A man told his cousin he stabbed a Kilkenny woman to death because she had stolen a “vial of his blood”, “installed hidden cameras”, and put “black widow spiders” in his house, a jury has heard.

A murder trial jury has heard that when a security guard at a Kilkenny shopping centre confronted a man who had repeatedly stabbed a woman, he did not see “any emotion in him” and “he was so calm after what he had done”.
