Garda investigations are continuing into the death of a 30-year-old Polish man in Tullamore, Co Offaly, yesterday.
They have interviewed the deceased man's wife and a friend and say they are not looking for anyone else.
Yesterday, gardaí were called to a house on Kilbride Street in Tullamore. When they arrived they found two Polish men, both with stab wounds, a woman and a three-year-old boy.
Grezegorz Guzik, who was the husband of the woman, was rushed to the Midlands Regional Hospital in Tullamore but died a short time later.
A post mortem examination on his remains was carried out by Deputy State Pathologist Dr Michael Curtis.
That concluded last night but gardaí say they are not releasing the results for operational reasons.
The other man and the woman were interviewed by gardaí but have not been charged. Gardaí say the two have been helpful during the investigation.
It is believed the incident started before 7am yesterday morning when the woman and her friend returned to the house to collect her child.
There was a row inside, and one theory gardaí are examining closely is that the fatal wounds Mr Guzik suffered were not caused by anyone else in the house.
