Florida ? Investigators had more than a thousand tips but are still trying to figure out what happened when 7-year-old Somer Thompson disappeared on her walk home from a north Florida school last week.

At a fundraiser Sunday for Somer’s family, children played in a bounce house as adults watched carefully. They vowed to find the girl’s killer and raised about $18,500 so her mother doesn’t have to go back to work immediately.

Somer’s name and photo were everywhere at the carnival-like fundraiser, which was held in a tree-lined park in the town’s center. A silent raffle, a bake sale and even glittery makeovers for little girls were offered to help the family after the girl went missing after school Monday. Her body was found in a Georgia landfill Wednesday.

So far, no one has come forward to say they saw the girl abducted or attacked. Investigators have ruled out all 161 registered sex offenders who lived within a 5-mile radius of Somer’s home.
