Cold-blooded killer

John Geary left his rented house on the morning of Nov 15, 2010, with one intention — to murder Sarah Hines.

During a sustained attack lasting nearly an hour, he inflicted 21 knife wounds on Ms Hines.

He also stabbed to death their five-month-old baby Amy, her three-year-old son Reece, and her 20-year-old friend Alicia Brough.
