The city of Boston went into lockdown on Friday morning as authorities searched for the remaining suspect in the Monday marathon bombings, the New York Times reported. The massive manhunt followed a shootout that ended in the death of the other suspect.
The ongoing search for Dzhokhar Tsarnaev, 19, came after his brother, Tamerlan Tsarnaev, 26, was killed by police after an extended chase through Cambridge and Watertown. Police are checking to see if the older brother had fastened a crude explosive device around his body before he died.
"We believe these are the same individuals that were responsible for the bombing on Monday at the Boston Marathon," Massachusetts State Police Col. Tim Alben said. The two are believed to have moved to the United States with their family from a Russian area near restive Chechnya roughly a decade ago.
A Massachusetts Institute of Technology security officer was reported shot to death by the suspects on Thursday. A Massachusetts Bay Transportation Authority officer is also believed to have been badly wounded during a lengthy gunfire exchange between the suspects and police. The pair also had prepared crude explosives that they reportedly threw at authorities.
Massachusetts Governor Deval Patrick directed all people living in Boston and the surrounding neighborhoods to "stay indoors, with their doors locked."
