The massive scope of the Regency Hotel murder investigation has again been laid bare before the trial of Gerry Hutch.
On Tuesday the trial was shown a total of 83 separate maps - each depicting cell site locations that were examined by gardai in this case - across counties Dublin, Louth, Monaghan and Donegal.
The cell sites were used by gardai to obtain and examine phone records - including calls, texts and location data in the case - after seizing phones from the likes of Jonathan Dowdall, his father Patrick, Patsy Hutch, and co-accused man Paul Murphy.

Details of this analysis are set to be heard on Thursday when Sarah Skeed, a phone analysis expert, will take the witness stand.
Today, however the trial heard details of each and every cell site phone tower that was of interest in this murder trial - revealing locations around key areas - such as around the Regency Hotel on the Swords Road in Dublin, where the murder took place.
Gerry Hutch has denied murdering Kinahan cartel associate David Byrne (34) in the Regency Hotel on February 5, 2016.
Co-accused men Jason Bonney and Paul Murphy meanwhile deny separate charges of facilitating that murder by providing vehicles that aided the hit-team in escaping that day.
