People pay tribute to the Nashville school shooting victims at a makeshift memorial, lined with flowers, balloons and teddy bears, outside the Covenant School building. Earlier Monday, a heavily armed former student killed three young children and three staff in what appeared to be a carefully planned attack at the private elementary school. The suspected shooter, who was fatally shot by police, was identified as 28-year-old Audrey Hale, who the officer later said identified as transgender. IMAGES
