Hart Van Denburg/CPR News
Thursday’s wildfires in Boulder County destroyed hundreds of homes and other structures. This is what was left of one Louisville neighborhood on Friday evening, Dec. 31, as snow be began to fall.

The Boulder County Office of Emergency Management hosted a briefing to provide an update on the response to the Marshall fire that destroyed nearly 1,000 homes and left thousands of people scrambling to evacuate last week.

Two people are still missing from Thursday's Marshall Fire. However in a moment of good news, a third missing person from Louisville was found "alive and well," officials announced at a press conference Sunday.

The origin of the fires is still unknown. Gov. Jared Polis also told reporters on Sunday that the FBI is investigating the cause of Thursday's fires.
