Murdered Angelika Dries-Jenkins suffered head injuries
A Pembrokeshire woman who was murdered in her home died from "substantial" head injuries, a post-mortem examination has confirmed.
Angelika Dries-Jenkins' body was found on Friday in Providence Hill, Narberth, but police said she could have been killed any time last week.
Police have not confirmed what the murder weapon was but asked for help to catch the 66-year-old's killer.
They want to know how her Skoda Fabia car ended up in Haverfordwest.
In a statement on Tuesday, Dyfed-Powys Police said:"Following a post mortem examination conducted by a Home Office pathologist, we can confirm that Angelika had sustained substantial head injuries.
The statement continued: "There does not appear to have been a sexual motive.
"We would like to thank the public for all their assistance so far - but are continuing to appeal for any further information or witnesses to come forward by calling 101."
An inquest into the death of Ms Dries-Jenkins was opened by the Pembrokeshire coroner on Tuesday before being adjourned to a date to be fixed pending police enquiries.
On Monday, Ms Dries-Jenkins' family appealed through police for help in tracing her killer.
In a statement, her children said: "Over the last two years, she fought against and overcame serious illness. She wanted to live.
"The violent nature of our mother's death is in all too horrible a contrast with the way in which she lived her life."
They asked people in the Narberth community to assist the police investigation.
"The person or people responsible for killing our mother must not be sheltered or protected but prevented from doing anything like this to any other person or family ever again," her children said.
One focus of the police investigation surrounds Ms Dries-Jenkins' champagne-coloured Skoda Fabia.
The car, registration GP05 LNY, was taken from the pensioner' s home around last Tuesday.
It was found in St Thomas Green, Haverfordwest, at about 1300 BST on Saturday. Police are not sure how long it had been there.
Det Supt Pam Kelly said on Monday: "We know that vehicle has travelled in the Narberth and Haverfordwest area during the past week.
"I would like people to help me because I need to know who has been driving that vehicle and who has been in that vehicle."
Anyone with concerns, or any information that might help the investigation, can contact Dyfed-Powys Police on 101.
