Colorado wildfire: search for three missing as officials investigate blaze

Officials pursue tips and search crews sort through debris for three missing people after flames destroy nearly 1,000 homes

Search teams looked for three missing people on Sunday in snow-covered but smoldering debris from a massive Colorado wildfire, while people who escaped the flames sorted through what was left and investigators tried to determine its cause.

The flames ripped through at least 9.4 sq miles and left nearly 1,000 homes and other buildings destroyed in suburbs between Denver and Boulder.
