An intense search began this morning, for the main suspect behind the Boston Marathon bombings, Dzhokhar A. Tsarnaev, a 19-year-old immigrant.

Dzhokhar A. Tsarnaev, 19, and his brother, Tamerlan, 26, are both suspects behind the bombings, however, his brother was killed in a police confrontation last night, according to Daily Mail.

"Tamerlan died in hospital with multiple gunshot wounds and possible blast injuries after a fierce gun battle late last night," wrote Daily Mail.

A spokesman for the Massachusettes State Police, David Procopio, said that the manhunt began after the brothers apparently robbed a 7- Eleven near the campus of MIT at around 10:20 p.m., according to The Washington Post. "They allegedly shot the Sean Collier, a 26-year-old MIT campus police officer, as he sat in his car," wrote The Post.

The suspects have been identified as coming from an area in Russia near Chechnya, an area plagued with an insurgence of Islam, according to The Associated Press. Dzhokhar Tsarnaev has been identified, by the AP, to have been living in Cambridge, close to Boston and said to possibly be, "armed and dangerous."

"We believe this man to be a terrorist.  We believe this to be a man who's come here to kill people," said Boston Police Commissioner, Ed Davis during a press conference this morning, according to the The Inquisitr.

Law enforcement officials said they believe Tsarnaev may be strapped with explosives on his person and they are being very cautious in an effort to avoid further casualties, according to The Washington Post.

"Police are staking out a house in a Boston suburb as part of a frantic search for a suspect in Monday's marathon bombing after a bloody night of shooting saw a second suspect and a police officer killed," wrote to The Independent, at around 8 this morning. 

While attempting to evade authorities, the suspects killed a university police officer, injured a transport officer, and throw explosives at police, according to The Independent.

"All public transportation was shut down in the greater Boston area Friday morning, officials said, and no vehicle traffic was permitted in or out of Watertown during the massive manhunt," according to The Washington Post.  Residents surrounding the Boston area have been asked to stay inside and keep their doors locked and businesses, colleges and universities have been closed for the day.

A spokesman for the Massachusetts State Police said that police closed a portion of Norfolk Street in Cambridge where that think Tsarnaev may be located, according to The Washington Post. "We don't know if he's there. There is a possibility the suspect is there," said the spokesman, David Procopio.
