OREM -- Melanie Woodruff smelled smoke Thursday afternoon so she ran outside. Minutes later, as she drove around her neighborhood, she saw flames engulfing a neighbor's house.

"You should have seen the black smoke," she added.

Fire officials say the blaze broke out at 262 E. 700 North in Orem at 4:36 p.m. The cause of the fire remained unknown Thursday evening, but battalion chief Jason Earl said it apparently started outside the home. From there, the fire moved into the kitchen and then into the attic. Earl estimated the damage at about $100,000. He added that the damage extended into roughly three-fourths of the home.

The fire displaced five adults and three children who were living in the small, yellowish-brown home. According to Earl, a man and a child were in the home when the fire started. The man smelled smoke, ran outside and saw that the back of the house was on fire. He then called 911.

Earl said it took crews roughly 20 minutes to control the fire and 30 minutes to extinguish it. Crews from all Orem fire stations responded.
