Following the sentencing of Shahidul Ahmed, the Chief Crown Prosecutor for Thames and Chiltern Crown Prosecution Service (CPS) said he was an "extremely dangerous" man who already had convictions for sexual assault.
We may never know for sure what happened that night, or why Ahmed murdered Rachel, but what we do know is that Ahmed is an extremely dangerous man who was convicted last year of a sexual assault against another young woman.
Had it not been for his arrest for that offence Ahmed may never have been brought to justice for Rachel’s murder. It is thanks to developments in DNA evidence techniques that we are able to secure this conviction today.
Two innocent men were imprisoned as a result of this terrible crime and we hope that this conviction represents closure for them too.
