BURNS, Oregon: The cost of the six-week standoff in rural Oregon that ended peacefully on Thursday will likely cost millions of dollars, with local and state agencies looking to the federal government — and the arrested occupiers — to shoulder the bulk of the bills.

Police and federal agents searched the wildlife refuge for explosives and evidence on Friday.

Federal authorities said the Malheur National Wildlife Refuge in eastern Oregon would remain closed for several weeks as agents secured what is now considered a crime scene.

Protesters told authorities they had left behind booby traps but did not say whether the trip wires and other devices would trigger explosions, a law enforcement official, speaking on the condition of anonymity, told Reuters.

Materials to create explosives could be found on the refuge, the official said, because workers there previously performed controlled burns.

The final four protesters had enough food on hand to last them for many months, the official said.

The nearby town of Burns, which has been caught in the middle as the occupiers protested federal government control of expanses of Western land, was quiet on Friday as residents sought to resume normal life after the 41-day standoff.
