A survivor of the 2013 Boston Marathon bombings gave graduates a message of hope and inspiration Thursday evening during the Ogeechee Technical College 2015 Spring Commencement ceremony. The commencement was held at 7 p.m. in Georgia Southern University’s Hanner Fieldhouse. Heather Abbott, who walked gracefully to the podium in four-inch heels, suffered a leg amputation after three surgeries failed to save her shattered limb.
