WAYNE Dundon has begun studying constitutional law in prison after being charged with the murder of Roy Collins.
The Irish Independent has learned that Dundon is currently passing the weeks behind bars by studying the constitutional law of the State ahead of his upcoming trial.
Dundon (34) is due to appear before the Special Criminal Court on April 23 after he was charged last month with the murder of Mr Collins (34).
Following his initial court appearance when he was first charged with the 2009 murder, Dundon was remanded in custody to Portlaoise Prison.
His trial is not expected to be heard for several months.
He was previously sentenced to six years' imprisonment after he made a threat to Alice Collins at her home in Limerick in 2010 that he would kill her sons, Gareth and Jimmy Collins.
Dundon was also sentenced to a concurrent four-year sentence for threatening to intimidate two potential witnesses.
He was jailed last year after trials at the non-jury Special Criminal Court, which normally deals with terrorist offences.
At last year's trial, he contracted the services of a Belfast-based solicitors' firm Madden & Finucane.
Roy Collins, a father of two, was shot in the Coin Castle amusement complex at the Roxboro shopping centre on April 9, 2009.
The murder occurred four years after members of the Collins family testified against Dundon.
