A woman who was found dead in West Sussex died from "significant head and facial injuries" according to a post mortem examination. Valerie Graves, who was 55, had been house sitting in the property on Smugglers Lane in Bosham when she was killed.
Police are continuing to appeal for witnesses to come forward.
The post mortem has revealed the cause of death but we are still keeping an open mind as to the motive. We are appealing for witnesses who may have seen anyone acting suspiciously or anything unusual in the area from late afternoon on Sunday 29 December to around 10am on Monday 30 December. Please call us if you know anything, no matter how insignificant you might think it is. It could be important to the investigation."
