Scroll down for ITV News' interview with Ronan Kerr's mother
The mother of a policeman murdered in Northern Ireland nearly one year ago said his dissident republican killers have achieved nothing.
Nuala Kerr said she felt sorry for those responsible for the death of her son Ronan, as they would always live with the guilt of taking a life.
With no one yet charged over the attack, she urged the perpetrators to hand themselves in.
Constable Kerr, 25, from Beragh, Co Tyrone, died when a booby trap bomb exploded under his car in nearby Omagh on April 2 last year.
The Catholic gaelic footballer, who had been in the force for only three weeks, was apparently targeted in a bid to scare other young nationalists from joining Northern Ireland's new-look police service.
In the wake of the murder, Mrs Kerr made an emotional plea for Catholic trainee recruits and police officers to defy the killers and continue to serve.
