A historic disaster: Katrina toll may climb into the thousands; looters turning brazen

As fires burned from broken natural-gas mains, the skies above the city buzzed with National Guard and Coast Guard helicopters frantically dropping baskets to roofs where victims had been stranded since the storm roared in with a 145-mph fury Monday. Atop one apartment building, two children held up a giant sign scrawled with the words: "Help us!"

Looters used garbage cans and inflatable mattresses to float away with food, blue jeans, tennis shoes, TV sets — even guns. Outside one pharmacy, thieves commandeered a forklift and used it to push up the storm shutters and break through the glass. The driver of a nursing-home bus surrendered the vehicle to thugs after being threatened.

Police said their first priority remained saving lives and mostly just stood by and watched the looting. But Nagin later said the looting had gotten so bad that stopping the thieves became the top priority for the police department.

"They are starting to get closer to heavily populated areas — hotels, hospitals — and we're going to stop it right now," Nagin said in a statement to The Associated Press.

Hundreds of people wandered up and down shattered I-10 — the only major freeway leading into New Orleans from the east — pushing shopping carts, laundry racks, anything they could find to carry their belongings.

On some of the few roads that were still open, people waved at passing cars with empty water jugs, begging for relief. Hundreds of people appeared to have spent the night on a crippled highway.

Starting Thursday, authorities planned to move at least 25,000 storm refugees to the Astrodome in a vast convoy of some 500 buses provided by the federal government. With the air-conditioning knocked out, the Superdome has become stifling, its toilets are broken, and there is nowhere for anyone to bathe.

Nagin, whose pre-hurricane evacuation order got most of his city of a half a million out of harm's way, estimated 50,000 to 100,000 people remained, and said that 14,000 to 15,000 a day could be evacuated in ensuing convoys.

"We have to," Nagin said. "It's not living conditions."

He also expressed concern about people staying in the water: "People walking in that water with those dead bodies, it can get in your pores, you don't have to drink it."

In addition to the Astrodome solution, the Federal Emergency Management Agency was considering putting people on cruise ships, in tent cities, mobile home parks, and so-called floating dormitories.
