The third prostitute found dead near Ipswich was murdered by asphyxiation and "probably strangled", Suffolk police said today.
Police named her as 24-year-old Anneli Alderton, of Colchester, Essex. The cause of her death was revealed after the completion of a post-mortem examination by a Home Office pathologist last night.

Post-mortems on Tania Nicol, 19, and 25-year-old Gemma Adams - the women whose bodies were the first two to be found - were inconclusive, and further tests were being carried out.
Detective Chief Superintendent Stewart Gull told a news conference there were no signs that either had died of asphyxiation, saying there appeared "to be different causes of death".
He said officers were investigating the possibility that the three women had been poisoned. "We are doing toxicology tests, along with a number of other clinical and scientific analyses following the post-mortems, and we will do the same with the latest victim," he added.
Mr Gull said the three women could have been killed by the same person, but stressed he was not using the phrase "serial killer". "I have emphasised throughout we are not necessarily looking for one killer - there may be more," he said. "We have got to keep an open mind."
He added it was possible that DNA from the killer or killers could be retrieved from Ms Alderton's body.
In a direct appeal to the killer or killers, he said: "Make contact with Suffolk police. Clearly you have a significant problem. Give me a call and we can deal with this. My appeal is simple - give yourself up."
Mr Gull told the press conference that the first two murders had been linked, but the killing of Ms Alderton had not been formally linked to them. However, he said this could change.
"It is too early ... Anneli Alderton has only just undergone a post-mortem," he said. "Clearly, there are similarities ... these are women who were working as prostitutes in Ipswich."
He said Suffolk police continued to have "grave concerns" for two missing women who also worked in the "tightly knit" community of sex workers in the town - Paula Clennell, aged 24, and 29-year-old Annette Nicholls.
The pair have not contacted police despite urgent appeals for them to do so. "There have been other girls reported as missing who have subsequently been found," Mr Gull said. "I hope Paula and Annette are just lying low for whatever reason."
Detectives today formally announced a murder investigation into Ms Alderton's death. Her body was found on Sunday afternoon in a woodland close to Nacton, near Ipswich, after a passing motorist saw a naked body.

Mr Gull said the killer or killers had probably moved the body to the area, but it was not known at this stage whether she had been sexually assaulted.
She had caught the 5.53pm train from Harwich to Colchester on December 3, but there were no known sightings of her after that. Another passing motorist could have seen her body at 10.30am on Thursday, but mistakenly believed it to be an abandoned mannequin.
He reiterated that there were no signs of significant trauma to the bodies of either Ms Nicol or Ms Adams, and said neither appeared to have been subjected to a serious sexual assault.
Mr Gull told the press conference that the two women definitely knew each other, adding it was likely that Ms Alderton knew the other two murder victims.
Suffolk police have received more than 450 calls from the public about the deaths, with around 25 being made on a dedicated line set up for prostitutes working in the county.
"I have been very pleased with the response to our appeal so far," Mr Gull said. "I would ask anyone with information to come forward as a matter of urgency."
Suffolk police is a relatively small force, and questions have been asked about whether it is able to cope with an inquiry of this scale. Mr Gull said more than 100 staff were working on the murders, with extra officers being drafted in from Essex today.
He added that police were looking at "a number of interesting individuals", and that officers were carrying out searches in different parts of Suffolk. However, he stressed the killer or killers could be from outside the county.
Mr Gull appealed to men who had recently been clients of the women to get in touch with officers, and also appealed to prostitutes to contact police. "The perpetrator may be a client, he may be a kerb crawler," he said.
Police have warned all women to stay away from the red light area of Ipswich, and Mr Gull urged women in the town and its surrounding areas to be vigilant.
"Do not go out alone, go out in company - make sure you know where you are going and, if possible, give someone a contact number," he said. "Any single woman could potentially be in danger."
