One of the most scary moments in sports history. As bombs detonated near the finish line of the Boston Marathon killing three people and injuring hundreds.
This led to an all out manhunt to find the people who did. After days it was discovered who it was and all out chaos went off.
One of the bombers was killed while the other was found hiding in a boat and remains in jail until today.
This is one of the worst tragedies in the history of sports and one of the biggest tragedies in all of American history.
