A shotgun recovered from the property had not been discharged.
Anne, a nurse and mother of two, has been battling ill health over recent times and travelled to Dublin for a medical procedure in mid-October.
She was accompanied by her eldest son.
Because of the dispute over the €2m will, the mother and son did not stay at the Assolas farmhouse on their return from Dublin.
They instead stayed with friends in the Kanturk area.
However, both decided to return to the farmhouse on October 25.
This decision was prompted by the receipt of a letter on behalf of Tadg O’Sullivan which held out the prospect of an amicable settlement being achieved within the family.
