VILONIA, Ark. (AP) — Emergency crews worked to account for dozens of people still missing Tuesday after a powerful storm battered Arkansas with floods, high winds and tornados, snapping utility poles, twisting one tractor-trailer like a wrung dish rag and leaving at least seven people dead. A twister that hit the small, rural town of Vilonia late Monday tore roofs from homes and stores, and tossed vehicles into the air. At least four residents of the close-knit community were killed by the tornado.
