A jury at Tullamore Circuit Criminal Court has found two people not guilty of the manslaughter of a 20-year-old man in Co Westmeath.
However, Jessica Hughes, 21, of Greenfield Heights, Rathwire, Killucan, Co Westmeath, and Patrick Daly, 24, of Mulphedder, Clonard, Co Meath were found guilty of assault.
Andrew Dolan died in hospital on 1 January 2012 following an assault at Pearse Street, Mullingar on 23 December 2011.
The biomedical science student was from Carrick-on-Shannon in Co Leitrim.
Mr Dolan was on the way home from a party when he was repeatedly struck in the head outside a chip shop.
The student did nothing to provoke the attack and pleaded with Hughes, Daly and another accused Patrick Farrell not to hit him.
He was struck again, fell to the ground, lost consciousness and died nine days later in Beaumont Hospital in Dublin.
Farrell has already pleaded guilty to killing Mr Dolan.
