'We will forever be heartbroken', says mother of man murdered in Tallaght

The mother of a man shot to death in the front garden of his home by a teenager has said she will never understand why her "gentle giant" of a son was murdered.

Doris O'Neill made a statement during the sentencing hearing for Warren Nolan, 22, who was aged 18 when he shot Alan O'Neill, 35, at Kiltalown Road in Tallaght on May 27, 2015 in an attack that was planned over several days.
