Nearly 500 people were still unaccounted for today in Larimer County, Colo., alone in wake of the ferocious flooding that has ripped through the state, killing at least four people.
Nick Christensen, a spokesman for the Larimer County Sheriff's Office, admitted that the death toll is expected to rise, but said the list of 482 people unaccounted for in the county should shrink drastically.
"It may be a book-keeping, cross-referencing issue," he said. "There's been lots of parties that have been evacuated, we've had trouble with phone service and so we have a master list that will get shorter, hopefully far, far shorter, as time goes by and we cross reference and determine where each of those parties are."
Larimer County Sheriff Justin Smith told ABC News he hoped the number would come down dramatically, as rescuers were reporting miracle after miracle in their search efforts.
He fought back tears as he described what he saw after touring the county today.
"I know exactly inch by inch, mile by mile, community by community, they're taking this stuff back, they're doing it, people are getting those things done out there," he said. "I was devastated by what I saw in there and you had no feel that there was any hope -- it felt hopeless in a lot of those areas from the air."
Statewide, nearly 1,300 are unaccounted for as a result of the rising floodwaters that have destroyed homes and wiped out roads in the Centennial state.
