Murder trial of Wicklow man continues

The Central Criminal Court has heard that detectives travelled to Austria and Switzerland with a can of Red Bull discovered at the scene of a fatal shooting, in an effort to establish if it had been bought at a Dublin Spar shop.

The evidence was heard on day four of the murder trial of Wicklow man Garrett O'Brien, who is accused of shooting dead Stephen O'Byrne at his home in Tallaght in March 2009.
