Victoria Hall: New information about 1999 teen murder
Witnesses have come forward with new information about the murder and abduction of a teenage girl 20 years ago, police said.
Victoria Hall, 17, from Trimley St Mary in Suffolk, went missing on her way home from a nightclub on 19 September 1999.
Her naked body was discovered in a water-filled ditch five days later but her murderer has never been found.
Victoria's parents said they had "a lot of hope" her killer would be caught.
Her mother Lorinda Hall said the person responsible had taken "a large part of our hearts away".
"They have had 20 years where they should have been feeling guilt and horror about what they've done," she said.
Victoria had been at the Bandbox nightclub in Felixstowe with her friend Gemma Algar on the night she went missing.
The two girls left the club at about 01:00 BST on 19 September and walked the two miles back to Trimley, stopping at a takeaway along the way.
They were 300 yards from Victoria's home when the best friends parted at 02:30 BST.
Gemma heard a scream after but thought nothing of it and a major missing persons inquiry was launched when Victoria did not return home.
Victoria's body was found in Creeting St Peter, near Stowmarket, 25 miles from where she was snatched, on 24 September.
Her father Graham said: "It won't bring Victoria back if we find out who did it but it would give us closure.
"We wonder what happened on that night, why the person decided to do this, why they decided to take her to Creeting and dump her body in water."

Police have released details of items belonging to Victoria for the first time as part of the investigation.
The teenager, who was wearing a black dress and tan jacket, was carrying a black oval-shaped purse and a house key with a fob that said Vicky across the top and Victoria down the sides.
The inner soles of one or both of her shoes had been fixed with sticky tape, Suffolk Police said.
Det Ch Insp Caroline Millar said she would not expand on the new information any further.
She said all the information from the original investigation would be reviewed with "fresh eyes and a new team" and the new lines of inquiry would be treated as "live and active".
She added: "I will take this and exhaust all lines of inquiry."
In 2001, a businessman was cleared of murder following a trial.
