Padraig O'Morain: Why were the boys in his house, what was going on?

The killing of Aidan O'Kane by teenager Conor Duffy in 2008 was a shocking act.

But those who have followed the trial will wonder if something could have been done earlier to prevent the tragic chain of events that led to his death.

When Mr O'Kane moved into his East Wall home he befriended a group of teenagers in the locality.

He repaired their bicycles and motor bikes and allowed them to take drugs in his house.

Nervous

We do not know what Mr O'Kane's motive was in allowing the teenagers into his home.

Perhaps he simply wanted to give them a place away from the influence of the street.

Or perhaps he was too nervous to face up to them and throw them out.

Local people, not surprisingly, complained about what was going on in Mr O'Kane's house.

A garda also warned him that what he was doing was not appropriate. But who were these teens and children, one of whom was as young as 11?

If local people and gardai were aware of what was going on, shouldn't the HSE have been? And if so, why was a situation which was creating serious tension in the locality allowed to carry on?

Tension

Mr O'Kane had been subjected to antisocial behaviour for many months before his death.

This behaviour led him to the events of that awful night.

He put on a balaclava and went out in search of the youths who had thrown eggs at his house.

It may be too late for Mr O'Kane, but answers must be found to these questions now.
