The father of one of the five prostitutes found murdered in Suffolk has appealed for the public to help police catch her killer.
Jim Duell, whose daughter Tania Nicol was found in a brook at Copdock, said she was "loving and sensitive".
Suffolk Police received reports that another woman from Ipswich, who may have worked as a prostitute, was missing, but she was found safe.
Earlier, officers said they were looking at fewer than 50 suspects.
Mr Duell said the dead women were "now at peace", and the killer, he said, could not take away their courage, fortitude and the memories of the victims' families.
Speaking at police headquarters in Martlesham, he said: "We ask for anyone who knows this person or persons to come forward and contact the police even anonymously.
"Tania was a caring, loving, sensitive girl who would never hurt anyone. Unfortunately, drugs took her away into her own secret world."
Meanwhile Essex Police sealed off part of the A120 in Harwich after women's clothing was spotted on a roundabout.
A spokesman said the clothing is likely to be sent to Suffolk for an assessment but this "could take some time".
He added: "The role of Essex Police is to make sure there is no contamination of the scene so the roundabout at the A120 at Parkeston, Harwich is still sealed off but it is expected to be open shortly."
Police hunting the women's killers have confirmed the fifth body found was prostitute Annette Nicholls.
The 29-year-old's body was discovered naked at Levington near Ipswich but a post-mortem examination failed to reveal exactly how she died.
The other four murdered prostitutes are Gemma Adams, 25, Tania Nicol, 19, Anneli Alderton, aged 24 and Paula Clennell, 24.
Detectives had received 1,800 calls from the public in the last 24 hours, on top of the 5,500 already logged.
Det Chief Supt Stewart Gull said: "We are making good progress. We have had a significant response.
"We are looking at a number of interesting people, pursuing a number of interesting lines of inquiry.
"We have got a range of individuals who have been suggested to us. Some are local but some are not. Some are not punters."
He said toxicology tests would take time because the women were "polydrug-users" but he said his message to the people of Ipswich was "don't panic".
Police had linked all five deaths and each had its own specialist team with co-ordination officers working between them.
Suffolk Police are being helped by 26 other forces and 250 officers are working on the five murder inquiries.
"All these resources are committed solely to catching those responsible for the murder of these five vulnerable women," Mr Gull said.
A candlelit service has been held in a church close to where the bodies of two of the women were found.
The Rev Chris Wingfield held the service at St Peter's Church, Copdock, near Ipswich on Friday afternoon.
The Rt Revd Richard Lewis, Bishop of St Edmundsbury and Ipswich, will speak ahead of Ipswich Town's home match with Leeds United on Saturday.
His prayer will be followed by a minute's silence involving players and fans at the team's Portman Road ground.
