New images released by detectives investigating Anita Rose's suspected murder show the jacket and phone case that have gone missing.
Ms Rose left her house at about 5am on Wednesday, July 24 to take her dog for a walk in Brantham.
At about 6.25am, a member of public found her lying on a track road near the sewage works and railway line, off Rectory Lane, unconscious. An ambulance was called.
Suffolk police officers were then called by the East of England Ambulance Service shortly after 8am.
She was taken to Addenbrooke’s Hospital having sustained a serious head injury, where she died four days later on Sunday, July 28.
Detectives have now released replicated images of Ms Rose's pink jacket that she was wearing at the time of the attack.
They have confirmed that the missing waterproof pink zip-up jacket is from Regatta.
It is from the autumn/winter 2017 range and is a Calderdale II in Duchess Dark Cerise, which is no longer produced.
While officers had previously located and recovered Ms Rose's mobile phone – an Apple iPhone – they are now also appealing to find her missing phone case.
It is described as a black wallet-style quilted case with a gold crown and stud detail.
Detective Superintendent Mike Brown said: “This update has come from continued work alongside Anita’s family who have assisted us in identifying the make and model of the jacket as well as providing us with an image of Anita’s phone case.
“We continue to believe these missing items could hold key information or evidence to the investigation and ask anyone with any information to come forward and speak with us.
“I would like to thank Anita’s family for their continued support throughout this investigation, their co-operation has been integral to this case.”
Police enquiries continue to take place, including forensic work, searches, house-to-house enquiries and CCTV analysis.
Three people have been arrested so far in connection with the attack - including two on suspicion of murder - but they have each been released on bail.
Specialist officers are supporting Ms Rose's family and keeping them updated on the investigation.
Anyone with information that may assist with the inquiry is urged to contact Suffolk police by quoting 37/41580/24.
