The Special Criminal Court has heard murder accused Wayne Dundon had a notorious reputation among Limerick gardaí.
The 35-year-old of Lenihan Avenue, Prospect and his co-accused Nathan Killeen of Hyde Road, Prospect deny killing businessman Roy Collins at the amusement arcade he ran at the Roxboro Shopping Centre, on April 9, 2009.
The non-jury court has been hearing garda notes have very recently come to light implicating Wayne Dundon in the 2002 murder of Limerick bouncer Brian FitzGerald.
The allegations were made by the chief prosecution witness in this trial Gareth Collins during a 2011 interview unrelated to this investigation.
However, defence lawyers have said Wayne Dundon was in Portlaoise prison at the time of the FitzGerald murder.
The evidence goes to the credibility of Gareth Collins's testimony.
He said he was offered €20,000 by Wayne Dundon and Nathan Killeen to act as a getaway driver in the Roy Collins shooting, five years ago.
The 35-year-old businessman died from a bullet wound to the chest.
