Garda killer Stephen Silver will serve his life sentence in Mountjoy Prison.
The Irish Prison Service has no plans to move him and say so far he is a "model prisoner" who is full of remorse.
The former motorbike mechanic, who shot hero detective Garda Colm Horkan 11 times, was sentenced to the mandatory 40-year sentence for capital murder. With remission, he will serve between 26-and-a-half and 30 years behind bars and so he will be at least 73 years old before he can be freed.
