Dale Creighton died in hospital on January 2nd 2014 – a day after being chased and beaten on suspicion of stealing a mobile phone.
Ms. Justice Deirdre Murphy said his life was “brutally ended” by a group of average young people who decided to take the law into their own hands.
Seven people originally went on trial for his murder, but the charges were dropped after the pleas to lesser offences were accepted by the DPP.
23 year-old Ross Callery of Gortlum Cottages, Brittas, Co. Dublin has been jailed for six years after pleading guilty to manslaughter.
26 year-old Graham Palmer of Park Ave, Portarlington , Co. Laois was jailed for five years after admitting the same offence.
The sentence hearing continues before the Central Criminal Court.
