"So far, no septic tank has been found."
The septic tank claim was laid to rest (more decently than the children were) some tome ago - it is you who has kept it alive to divert from the real issue - the horrifically inhuman treatment of "sinners" at the hands of those calling themselves Christians, with the full collusion of the Irish Government - that is, and has always been the real issue.
