Investigators dig for bomb motive, warn more could be found
WASHINGTON — Investigators searched coast-to-coast Thursday for the culprit and motives behind the bizarre mail-bomb plot aimed at critics of the president, analyzing the innards of the crude devices to reveal whether they were intended to detonate or simply sow fear two weeks before Election Day.
Three more devices were linked to the plot — two addressed to former Vice-President Joe Biden and one to actor Robert De Niro — bringing the total to 10 in an outbreak of politically loaded menace with little if any precedent. Authorities warned there might well be more.
Law enforcement officials told The Associated Press that the devices, containing timers and batteries, were not rigged like booby-trapped package bombs that would explode upon opening. But they were still uncertain whether the devices were poorly designed or never intended to cause physical harm. A search of a postal database suggested at least some may have been mailed from Florida, one official said. Investigators are homing in on a postal facility in Opa-locka, Florida, where they believe some of the packages originated, another official said.
The officials spoke on condition of anonymity because they were not authorized to discuss the ongoing investigation by name.
