Firefighters helped a woman who was trapped under a heavy piece of furniture at work in downtown Madison Tuesday afternoon. The Madison Fire Department said an employee at a business in the 300 block of East Wilson Street was rearranging files alone in a locked room when the top drawer of the file cabinet caused it to become top-heavy and tip over. The woman was able to catch the cabinet before it struck her, but it was too heavy for her to push back into position, according to the report. She slid to the floor and was trapped underneath the cabinet.
