BOSTON - Black Hawk third grade teacher Kristina Rynes ran around a corner moments after two bombs exploded near the finish line of the Boston Marathon Monday, killing three and injuring at least one hundred others. Rynes, of Monroe, finished the Boston Marathon in 3 hours, 23 minutes and 30 seconds. She then lingered around Boylston Street near the finish before scurrying with thousands others after an explosion rocked Boston before the finish of the event.
