Peterborough ditch deaths: Fresh witness appeal
Detectives investigating a triple murder in Cambridgeshire have appealed for information about the last known movements of two of the victims.
The bodies of Lukasz Slaboszewski, 31, and John Chapman, 56, were found in a ditch at Thorney Dyke on 3 April.
Police said it was "critical" to establish when they were placed there.
Their deaths have been linked to that of Kevin Lee, 48, who was found in a ditch in Newborough on 30 March. All three had been stabbed to death.
The men were all from the Peterborough area.
Det Insp Martin Brunning, who is leading the investigation for Cambridgeshire Police, said: "Obviously we know when the bodies were found but we are still trying to build a picture of when both men went missing and, as importantly, when they were placed in Thorney Dyke.
"I would urge people to look at their photographs and try to remember if they have seen them in the city over the past few weeks."
He said Mr Slaboszewski had been living around the Lincoln Road area of Peterborough.
Mr Chapman lived in Orton Goldhay but often visited the Bifield area. He was last seen on 29 March.
Six people have been arrested in connection with the murders.
A 36-year-old man charged with perverting the course of justice appeared at Peterborough Crown Court on Wednesday. He was remanded in custody and will appear before magistrates again on 20 June.
A 30-year-old woman arrested last week, and a 55-year-old man arrested on Wednesday remain in custody.
A 47-year-old man arrested in Hereford last week, and questioned about the murders over the weekend, has been released pending further enquiries.
Two men, aged 23 and 32, are currently on bail.
