Investigators are searching for the cause of an overnight fire in the city.

Reports of smoke first came in shortly after midnight, at a home along the 600 block of East 13th street.

At the scene, crews found heavy smoke mostly coming from the building's second floor. 

It forced a number of people living there out on the streets. There are no reports of any injuries, but the Red Cross was called in to help.

A fire inspector was also called to the scene.
