Mid-morning update: The Boston bombing probe briefly moved across state lines to Connecticut on Friday morning, but that was quickly over. At the request of Massachusetts police, Connecticut state police were asked to look out for a gray Honda CRV that "could POSSIBLY be occupied by a wanted suspect" in the Boston Marathon boming. A short time later, Connecticut police issued a news release saying, "This vehicle has been recovered in Boston. All calls regarding this case should be directed to Boston investigators."

(CNSNews.com) - A major American city and the surrounding area was shut down Friday, as police conducted a massive, grim door-to-door hunt for a man they've described as a terrorist from Chechnya.

"We believe this to be a terrorist. We believe this to be a man who's come here to kill people. We need to get him in custody." Those are the words of a police official in Watertown, Mass., at an early-morning news conference, around 4:20 a.m., on Friday.

The second suspect was killed in a shootout with police.

The suspects have been identified as brothers -- Dzhokhar and Tamerlan Tsarnaev, Chechens who were in this country legally. Dzhokhar, 19, is still on the run.

Mass transit in the Boston area -- all buses and trains, even taxis -- as well as schools are shut down "as a safety measure," as police search for the surviving Boston Marathon bomber.

They have directed people living in the Boston area to stay indoors. Businesses should stay closed, they said.

Message from Mass. Gov. Deval Patrick at 8 a.m.

"There is a massive manhunt underway -- a lot of law enforcement involved in that. To assist that, we have suspended all service on the MBTA, our public transit service, and that will continue  until we think it's safe to open all or some of that.

"We're asking people to shelter in place, in other words, to stay indoors with their doors locked, and not to open their door for anyone other than a properly identified law enforcement officer, and that applies here in Watertown, where we are right now. Also Cambridge, Waltham, Newton, Belmont, and at this point -- all of Boston. All of Boston.

"This is a serious situation, we're taking it seriously -- we're asking the public to take it seriously as well and assist law enforcement by following those simple instructions.

"We've got every asset that we can possibly muster on the ground right now. They are doing a terrific job and workin in concert with each other, but we are going to need the public to help us help them stay safe."

Update at 6:57 a.m.: From AP sources: Boston bomb suspects are from Russia, a region near Chechnya, and have lived in U.S. legally for at least 1 year.

Update at 6:45 a.m.:
Sirens wail as buses filled with law officers leave Boston under police escort, apparently heading for Watertown, Mass., where door-to-door searches are underway. Footage aired on CNN at 6:40 a.m.

Police update shortly before 6 a.m.:

"To the residents of Watertown, Newton, Waltham, Belmont, Cambridge and the Allston-Brighton neighborhoods of Boston, we are asking you to stay home, stay indoors. We are asking businesses not to open; we are asking people not to congregate outside. We are asking people not to go to mass transit. And we are hopeful that as the day proceeds, we can provide further guidance that will be able to open portions of the (transit) system, and be able to ease these restrictions," a police official said.

No vehicle traffic will be allowed into Watertown, the focus of the search, and the place where one suspect (black hat in FBI photo) was shot and killed early this morning.

From police news conference shortly after 4 a.m. Friday:

"We believe this to be a terrorist. We believe this to be a man who's come here to kill people. We need to get him in custody." Those are the words of a police official in Watertown, Mass., at an early-morning news conference, around 4:20 a.m., on Friday.

A massive influx of police shut down Watertown, Mass., a Boston suburb, overnight, as officers raced to catch the second of two suspects in the Boston Marathon bombings. The first was shot and killed by police, but also had wounds consistent with an explosion, doctors said at a news conference.

People living within a 20-block perimeter of Watertown were warned to stay inside and open their doors only to clearly identified police officers.

Witnesses reported a wild night of gunfire and explosions in and around Watertown as helicopters beamed searchlights overhead. Hundreds, if not thousands, of police officers were said to be going door to door.

The events in Watertown followed the shooting death of a campus police officer at M.I.T., the Massachusetts Institute of Technology, Thursday night. A second police officer, a transit cop, was "badly injured," police said. Details were not available as of 4:44 a.m.

Press reports said the police chase that began at M.I.T. included a car-jacking. The suspects -- who were named on social media, but not by police -- reportedly threw explosives from the car as police chased them.

At the early-morning news conference, a police official said one suspect, the one shown wearing a black hat in the FBI photo, had been shot and taken to a hospital. He died in a shootout with police. Doctors said he also had shrapnel wounds from an explosion, suggesting he had explosives on him when he was shot.

Police were actively looking for a second suspect (white hat in FBI photo), whom they described as armed and very dangerous.

"We are asking everyone to shelter in place for the time being, not to leave their homes, if they see something suspicious other than a police officer coming to their door, they should call 911 immediately," a police colonel said.

"We also want to forewarn motorists who are traveling through this area, that they should not stop for anyone and pick up anyone along the side of the roadway.

"What we are looking for now is a suspect consistent with the description of suspect number two, the white-capped individual, who was involved in Monday's bombing of the Boston Marathon.

Police said they had a photo of the suspect they're seeking, which was taken from a video at a 7-11 in Cambridge Thursday night. They described him as "a light-skinned or Caucasian male" with brown curly hair, wearing a gray hoodie sweatshirt.

"We have an active search going on by tactical teams to locate and apprehend this particular individual. He should be considered armed and dangerous and a threat to anybody that might approach him. So please, use extreme caution and stay in your homes."

Police did not give the suspects' names, saying they could not get into details.
