Man who killed baby son was known risk

A SADISTIC father battered and burned his son to death because he was jealous of the attention the boy's mother gave the baby.

As Paul O'Neil began a minimum 22-year jail term for murdering his son Aaron, it emerged that social services and health staff had known he posed a risk to children but did little to intervene.

Social services had looked into the jobless father-of-six's violent past in May 2004, nine months before he killed his three-month-old son.
