Hours after Tuesday's commemoration of the one-year anniversary of the twin bombings that killed three people and wounded dozens of others, police say an officer stopped a man acting suspiciously near the race finish line.
Kevin Edson allegedly told the officer that a rice cooker was in his backpack.
As a precaution, authorities blew up the backpack and another one found nearby.
DEADSPIN did some research on this guy who claims this was "performance art".
