A man has been charged with the murder of Catherine Henry in County Louth last month.
Luke Donnelly, 26, of no fixed abode, was arrested on Thursday in relation to the fatal assault.
He appeared at a special sitting of Dundalk District Court overnight and was remanded in custody to Cloverhill Prison in Dublin.
He will appear before the court again, via video link, next Wednesday.
The body of 62-year-old Catherine Henry was found in her home on Bridge Street in Dundalk last Wednesday May 24th.
She had been assaulted and a post-mortem examination was carried out to determine the cause of her death.
The house underwent a full technical examination which Gardaí hope has yielded forensic evidence that will help to link the killer to the crime.
Gardaí have also gathered footage from local CCTV systems as they seek to establish who called to the property in the period before Ms Henry was attacked.
