The Tsarnaev siblings fired back (via The Boston Globe). Police officers ducked behind a tree while the brothers hurled pressure-cooker bombs at them; the explosives shook up the officers so badly that they could hardly see. But one officer was able to notice Tamerlan racing away, cutting through the backyards of local Bostonians. An officer kept firing and missing until Tamerlan was out of ammo in his gun. As a last-ditch effort, Tamerlan threw the empty gun at the police officer, who then tackled the suspect. Two other police officers joined in.

But then, Dzhokhar made a three-point turn in the SUV, turning it to face the police and his brother. He tried to run over the police — but they leaped out of the way in the nick of time. Dzhokhar, who was 19, instead ran over his own older brother, 26-year-old Tamerlan, reports The New York Times. Dzhokhar drove away, leaving Tamerlan severely wounded.
