admit visiting Norwich on occasions in his role as an engineer for an electrical goods company.
The following day Carroll was subsequently charged with attempted murder and rape.
Detective Inspector James added: “We hope that such a case proves how crucial forensic evidence can help secure a successful conviction no matter how long ago the offence took place.
“This was a horrific assault on a woman who has had to live with the consequences for nearly 18 years.
“It has taken an enormous amount of courage for the victim to stand up in court and give evidence and we would like to commend her for the bravery she has shown.
“Such a case also shows the passing of time should not stand in the way of justice for victims who can be reassured we will do all we can to bring offenders before the courts.”
