Steve Wright has been questioned in prison about a number of unsolved cases, but police say he is not currently a suspect in any of them. Suffolk Police told the BBC that officers consider the possibility of his involvement when reviewing cold cases, and have used DNA evidence to eliminate him from inquiries where it is available.

The force began considering possible links to other disappearances and killings after Wright admitted to kidnapping and murdering 17-year-old Victoria Hall in September 1999. He received a further life sentence for her killing in February. Hall disappeared after leaving a nightclub in Felixstowe and her body was found five days later in a ditch in Creeting St Peter, about 25 miles away.

Wright was due to stand trial at the Old Bailey for Hall’s murder and kidnapping, as well as the attempted kidnapping of 22-year-old Emily Doherty. He unexpectedly pleaded guilty to Hall’s murder. Police said they would not identify the cases officers asked him about.

Wright, 68, is also serving a whole-life sentence for murdering five women in Ipswich between October and December 2006. He was convicted in 2008 of killing Tania Nicol, Gemma Adams, Anneli Alderton, Paula Clennell and Annette Nicholls. Police said he was not questioned again about those murders after his guilty plea in Hall’s case.

Criminologist David Wilson has suggested Wright may disclose possible links to other disappearances, including the cases of Kellie Pratt, who was last seen in Norwich in 2000, and Amanda Duncan, who went missing in Ipswich in 1993.
