Officers investigating the brutal murder of a grandmother have launched a dedicated website in a bid to catch her killer.

Valerie Graves, 55, was bludgeoned to death with a claw hammer between 10pm on December 29 and 10am the following morning last year.

She was house sitting with three others at a property in Smugglers Lane, Bosham, at the time.

A post-mortem examination revealed she suffered significant head and facial injuries.

The website, which was launched today by Sussex Police, includes all the details currently known about her death along with pictures of evidence including the suspected murder weapon.

The claw hammer was found later in nearby Hoe Lane at the entrance to the driveway of Hart’s Farm.

The victim had recently moved to Sussex from Scotland. Over the Christmas period she, along with her mother, sister and sister’s partner, were house-sitting for a friend.

On the morning of December 30 she was found bludgeoned to death in a downstairs bedroom.

A patio door, leading directly from the bedroom outside to the rear of the house was found to be insecure.

Detective Superintendent Nick May, of Surrey and Sussex Major Crime Team, said: "It is seven months since Valerie was brutally murdered while house sitting in Bosham.

"We continue to have a significant number of officers and staff working on the investigation. This inquiry remains a priority for the force.

"We are determined to get justice for Valerie and her family and this case will remain open until we do so.”

He added: “"This new website should keep the investigation in the public's mind as well as continuing to appeal for information. The website offers different ways for the public to contact us and we are offering a £10,000 reward for information which leads to the arrest and conviction of the killer."

The murder was also subject to a feature on Crimewatch earlier this year.

Anyone with information should contact Sussex Police on 101 quoting Operation Ensign or visit www.valeriegravesmurder.com.

The website is also available in 80 languages.
