Corpse search goes on in snow

LAFAYETTE - Light snow is falling in Walker County as search teams continue recovery work at a crematory. <br> <br> Wednesday is the 13th day of the search at Tri-State Crematory -- and it&#39;s the coldest by far. Temperatures are in the 20s, and the snow is blowing. <br> <br> Emergency management director David Ashburn says a special heated tent has been set up at the site so the work can go on. The several dozen recovery workers are also wearing special insulated coveralls Wednesday. <br> <br> Road workers also had to spread sand on the area around Walker County Civic Center. That&#39;s where relatives are going to donate blood -- in hopes their DNA will help identify more of the bodies.
