DETECTIVES investigating the murder of a grandmother are stepping up the inquiry by going door-to-door asking men to provide DNA samples.
Valerie Graves was brutally murdered in her bedroom in Smugglers Lane, Bosham, on December 30, 2013.
No-one has been charged.
In January and February Sussex Police set up the biggest voluntary mass DNA screening in its history, asking all men aged over 17 who live, work or visit Bosham to provide a DNA sample and a thumbprint to eliminate them from the inquiry.
Of the 2,466 samples, 2,339 men have been eliminated. Although the screening is voluntary officers will be knocking on doors in Bosham next week asking men to volunteer their DNA.
Det Supt Nick May of Surrey and Sussex Major Crime Team said: ‘We want to thank all those men who attended the voluntary sessions in Bosham, Fishbourne and Chichester over the three-week session to give their DNA. The response has been positive.
‘We still need those men who have not come forward to do so. We will be doing house-to-house enquiries and knocking on doors during a week of action from Monday until April 12 asking those who have not given their DNA to consider doing so.
‘If we don’t get a reply we will also be sending out further letters asking them to attend Chichester police station to give their DNA.
‘We have to be tenacious in our efforts to catch the killer. But we do understand that this is an entirely voluntary process and there is no compulsion for anyone to co-operate with us.
‘We simply want to do the best we can for Valerie’s family and for the community in bringing the killer to justice.’
Men who still need to give their DNA can go to Chichester Police Station front office, Kingsham Road, which is open from 9am to 8pm Monday to Saturday or the mobile incident unit, which will be at Tesco Extra in Fishbourne on April 10 and 11, from 10am to 8pm and April 12, 10am to 4pm.
Call 101 and quote Operation Ensign or Crimestoppers on 0800 555111 with information about the murder.
