Fire caused $70,000 in damage to a home in the 1400 block of North 65th Street on Sunday morning.
A neighbor saw smoke coming from the attic, Deputy Fire Chief James Case said. The homeowner was able to exit the home; there were no injuries.
"The exact cause is undetermined, but (it's) suspected to be electrical in nature," Case said.
It took 45 minutes to extinguish the blaze and Wauwatosa firefighters received assistance from the Elm Grove, Brookfield, Butler, North Shore and West Allis departments.
