The young brother was at his college dorm room yesterday around noon, and gave a lift to someone in his car.
They didnt expect to get caught at all.
Last night after the FBI released the video and photos, the brothers saw that on television and went crazy. They robbed the 7-11 for quick money, saying to the employee there 'we ARE the Marathon Bombers' ..the MIT security guard apparently heard the 7-11 call on his scanner and went to see what he could do.
After that they carjacked the Mercedes and kept the driver hostage while they drove around to ATM's trying to get money. They dump the driver off unharmed and the driver calls the cops. Police quickly spot the Benz and a pursuit ends when it pulls over. Firefight. Older brother hurls a pressure cooker bomb at a squad car but the lid comes off as it explodes, reducing its effect. Apparently part of the pressure cooker gets embeded in a police car.
Older brother drops from gunshot wounds. Younger brother hops in the Benz and tries to escape, backing up over his brother in the process. Goes a few miles then abandons the car, runs away on foot.
