It was a difficult day of testimony today at the Marathon bombing trial. Several victims took the stand to share their memories of what happened on that day. Among them, Bill Richard, father of 8-year-old Martin Richard, who was killed in the attack and Jeff Bauman, who lost both his legs as a result. The stories they told were horrific and heartbreaking.
