In a game of pretend gladiators with his police officer father, 11-year-old Conor Johnson was stabbed in the heart and died four short hours later. His mother, Sharon Johnson, claimed that his medical care was inadequate with no specialist cardio-thoracic surgeons available.
Ian Johnson, 40, told a coroner’s inquest how the four-inch stainless steel knife “slipped from my grasp” during some rough and tumble play with his son, Conor, 11, while he prepared dinner. The knife pierced the left ventricle of Conor’s heart.
What a horrible thing to happen to all of them.
