Timeline: The prostitute killings
Police are investigating the murder of three prostitutes sparking fears a serial killer may be prowling the red light area of Ipswich.

Here are some of the key events in the police investigation.

Det Supt Andy Henwood says there were "obvious similarities" between the two deaths.
10 DECEMBER
Police announce that the body of a third prostitute has been found raising further fears that a serial killer is targeting women in the area.
Officers are called to Nacton, near Ipswich, at 1520 GMT after a member of the public discovers the woman's body in woodland.
Police say the body is of a woman in her 20s.
Detectives say it is too early to say whether the third death is linked to the murders of Miss Adams and Miss Nicol.

Police say they are concerned for two other missing women.
Paula Clennell, aged 24, has not been seen since late on Saturday, and Annette Nicholls, aged 29, went missing on December 4.
Assistant Chief Constable Jacqui Cheer warns prostitutes to "stay off the streets" for their own safety.
Police describe the discovery of the third body as a "deeply disturbing development" and that while they are unable to formally link the discovery of the body at Nacton with the two murders, "the facts speak for themselves".
12 DECEMBER
Police discover two more bodies near the village of Levington, five miles south of Ipswich.
Det Ch Supt Stewart Gull said: "I have to fear the worst. Sadly I fear these may be the bodies of Paula Clennell and Annette Nicholls."
Police investigating the murders of the three prostitutes near Ipswich release the name of the third victim, Anneli Alderton, 24, and say she was strangled.
Tests are being carried out to see if she was sexually assaulted.
13 DECEMBER
Police begin a detailed forensic examination of the scene where the bodies of the two latest victims were found.
Det Ch Supt Stewart Gull reveals at a news conference that 2,199 telephone calls were received in the incident room on 12 December.
He says the inquiry is now the largest ever seen in the area, and more than thirty officers have been drafted in from other forces and more are expected to join the hunt.
It also emerges that Paula Clennell had given an interview to ITV News on 5 December, in which she said that despite the dangers, she was prepared to go back onto the streets.
