This from Larry Shapiro:
Wheeling firefighters were called to 697 S. Merle for a fully-involved, detached garage fire. A header was visible while companies were en route and multiple 9-1-1 calls were received. The alarm was upgraded to the Code 4 for the working fire bringing mutual and auto-aid from Buffalo Grove, Prospect heights, Long Grove, and Arlington Heights.
Here are several images from the scene plus a video.
