The convicted killer of two-year-old Santina Cawley allegedly wrote to the slain child’s distraught mother, saying she “will not ever accept blame for something I did not do". 

Karen Harrington was found guilty of the little girl’s murder this year, and is serving a life sentence in Limerick Prison.
