Last night we told you about a fire that destroyed part of an apartment building in Twin Falls.
The blaze started at around 4 am Thursday morning at a 4-plex at 374 Madrona Street.
Today Captain Matt Hicks say officials are continuing their investigation.
They still don't know if the fire is suspicious or if it was an accident.
Hicks say investigators are focusing on the front porch area of the complex.
But he says it could have started somewhere else.
The fire destroyed the second level and caused extensive damage two the bottom apartments.
Four families were displaced and the American Red Cross is helping them by providing food, clothes and shelter.
They say this is a rare occasion for the Red Cross to provide help to four families at once.
Volunteers say this is their most expensive effort in south central Idaho since last year.
