An area fire department is trying to figure out what caused an early morning fire on Chicago Avenue in Wausau Saturday morning.

Battalion Chief Doug Beula tells NewsChannel 7 that fire crews were called to the home at about 5:00 Saturday morning.

A family was home at the time of the blaze, but made it out safely.

Beula says two of the family’s dogs didn’t make it out.

The fire caused damage in 3 rooms on the first floor of the home.

Right now, they aren’t sure what caused the fire, but the Wausau Fire Department’s investigator and the Wausau Police Department are investigating.
