BOSTON MARATHON BOMBING SUSPECT 1 KILLED Hunting for Suspect 2


Cops have shot and killed one of the men suspected in the Boston Marathon bombing -- after a fierce gun battle in Watertown, Mass. ... and now officials are on the hunt for Suspect #2.

Here's what you need to know ...

-- The suspects are brothers from Chechnya ... 26-year-old Tamerlan Tsarnaev and 19-year-old Dzhokhar Tsarnaev. They reportedly moved to the U.S. around 2002 and have been living here legally.

-- The brothers were located in Watertown, Mass. last night ... after they allegedly robbed a 7-11 store and hijacked a car. The driver of the car was unharmed.

-- The brothers then shot and killed a security officer on the M.I.T. campus -- and cops came racing to the scene.

-- A ferocious gun battle ensued ... and the brothers reportedly threw grenades at the cops.

-- The older brother, Tamerlan, was killed in the shootout ... but Dzhokhar escaped.

-- Cops believed Dzhokhar is armed and dangerous ... and has a bomb strapped to his chest.

-- Officials have launched an intense manhunt for Dzhokhar ... and have released a new picture of the 19-year-old.


There are reports the older brother was a boxer who wanted to become part of the U.S. National Boxing Team.

-- At least one of the brothers went Cambridge Rindge and Latin School ... where Matt Damon and Ben Affleck went to school, according to reports.

The question now ... are these brothers -- who have presumably been Americanized and living in the U.S. for years -- considered domestic or foreign terrorists.
 Police in Niagara Falls, N.Y., have pulled over a pair of Russian nationals this morning and reportedly have robot and bomb techs on the scene to investigate suspicious packages. It's unclear if there is a connection to the Boston Marathon bombing.

According to Buffalo television station WGRZ, the FBI has been notified and the joint terrorism task force is working with state police
