Italian probe focuses on poor construction

Italian authorities are vowing to investigate whether negligence or fraud in adhering to building codes played a role in the high death toll in last week's earthquake in Italy.

They also called for efforts to ensure organized crime doesn't infiltrate lucrative construction contracts to eventually rebuild much of the picturesque towns leveled in the disaster.

Meanwhile, rescue workers pressed on with the task of recovering bodies from the rubble, with hopes of finding any more survivors virtually vanished more than four full days after the powerful quake.
