Massachusetts Governor Deval Patrick said any concern of additional terror attacks in Boston were baseless and there is currently no "imminent threat."
Focus turns now to the question of "why," as investigators hope to find a motive for the attack that left three dead and over 170 more injured. Travel has been an area of concern for investigators. Tamerlan Tsarnaev, the older of the two suspects, went to Russia for six months last year, and authorities believe he may have been radicalized on that trip.
House Intelligence Committee Chairman Mike Rogers highlighted how much attention authorities are paying to that trip, saying, "that six and a half months becomes incredibly important. And it would lead one to believe that that's probably where he got that final radicalization to push him to commit acts of violence."
Rogers also added that while in Russia, Tsarnaev may have traveled under an alias.

Also, don't miss a special discussion about how Boston will bounce back from the bombings. As Boston-native Doris Kearns Goodwin put it, "We belong to our families, we belong to our communities, but sometimes you really realize you belong to your hometowns. I'm so proud of what Boston did this week."
Thoughts and prayers go out to the Boston community and all those affected by this tragedy.
