Three people have been jailed for between nine and 10 years each for killing a new-age traveller and dumping his body in a slurry tank.
A Cork man was also jailed for six months for impeding the investigation into the English man's death.
Father-of-two Jason Thomas (39), from Exeter in England, and Scottish mother-of-one Amanda McNab (27) were sentenced to nine years each after pleading guilty to the man- slaughter of Gary Bull on September 23, 2007.
Fermoy, Co Cork native and mother-of-four Una Geaney (45) was found not guilty of murder but guilty of his manslaughter at the Dunmanway, Co Cork, farmhouse she rented with McNab. She was sentenced to 10 years in prison at the Central Criminal Court yesterday.
Joseph Barrett (25) of Drimoleague, Cork, was sentenced to six months after pleading guilty to withholding information.
Gardai found Mr Bull's body on October 11, 2007 in the slurry pit on the farm attached to the women's home.
He died after suffering blunt-force trauma during a weekend-long birthday party that had taken place at the house.
A number of minor rows took place before there was another scuffle between Geaney and Mr Bull. Thomas gave Geaney her own wooden mallet and told her to hit Mr Bull.
She hit him on the legs and handed the mallet back to Thomas, who continued the assault on Mr Bull's head.
The body was dumped in the slurry tank and Thomas headed for England, where he was caught last year.
Mr Bull had distanced himself from his family and moved to Ireland, where he was a heroin addict.
Mr Justice Paul Carney backdated all sentences to the dates each defendant went into custody.
