THE SUM of £20,000 is now being offered in the hope to catch the killer of Valerie Graves.
The 55-year-old, from Bracklesham Bay, was found dead by her family in the morning on December 30, as they were house sitting in Bosham.
Originally, Sussex Police offered a £10,000 reward for information leading to the capture and conviction of her killer.
Now, national charity Crimestoppers is also putting forward £10,000.
Angela Hollinshead, Crimestoppers’ area manager for Sussex, said: “Valerie’s murder was extremely brutal and her family has been devastated by her death.
“It is hoped that, by increasing the reward, this may assist in convincing someone to come forward and provide us with the critical information that may solve this crime.”
Detective Superintendent Nick May from the Surrey and Sussex Major Crime Team, said: “We are appealing to anyone who has any information or knows the person who has done this.
“You may have your own concerns or suspicions about this person already but for your own reasons have not yet come forward.
“Let me reassure you that we can support you whatever your concerns but this person must be caught.”
Anyone with information on Valerie’s murder should contact Crimestoppers anonymously on 0800 555 111 or through an anonymous online form at www.crimestoppers-uk.org.
There is also a dedicated website set up with information to catch the murderer at www.valeriegravesmurder.com.
