ORANGE PARK, Fla. AP – 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.
