The family of slain 7-year-old Somer Thompson is preparing to lay the child to rest, a week after she vanished in north Florida on her way home from school.

A viewing was scheduled in the Jacksonville suburb of Orange Park on Monday night, followed by a Tuesday morning funeral. After the final services, mourners plan to launch thousands of purple balloons.
