Elzbieta Vilka was seriously wounded. Physically, the children were not physically disturbed, but the incident left a serious emotional impact.
After this incident, the children's wife returned to the original Poland.
Investigators in Ireland believe that the murder was done by the gangs of Latvia and Lithuania, who were assisted by local Irish criminals.
