A tarp flapping in the wind is what finally brought the capture of Boston Marathon suspect Dzhokhar Tsarnaev, who was arrested by police last night. A Watertwon resident noticed that the tarp to his boat was flapping in the wind. He sent his stepson out to investigate who said he saw blood on the tarp. He looked inside the boat and there was blood everywhere and Dzhokhar Tsarnaev, who had eluded police most of the day after running over his brother earlier that morning. His brother is dead and Dzhokhar Tsarnaev, is listed in serious condition.
