Hundreds believed dead in America due to heat wave

Many of the dead were found alone, in homes without air conditioning or fans. Some were elderly — one as old as 97. The body of an immigrant farm laborer was found in an Oregon nursery.

As forecasters warned of a record-breaking heat wave in the Pacific Northwest and western Canada last weekend, officials set up cooling centers, distributed water to the homeless and took other steps. Still, hundreds of people are believed to have died from Friday to Tuesday.
