A man has been charged with the murder and rape of student Libby Squire.
The 21-year-old, from High Wycombe, Buckinghamshire, disappeared after a night out in Hull on 1 February and her body was found seven weeks later.
Pawel Relowicz, 25, of Raglan Street, Hull, is due to appear before Hull Magistrates’ Court on 30 October.
The Crown Prosecution Service said the charges came after a lengthy and complex investigation by Humberside Police.
Chief Crown Prosecutor Gerry Wareham said Ms Squire’s family had been informed of the development.
“This decision was made following a careful review of all the evidence presented to us by Humberside Police as a result of their lengthy and complex investigation,” he said.
“Criminal proceedings against Mr Relowicz are now active and he has a right to a fair trial.”
Ms Squire was last seen alive just after midnight on 1 February at the junction of Beverley Road and Haworth Street, near her student accommodation on Wellesley Avenue, Hull.
Her body was discovered in the Humber estuary, close to Spurn Point, on 20 March following extensive searches involving hundreds of police officers, specialist divers, dog handlers and the public.
It was released to her family at the end of August.
Hundreds of people attended the philosophy student’s funeral last month.
