Minneapolis Fire Department Capt. Shanna Hanson was off-duty when she heard of the I-35 bridge collapse in August 2007. Nevertheless, she grabbed her gear and dove into the Mississippi River in hopes of finding survivors. Television coverage of the disaster made Hanson a local hero. Now, accumulated injuries have taken their toll on the 19-year veteran, so she is taking a $113,000 workers’ compensation buyout and hanging up her fire helmet.
