Firefighters were called to 147 S. Center in downtown Casper for a report of an odorless haze, according to Capt. Justin Leinonen.

Firefighters were trying to figure out what was causing the smoke, but were using an abundance of caution to make sure the building was safe, said Leinonen.

The building houses Cadillac Cowgirl and a law office on the second floor. The haze was mainly concentrated on the second floor and could be seen escaping from top story windows.
