28 February: Joanne Dennehy will never be released from jail after receiving a whole life prison term


Joanne Dennehy’s terrifying killing spree started in March 2013:

Dennehy, of Bifield, Peterborough, murdered Lukasz Slaboszewski on 19 March 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 3 April.

Stretch, (47), of Riseholme, Peterborough, was convicted of helping 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 29 March at Bifield, Peterborough.

Stretch and Layton, (37), of Bifield, 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 29 March. 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 30 March, 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 1 April.

By 2 April, 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 (3 April).
