The Greensboro Fire Department says they responded to a call on Walker Avenue just before 3:00 a.m. At the scene, firefighters saw heavy fire coming out of the first and second floors of the home. The two people who lived in the house were already out when officials arrived and they were treated for smoke inhalation at the scene, but weren't taken to the hospital. A second alarm was called about ten minutes after the initial call and in total, around 45 firefighters responded to the fire, which caused significant damage. Officials estimate it did $120,000 in structural damage of the home. It took around thirty minutes to get the fire under control. The cause of the fire is under investigation and the Red Cross is helping the people who were displaced.
