Evansville Fire Crews were called to an early Friday morning fire.
The blaze broke out shortly before 2 a.m. on West Delaware Street.
Officials say the fire started in a vacant home, but spread to the homes on both side of it, turning into a three-structure fire.
Firefighters say an elderly couple was removed from one home and one person from another home.
"The original house is a total loss," says Chief Shawn Willis, Evansville Fire Department. "It collapsed probably five minutes into our crews arriving and extensive damage to adjoining houses."
We're told a firefighter did receive burns to his face, he was treated for injury and recently released.
AMR was on scene to help those involved and the American Red Cross is assisting.
According to officials, due to the amount of damage and total destruction of the home by the fire, the cause will most likely be classified as underdetermined.
