John looked around for his only daughter, 4-year-old Evie. Hours earlier, his other stepson - a withdrawn, six-foot-tall, 200-pound seventh-grader named Brian - had been sent to his bedroom.

Four kids were asking about dinner or playing videogames. As John Wilson cooked dinner for his family in March 2010, an eerie silence filled their cozy Plantation home.
