A mother of three who worked as a prostitute was unlawfully killed, an inquest has ruled.
Michelle Bettles was found strangled to death in March 2002.
Michelle Bettles, 22, of Dereham Road in Norwich, was found dead in March 2002 in woods near Scarning. No-one has been charged over her death.
Coroner William Armstrong said he hoped the verdict would allow Michelle's parents' grieving process to move on.
Her father, John Bettles, said: "It's just a chapter that's closed. Obviously there's other chapters still open."
He added: "I believe that one day somebody is going to be punished and hopefully I'll be there to see it. People who say 'Forgive' - no way."
'Catch her killer'
Her mother, who does not wish to be named, said: "The only thing that's going to stop my grief is if they catch her killer - that's basically all it is."
Police said Ms Bettles was last seen by her flatmate on 28 March 2002, having left the flat to meet with a regular client at 2100.
Evidence read out by Mr Armstrong at the inquest revealed that appointment was never kept.
After her body was discovered, police launched an inquiry which lasted over the course of 18 months and involved 30 officers and more than 1,700 witness statements.
