PRO-LIFE campaigner Tom O'Gorman died as a result of blunt force trauma to the head and stab wounds to the neck and chest, his inquest has heard.
Former journalist Mr O'Gorman (38) was found dead in his home in Beechpark Avenue, Castleknock, on January 12 after gardai were called to the house during the early morning.
Italian man Saverio Bellante (34), the dead man's former lodger, is charged with his murder.
At the opening of Mr O'Gorman's inquest, Dublin Coroner's Court heard that he was identified using DNA sampling from his brother and sister.
The identity was confirmed by Dr Emily Jordan, a forensic scientist at garda headquarters.
The post-mortem was carried out at the Dublin city mortuary by State Pathologist Prof Marie Cassidy.
Coroner Dr Brian Farrell said she has given the preliminary cause of death as "blunt force trauma to the head and a stab wound to the neck and chest".
The dead man's brother, Paul O'Gorman, was present in court.
Det Insp Colm Murphy requested an open-ended adjournment of the inquest pending the completion of criminal proceedings.
Dr Farrell said he was aware of some of the circumstances but could not comment because the matter is before the courts.
Mr Bellante, from Sicily, was arrested and charged with murder shortly after Mr O'Gorman's body was discovered.
At his first hearing at Blanchardstown District Court on January 13, Det Gda Patrick Traynor said the accused replied "I am guilty" after he was charged. He was remanded in custody after that hearing.
