An 89-year-old woman, beaten by an intruder, died of an illness related to head injuries, an inquest has heard.
Police do not have a motive for the attack
Olga Turner was found by her daughter Pam Price after being left unconscious at her home in Great Barr, Birmingham, on 3 October.
She died in hospital 11 days later and police started a murder inquiry.
The inquest at Birmingham Coroner's Court heard Mrs Turner died of bronchopneumonia. The hearing was opened and adjourned on Wednesday.
Mrs Price made a public appeal on Tuesday for help to find her mother's killer.
Det Ch Insp Chris Pretty said that nothing was taken in the incident and police do not have a motive for the attack.
The inquest was adjourned to a date yet to be fixed, but assistant deputy coroner for Birmingham, Michael Snell, said the case was likely to be reviewed in a month's time.
