Detective Chief Inspector Martin Brunning, who led the investigation, said: “Three men were brutally murdered in Peterborough and two men were stabbed in West Mercia – we are pleased today their killer and her willing accomplices are now behind bars.

“Joanne Dennehy is a dangerous individual and will never be released to the public.

“She is a sadistic serial killer with a fearsome personality and carried out these brutal attacks of men who posed no threat to her.

“I am relieved her accomplices will also be facing a substantial period of time behind bars.

“Our thoughts are with those families and the surviving victims who have been affected by these people’s actions.

“Two of the victims will live with what Dennehy has done for the rest of their lives. I hope today’s sentence will provide them with some closure to these devastating events.

“I’d also like to say we are thinking of the Dennehy family who are struggling to come to terms with what Joanne has done and I hope this result means they can also try to move on.”

Stretch, formerly known as Gary Richards, was jailed for life and must serve a minimum of 19 years. He had been convicted of three counts of preventing lawful and decent burial and two attempted murders following a trial at Cambridge Crown Court.

Layton, 37, of Bifield, Orton Goldhay, was sentenced to a total of 14 years. He had been found guilty of two counts of preventing lawful and decent burial and perverting the course of justice following a trial.

Robert Moore, 56, of Belvoir Way, Dogsthorpe, was locked up for three years. He admitted two counts of assisting an offender.

Dennehy, of Bifield, Peterborough, murdered Lukasz Slaboszewski on March 19 at Rolleston Garth, Peterborough. After stabbing the 31-year-old to death, his body was put in a green wheelie bin where it was kept before it was discovered dumped on farmland at Thorney Dyke on April 3. Stretch, 47, of Riseholme, Peterborough, helped her move his body.

The body of John Chapman, 57, was also found at the same time nearby. He had been stabbed to death on March 29 at Bifield, Peterborough.

Stretch and Layton had helped Dennehy remove Mr Chapman’s body from the house and dump it at Thorney Dyke.

Dennehy’s third victim, and the first body to be found, was Kevin Lee, 49, from Fletton, who ran a lettings agency in Peterborough and was the landlord for the Bifield and Rolleston Garth properties.

He was reported missing by his family on March 29. He was last seen buying CDs from HMV in Peterborough before going to meet Dennehy.

His body was found on farmland at Newborough by a dog walker, on March 30, and his Ford Mondeo was later found burned out.

A murder investigation was launched and Dennehy and Stretch were quickly identified as having been involved. A wanted appeal was issued for the pair.

On March 30, Dennehy and Stretch spent the night with Robert Moore at Belvoir Way, Peterborough. Moore later lied to police about their whereabouts and told the pair about developments into the murder investigation.

Dennehy and Stretch left the Peterborough area on March 31. Layton was arrested on April 1.

By April 2, while on the run from police, Dennehy and Stretch committed two burglaries in Herefordshire. They then drove around Hereford looking for people to kill, selecting victims at random.

At about 3.40pm, Dennehy got out of the car being driven by Stretch and stabbed Robin Bereza, 63, who had been walking his dog, on Westfaling Street.

Less than 15 minutes later, having left Mr Bereza for dead, Stretch selected John Rogers, 56, who was walking his dog along a footpath between Golden Post and the Belmont estate. Dennehy stabbed him repeatedly before stealing his dog, Archie.

Stretch and Dennehy were arrested soon after and the green Vauxhall Astra was seized by police. The dog was recovered alive and well.

The bodies of Mr Chapman and Slaboszewski were found the following day.
