PROBE HAS DOMESTIC FOCUS

With thousands of tips about the bombing flooding in -- in its first 12 hours, the government's toll-free line, 1-800-905-1514, got more than 2,000 calls -- federal investigators are now focusing more on domestic than international groups. At the Alfred P. Murrah federal building in Oklahoma City, the death toll rose to 57 today as rescue workers dug more bodies from the rubble. The building structure is now so shaky that authorities were worried that a sudden shift in the wind could endanger rescuers.Oklahoma Explosion FileOklahoma Explosion Bulletin Board
