Monday, May 12th, 2008 — Crews and search dogs hunted Sunday for survivors or bodies in piles of debris after tornadoes and storms rumbled across the region a day earlier and killed at least 23 people in three states. Seven people died in Picher, once a bustling mining center of 20,000 that dwindled to about 800 people as families fled lead pollution here, and officials held out hope that they wouldn’t find any more bodies.
