WATERTOWN — State police say officers are going door-to-door, but the Boston Marathon suspect is still on the loose.
Col. Timothy Alben of the Massachusetts State Police said this afternoon that officers would go street to street as the manhunt for the bombing suspect continues. Gov. Deval Patrick urged residents to continue staying indoors.

Twenty-six-year-old Tamerlan Tsarnaev was killed overnight. His 19-year-old brother, Dzhokhar is on the loose.

Tamerlan Tsarnaev, a 26-year-old who had been known to the FBI as Suspect No. 1 and was seen in surveillance footage in a black baseball cap, was killed overnight, officials said.

Authorities in Boston suspended all mass transit and warned close to 1 million people in the entire city and some of its suburbs to stay indoors as the hunt for Suspect No. 2 went on. Businesses were asked not to open. People waiting at bus and subway stops were told to go home.
From Watertown to Cambridge, police SWAT teams, sharpshooters and FBI agents with armored vehicles surrounded various buildings as police helicopters buzzed overhead.
