MASS DNA profiling of potentially thousands of local men will begin today in the hunt to find out who killed a grandmother.
Sussex Police have set up a base at the Millstream Hotel in Bosham, the village where 55-year-old artist Valerie Graves was bludgeoned to death on December 29, 2013.
All local men aged 17 and over are being asked to voluntarily give samples of their DNA.
Mrs Graves was house-sitting for friends in Smugglers Lane, with her family, when she was brutally killed with a hammer.
The screening takes place between 10am and 8pm from today until January 29, and from February 2 to 7 and February 10 to 15. The hotel is in Bosham Lane.
