The St. Joseph Fire Department responded to a house fire just after 9 p.m. Sunday to a home engulfed in flames in the 200 block of W Nebraska St.

Fire crews worked to contain the fire but by the time crews arrived on scene the roof was already collapsing.

Fire inspector Jason Ziph told the St. Joseph Post the home was believe to be vacant at the time of the fire. He said no utilities were attached to the structure.

Ziph said the fire department believes the fire started at the back of the building, however a cause has not yet been determined.
