Police in north Wales have been given more time to question a 47-year-old man over the murder of an 89-year-old widow.
Florence Habesch was found at her home in Rhyl, Denbighshire, early on Tuesday.
A post-mortem examination revealed she died from a "blunt force" head injury. An inquest has been opened and adjourned to a later date.
Officers have an extra 36 hours to quiz the man, arrested in Wolverhampton.
North Wales Police say the man had a "known association" with Mrs Habesch.
Det Chief Insp Steve Williams, of North Wales Police, said: "We can now confirm that there was a known association between the victim and the male arrested.
"Mrs Habesch's family are being supported by trained officers."
The inquest was opened by John Gittins, deputy coroner for north east Wales.
He adjourned the hearing after hearing evidence of identification and details of the post-mortem examination carried out at Glan Clwyd hospital, Bodelwyddan, by a Home Office pathologist.
Police believe Mrs Habesch may have been killed on Sunday, and have appealed for any witnesses to come forward.
Their inquiries are continuing in the area.
Anyone who may have been in Grange Road on Sunday, and noticed anything suspicious, has been asked to call 101 (if in Wales), 0845 6071001 (Welsh language line), or 0845 6071002 (English).
