A 34-year-old man from Italy who had been living in the victim's home as a lodger allegedly admitted to killing his landlord Sunday and then eating his heart, the Irish Independent reported.
Saverio Bellante was charged Monday with killing Tom O'Gorman, The Guardian reported Monday.
The Irish Independent said police found O'Gorman after Bellante called emergency services, allegedly telling the operator he had killed a man.
Once police arrived, Bellante allegedly said he killed O'Gorman over a chess move, then ate his heart, the Irish Independent said.
The suspect, arrested at the scene, later told police the victim asked him to leave the house after the confrontation and he agreed to do so. Police said the victim was stabbed with a kitchen knife and beaten with a dumbbell.
"The victim's heart was intact but the PM [post mortem] confirms that a lung was removed from the body and has not been located," a source told the Irish Independent.
