Mother wants teen killers to feel her pain

When a gang of teenagers who called themselves the "Wakeley Boys" set upon Eden Delir at a Halloween party, they didn't stop bashing him until he managed to run away.

Less than a week later the 17-year-old died. Now his mother says she wants his murderers to feel the pain she does.

The 20-year-old men, who were 15 and 16 at the time, were part of a group of six teenagers who knocked Eden Delir to the ground with a single punch.

They then hit him with a metal pole and smashed a bottle over his head before kicking, punching and stomping on him at Bossley Park in Sydney's west on Halloween in 2010.

The trio, who cannot be named, were found guilty last year of his murder after a jury trial.

Crown Prosecutor Paul Leask told a Supreme Court sentence hearing on Friday the group, who nicknamed themselves the "Wakeley Boys" called their victim over to them before attacking him.

The violence "did not stop until the chasing of Eden Delir", he said.

In a hearing last week, Eden's mother Dorothy Delir spoke directly to her son's attackers.

"I wish your denial to turn to guilt, and for you and your loved ones to live the rest of your shameful life with that guilt," she cried while giving her victim impact statement.

"The meaning of happiness died within us."

"I wish upon them and their loved ones the pain they have caused us."

The crown said one of the trio hit Eden in the head with a metal pole.

Telephone intercepts after the murder recorded him telling his older brother that he'd done "something bad" and someone had died during a fight at "Bossley".

"Yeah we just hit him and he fell," he said.

Two other boys, including the one who glassed Eden and another accused of previously setting him up to be robbed were convicted of manslaughter and sentenced to a maximum 10 years jail last year.

Another, also convicted of manslaughter, was sentenced to a maximum five years and 11 months.

The trio will face further sentence hearings on March 27.
