Toledo firefighters called out on a vacant house fire in the 600-block of Pinewood early Wednesday morning.
The call came in just after 2:00 a.m. The blaze started on the first floor and spread to the top, which quickly became fully engulfed in flames.
Firefighters were able to get the fire under control quickly, but the vacant house will be a complete loss.
Arson investigators are trying to figure out what started that blaze.
