Boston bombers are Chechnyan radicals

Special Report from Stratfor...

Boston - Just after 10 p.m. on April 18, the Tsarnaev brothers were identified after having robbed a convenience store in Cambridge, Mass., just three miles from Boston, hours earlier. A Massachusetts Institute of Technology police officer, who responded to the robbery, was shot and killed and found in his car by fellow responding officers. The two suspects later hijacked an SUV at gunpoint, releasing the driver unharmed. Authorities later caught up to the suspects, and a car chase ensued. 

Just after midnight, the car chase ended with a gunfight in Watertown, Mass. The suspects reportedly threw explosive devices at police, though it is not yet confirmed what types of explosives allegedly were used. During the firefight, Tamerlan Tsarnaev was wounded, taken into custody and later reported dead. Some press reports suggest he may have been wearing some sort of suicide belt or vest. Dzhokhar escaped by driving the stolen SUV through the police barricade and remains at large. According to media reports, a third accomplice was detained earlier this morning by authorities and is being questioned.
