Two weeks ago, 7-year-old Tiannah Antone-Federici had a heart attack, despite having no known pre-existing medical conditions.
According to CHCH News, Constable Sean Connelly of the Hamilton Police Service was the first to arrive at the elementary school. As the nine-year veteran began checking Tiannah's pulse, she began to slip away and stopped breathing.
Acting quickly, Connelly performed chest compressions and then deployed an AED, saving Tiannah's life.
Late last week, the two were reunited.
