WORLD IN BRIEF: Aftershocks weaken Chile's quake-damaged buildings

CONCEPCION, Chile — A father's unanswered cry for his missing son rang out Saturday from the wreckage of a fallen 15-story apartment building that has become a symbol of Chile's devastating earthquake.

‘‘Jose Luis! Jose Luis!'' cried the man, Jose Leon, peering into holes in the concrete that had been carefully cut by rescuers who used body-sniffing dogs to help recover victims.

Emergency workers said Saturday that there is no hope of finding more survivors in the building, and that continuing aftershocks have made the rubble too unstable for firefighters to continue looking for 21-year-old Jose Luis Leon, the only known remaining victim not recovered. Shortly afterward, a huge yellow excavator began clawing into the concrete slabs and twisted metal to demolish the structure.
