Consultant psychiatrist at the Hermitage Clinic in Dublin Patricia Casey, says she previously called for a national review to be set to into tragedies of this type.
"The years ago I approached the Minister for Justice with a view of setting up a national review of these, to examine the factors that were at play over the previous ten years as there had been quite a number then.
