A post mortem is due to be carried out today on the body of a man who was discovered with severe head injuries at his home in Co Kerry two days ago.
The man died in hospital overnight. He was found in the kitchen of his house on Upper Rock Street in Tralee on Monday morning.
It is unclear whether the dead man received the injuries as a result of a fall or whether he was assaulted.
Gardaí say they are keeping an open mind in the investigation.
