GREENSBURG, Kan. (AP) – Rescue teams searching the rubble that was once Greensburg found two more victims and a survivor, raising the death toll from a powerful tornado that largely obliterated the small community to at least 10, authorities said Monday.

The massive tornado, an enhanced F-5 with wind estimated at 205 mph, was part of a weekend of violent storms that tore across the Plains and was blamed for at least 12 people statewide.

Little remained standing Monday but the grain elevator as the town’s 1,500 residents were allowed back in to check their property. The tornado demolished every business on the main street. Churches lost their steeples, trees were stripped of their branches and neighborhoods were flattened. Officials estimate as much as 95 percent of the town was destroyed.

One of the latest two victims was found under debris in the middle of town, city administrator Steve Hewitt said. The other body was pulled from a nearby lake.

Rescue teams also found a survivor as they searched the wreckage on Sunday, two days after the tornado hit, providing hope for other discoveries, said Kansas Highway Patrol spokesman Ron Knoefel. He did not release further details on the survivor’s identity or condition, and authorities have not identified any of the victims.

There remained plenty of caution about what the rubble might reveal in the coming days. Since the tornado hit Friday night, emergency responders have had little indication of how many people may be safely staying with friends or relatives, rather than in shelters. The sheer amount wreckage made the search effort that much harder.

“We’ve been over the town twice now – all of our partners around the state, the experts from cities with technical search-and-rescue,” Major General Todd Bunting, the state’s adjutant general, told CNN Monday morning. “We’ve done everything we can.

“Some of this rubble is 20, 30 feet deep. That’s where we’ve spent all our efforts, and we’ll do it again today.”

Some of that search effort was stalled at midday when a tank holding anhydrous ammonia – a toxic substance used as fertilizer by farmers – began leaking, prompting officials to evacuate the northeast part of the town.

At the edge of the city Monday, evacuated residents waiting to get back to their homes for the first time since the tornado struck on Friday sat in a line of vehicles as police checked identification. Utility repair crews arriving from other cities added to the traffic jam.

Police also used the opportunity to collect names and compile a list of people whose whereabouts hadn’t been determined.

A scene near downtown typified the misery residents were experiencing in their grim march back to town. A woman, supported by two others, walked along U.S. 54, stopping frequently as she broke down in sobs.

Insurance agent Scott Spark, a 13-year resident of Greensburg, hauled papers out of his wrecked office near downtown. He had already been to his destroyed home.

“I could probably have salvaged some more stuff if I had been able to get back, but I understand how it is,” he said of the restrictions. “I mean, they were still having tornadoes last night. I understand they want everybody to be safe.”
