Here are the two brothers taking cover behind the black Mercedes SUV and shooting towards Watertown Police officers. (Taken at 12:46:11AM)
This is a zoomed in view from the last image. The red circle highlights the pressure cooker bomb that was used just moments after this photo was taken. The use of this explosive created an enormous cloud of smoke that covered the entire street. While the street was still cloudy with smoke one of the brothers started running down the street towards the officers, while still engaging them in gunshots. As he got closer to the officers, within 10 -15 yards of them he was taken down. From my vantage point I did not see whether he was tackled to the ground or brought down by gunshots.
This is a zoom-in from the last image and the red circle highlights where one of the brothers was taken down and still laying in the street. The black SUV proceeded to accelerate towards the officers and drove in between the two cars at the top of the picture. The SUV side swiped both cars taking out doors and windows and ultimately broke through the vehicle barricade and continued driving west on Laurel St. This was the last I saw of the black SUV.
