Crews race to find tornado survivors ahead of storms

EMERGENCY crews drilled through concrete at a ruined Home Depot, making peepholes in the rubble in hopes of finding lost shoppers and employees.

A dog clambered through the shattered remains of a house, sniffing for any sign of the woman and infant who lived there.

Across devastated Joplin, searchers move from one enormous debris pile to another, racing to respond to any report of a possible survivor.
