Fire investigators are working to figure out what sparked a fire at a two-story apartment building in Morrisville Thursday night.

Crews say they will stay on the scene at the complex on Upper Main Street to access the damage and be sure the fire is out.

The fire chief says it took extra crews from Stowe to help handle the flames. When they got there, firefighters say the back of the building was on fire and so was a car parked nearby. Firefighters faced two major challenges. "The wind is half the part and the other part is that it's an older building has many roofs," Fire Chief Shawn Goodell said.

The chief says there were a lot of people home throughout the building. Luckily, he says one person smelled smoke and got everyone out OK. The Red Cross says 10 people were displaced.
