Milwaukee’s fire department is calling a house fire in the city’s Riverwest neighborhood on Tuesday an arson.
The first started a house that is being renovated but spread to six other houses.
In all, seven people are now homeless because of the fire.
Investigators are certain that someone intentionally set the fire, but they are not saying how.
There’s also no word on suspects.
This is the second string of arson fires in Milwaukee this summer.
The other case, from June, involved eleven different fires.
A suspect was arrested in that case.
