Two people arrested as part of the police’s wider investigation into the murders of a Cambridgeshire father and son remain under investigation.  

Gary Dunmore, and his son Josh, were both shot dead last year at their respective homes in Sutton, near Ely, and Bluntisham, near St Ives.  

Widower Stephen Alderton – who was Josh’s ex-father-in-law – was initially sentenced to life in prison with a minimum term of 25 years, minus the time already served, for the murders. 

The Court of Appeal increased that sentence in January to life, with a minimum of 30 years, minus the time already served. 

As part of the wider police investigation, a 33-year-old woman and a 28-year-old man, both from Mildenhall, Suffolk, were also arrested last year on suspicion of conspiracy to murder as part of the wider police investigation. 

They were re-bailed twice until last Friday (June 7) and Cambridgeshire Police have now confirmed they have been released under investigation.  

This means police are continuing to investigate the alleged criminal offence.  

Unlike being placed on bail, there are no conditions the suspects must follow and no time limits set by police for the investigation.  

Last June, a 51-year-old man and a 22-year-old woman, both from Bristol, were also arrested on suspicion of encouraging or assisting crime and were released under investigation.      

Alderton, of no fixed abode, shot Josh, then 32, in his home in Meridian Close, Bluntisham, at around 9pm on March 29, 2023.     

He then travelled to Sutton where she shot Gary, then 57, at his home in The Row.
