The Taoiseach and Justice Minister are to be briefed on the investigation into Keane Mulready Woods' murder today.
His partial remains were found in North Dublin this week, and Gardaí are seeking help in tracking the movements of a car.
Gardai last night revealed that the burnt-out car was a blue Volvo V40 which was stolen from Sandymount in Dublin on December 15th.
Gardai are keen to discover where it was stored after that date - its registration plates were 161 D 48 646 - but they were changed to false registration 141 MO 1925.
Gardai would like to know where those plates were bought or constructed.
The car also had four matching alloy wheels when stolen but one of them had been changed and again investigating officers are looking for anyone who may have information about that wheel change
They are also looking for dashcam footage from anyone who travelled through Ballybough Rd, Clonliffe Rd, Poplar Row or Luke Kelly Bridge between midnight last Tuesday and 2 am on Wednesday.
Anyone with information can contact Drogheda Garda Station, the Garda Confidential Line or any Garda Station
