FOND DU LAC - Investigators are looking for what caused an early morning apartment fire in Fond du Lac that displaced at least four families.
Crews arrived at about 3 a.m. Friday to heavy fire and smoke on the second floor of a Hometown Harbors apartment building.
Everyone got out safely and no one was injured.
It took firefighters about 30 minutes to get the fire out. They say the fire was mainly contained to the four apartments on the north end of the building and a firewall helped keep the fire from spreading to the other eight units.
FOX 11 talked to Kelly Dvorak who said the fire started in her apartment and believes it was set intentionally.
"I have my suspicions, seeing as how I had my patio door locked and closed, I had my bedroom window closed with a screen on it," said Dvorak. "My screen is missing, by bedroom window is open and my patio door is open, so I definitely have suspicions on it, but it wasn't just something that happened out of electric or nothing like that. I definitely don't think that what so ever."
Officials said it was too early to say what exactly happened.
"All I can tell you is that we're going to do a fire investigation," said Division Chief Troy Haase of the Fond du Lac Fire Department. "We don't know anything. It's a lot of hearsay in a lot of cases. There's no facts yet and when we go through, we'll investigate and we'll see what we can come up with."
The Red Cross and Alliant Energy are assisting those affected by the fire.
