BOSTON -- In a rare move meant to ensure the safety of Boston-area residents and lead to the capture of the remaining Boston marathon suspect, authorities have placed the Boston area and suburbs on a lockdown and asked people to stay home and keep their doors closed.
"All of Boston" should shelter in place, Massachusetts Gov. Deval Patrick told reporters. The same applies to suburbs of Watertown, Newton, Belmont, Cambridge and Waltham, he said.
At about 6:40 a.m. central time, Boston police tweeted: "Door-to-door search 4 suspect in Watertown continues. Uniformed officers searching. Community consent critical."
All mass transit and taxi service in the city of Boston have been suspended pending further notice. Furthermore, many of the area hospitals were on lockdown, with 'minimum entrances' open. Elective surgeries and visitor access were canceled at one hospital. At Boston Children's Hospital, patients would not be discharged.

Other information released Friday morning by authorities:
- Late Thursday evening, a university police officer, Sean Collier, 26, died after being shot on the MIT campus in Cambridge.
- The brothers hijacked a car at gunpoint in Cambridge. They released the driver a half-hour later at a gas station. As police picked up the chase, the car's occupants threw explosives out the windows and shot at officers. Police shot at the car and hit the older brother, they say, who later died at the hospital. The younger brother escaped on foot.
- Older brother, Tamerlan Tsarnaev, was wearing explosives and an explosive trigger when his body was recovered, according to authorities. His brother, Dzhokhar, is another suspect and he remains at large.
- Connecticut State Police say the Boston bombing suspect may be operating a gray Honda C-RV with Massachusetts registration 316 ES9.
- Massachusetts State Police, on its official Twitter feed, warns Watertown residents to stay in their homes and to not answer the door "unless it is an identified police officer." "If any concerns about someone at door, call 911 immediately. Repeat--Do not answer door, stay away from windows, keep doors locked," the state police said in another tweet.
- Dzhorkhar Tsarnaev came to the United States as a tourist in the early 2000s and asked for asylum while he was here, a federal source said. He was naturalized last year. Tamerlan, the brother who was killed, came "a few years later" and was a green-card holder, not a naturalized citizen, the source said.
