murder of five women who worked as sex workers
The Ipswich serial murders took place between 30 October and 10 December 2006, during which time the bodies of five murdered women were discovered at different locations near Ipswich, Suffolk, England. All the victims were women who worked as prostitutes in the Ipswich area. Their bodies were discovered naked, but there were no signs of sexual assault. Two of the victims, Anneli Alderton and Paula Clennell, were confirmed to have been killed by asphyxiation. A cause of death for the other victims, Gemma Adams, Tania Nicol and Annette Nicholls, was not established.

Suffolk Police linked the killings and launched a murder investigation codenamed Operation Sumac. Due to the size of the investigation police officers were drafted from several other police forces. Two arrests were made in connection with the murders. The first suspect, who was never officially named by police, was released without charge. Forklift truck driver Steven Gerald James Wright, then aged 48, was arrested on suspicion of murder on 19 December 2006 and charged with the murders of all five women on 21 December
