A woman who was arrested on suspicion of murdering a 71-year-old woman in Cheshire has been released.
Agnes Hanrahan was found dead with head injuries at her home in Baguley Avenue, Widnes, by a relative on 8 December last year.
Police said at the time she was not the kind of person to let strangers into her home and may have known her killer.
A 52-year-old woman from Widnes was arrested on Tuesday but released without charge.
