Feds seek suspects, motive in Boston bombings


BOSTON, MA (WKOW) – The FBI served a search warrant late Monday night on a home in suburban Boston in the investigation into the Boston Marathon bombing attack.

Massachusetts State Police have confirmed that a search warrant related to the investigation was served in Revere, but they haven't said anything else.

Some investigators were seen leaving the house early Tuesday morning, carrying brown paper bags, plastic trash bags and a duffel bag.

Authorities say police were at an apartment complex for about 8.5 hours Monday night and they could be seen questioning two men and looking at passports.

So far, authorities say no arrests have been made and they don't have a motive.

The FBI is asking for any video, audio or photos taken by marathon spectators.

Two bombs went off Monday afternoon as thousands of Boston Marathon runners had yet to cross the finish line.  Officials confirm that three people were killed, including an 8-year-old boy, and more than 150 people were injured.  Many suffered ruptured eardrums, broken bones and severed limbs.

President Obama addressed the situation at the White House on Monday and was careful not to use the word "terrorism."  An administration official says the attack is being treated as an act of terrorism. President Barack Obama vowed that those responsible will "feel the full weight of justice."

Authorities say the Pakistani Taliban said on Tuesday that it had nothing to do with the attack.

The area around Copley Square remained closed Tuesday morning, as did exit ramps from major highways to the area. 

Authorities say the Federal Aviation Administration barred low-flying aircraft within 3.5 miles of the site. Other cities also beefed up security in response to the bombing and the Secret Service expanded its security perimeter around the White House.

The FBI, U.S. Attorney's office and other law enforcement officials planned to brief the media at 9:30 a.m. Obama will be briefed Tuesday on the investigation and the ongoing response efforts from FBI Director Robert Mueller, homeland security assistant Lisa Monaco and other senior members of his team.
