Police investigating a murder have released new CCTV footage showing the victim on the morning she was attacked while walking her dog in Suffolk.
Anita Rose was found unconscious by a cyclist in Brantham on a track road near the sewage works and railway line, off Rectory Lane, on 24 July.
The 57-year-old had left her house at around 5am to walk her springer spaniel dog, Bruce, before being found critically injured at around 6.25am.
She was taken to Addenbrooke’s Hospital, in Cambridge, but died on 28 July.
Suffolk Police has also released two images of a man officers would like to speak to.
He is not believed to be a suspect, but is thought to be a potential witness who “may be able to assist with the inquiry”, police said.
In the footage, police said Ms Rose is seen at the start of her walk at Palfrey Heights at around 5am – and then again around 15 minutes later on Rectory Lane.
She is wearing dark leggings, trainers and a pink jacket, which detectives said is a “discontinued cerise-coloured Regatta Calderdale II jacket”.
Along with the jacket, police said a black phone case – described as quilted with a gold crown and stud detail – and white Samsung Galaxy Buds2 earphones are still missing.
Police have repeated an appeal for people to contact them with any information relating to these items.
Officers said Ms Rose’s dog, which was still with her, was not harmed.
Crimestoppers has offered a £20,000 reward for information that leads to the arrest and conviction of anybody involved in the death of Ms Rose.
‘We continue to investigate all possible motives’
Detective Chief Inspector Matthew Connick said: “It was a light morning and Anita was seen on CCTV wearing a distinctive, brightly coloured jacket during her walk.
“She was not wearing this when she was found injured by the member of public and we do not know why this was removed or where it is now.
“We continue to investigate all possible motives for the attack, and from our enquiries so far there is nothing to suggest that Anita was sexually assaulted.
“We know Anita used an app on her phone that enabled her to track the route she was taking around the village.
“She and Bruce walked in a northeasterly direction from Palfrey Heights, circled the church and walked south of Rectory Lane into the open countryside,” he added.
“She then followed a path along the railway line that runs through Brantham until she turned right towards the top of Newmill Lane.
“Anita followed Newmill Lane down to the river and doubled back to the top of Newmill Lane where she stopped her app at 6.03am, having walked approximately three miles.
“We know from previous walks that this is the same location where Anita has previously stopped the app and we believe she then retraced her steps away from Newmill Lane with the intent to finish her walk via Decoy Pond but was subject to an attack before she was able to reach it.”
