Tallaght murder accused knew prison officers would read 'Two in the head' letter

The teenager charged with murdering Melanie McCarthy McNamara was a protected prisoner when he allegedly wrote a letter containing the phrase: "Two in the head. The bitch is dead".

Daniel McDonnell’s murder trial heard that he had a cell to himself and no contact with other prisoners for his own protection when detained in St Patrick’s Institution on suspicion of the murder. It also heard that he would have known his post would be read.
