Suspect Manhunt Puts Boston on Lockdown by Jerome Socolovsky A massive manhunt is underway Friday morning in Boston and surrounding towns for a suspect in Monday's marathon bombing, following an overnight gunfight that left a policeman and a second suspect dead. The suspects were driving a carjacked Mercedes SUV and police chased them after they were called to the scene of a robbery in Cambridge, across the river from Boston. Authorities say the suspects had fatally shot a campus police officer at the Massachusetts Institute of Technology. Police say explosive devices were thrown at them from the fleeing car, and in an exchange of gunfire one of the suspects was shot, while the other fled in the vehicle. Ed Davis, the commissioner of the Boston police department, said they believe the suspect is a terrorist. "We believe this to be a man who has come here to kill people," he said. "We need to get him in custody.'' The first suspect was taken with multiple gunshot wounds to a hospital, where he was pronounced dead. Reports say the suspects are brothers of Chechen origin who had been living in the Boston area for about a year. Police had earlier released images of them near the finish line of the Boston Marathon. '' Authorities are urging residents throughout Boston and a number of its suburbs to stay indoors, as police lay a dragnet for the suspect. Classes have been cancelled at schools and universities, and the entire public transport system of the Boston metropolitan area has been shut down. Monday's bombings at the Boston Marathon killed three people and left more than 170 injured. __________________________________________________________________ [1]http://www.voanews.com/content/boston-on-lockdown-as-police-conduct- manhunt/1644800.html References 1. http://www.voanews.com/content/boston-on-lockdown-as-police-conduct-manhunt/1644800.html
