DNA and fibre evidence was presented to the court that linked Wright to the victims.He was found guilty of all five murders on 21 February 2008, and was sentenced the following day to life imprisonment, with a recommendation that he should never be released from prison.Due to the size of the investigation police officers were drafted from several other police forces.
Wright was remanded in custody and his trial began on 14 January 2008 at Ipswich Crown Court.
Wright pleaded not guilty to the charges, although he admitted having sex with all five victims and that he had been patronising prostitutes since the 1980s.
The murders received a large amount of media attention, both nationally and internationally.
The press often compared the murders to those committed by the Yorkshire Ripper, Peter Sutcliffe, who murdered 13 women and attacked seven others (mostly prostitutes) between 19.
Throughout his trial he had stated that he had used professional sex-workers on many occasions, including three of the victims and when his partner began working night shifts and their sex life became almost non-existent, he returned to using professional sex-workers who were based on the nearby streets, procuring a dozen in the final three months of 2006.
Between 30 October and 10 December 2006, Wright murdered five sex-workers in Ipswich.
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.
He was found guilty of all five murders on 21 February 2008.
On the following day, he was sentenced to life imprisonment, and the judge recommended that he should never be released.
On 10 December, a third victim, found by a member of the public in an area of woodland by the A14 road near Nacton, was later identified as 24-year-old Anneli Alderton.
