Boston Suspects- Graphic

Dzhokhar Tsarnaev, on the run; Tamerlan Tsarnaev, dead

(CNN) — The manhunt for the suspect in Monday’s marathon bombings has led officials to shut down transportation, hospitals and other services throughout the city of Boston and its suburbs. Among them:

• Around 6 a.m., the Massachusetts Bay Transit Authority tweeted that all “modes” of transport — including rail, subway, buses and ferries — would be suspended until further notice. Later, the authority tweeted, “Please DO NOT Wait at Bus and Station Stops.”

• The MIT campus, where a university police officer was killed, said that all classes were canceled. “All employees are encouraged to use their best judgment about whether they are prepared to come in to work today: any absence today will be considered excused. MIT is working now to plan a gathering later today on campus. Once we have determined the time and place, we will communicate with you all,” a statement said.

• Harvard later did the same, announcing, “In consideration of the manhunt that is underway, we are asking members of the Harvard community to remain home from work and classes today.” Boston Public Schools also followed suit, announcing that all system functions, including administrative offices and family resource centers, would be canceled.

• While police requested residents of Boston and all its suburbs remain at home, the Massachusetts State Police specifically singled out Boston, Watertown, Cambridge, Allston Brighton, Belmont and Newtown. The governor’s office added Waltham to the list of places where the people should “stay indoors with your doors locked.”

• Later, the Boston Police Department would announce that “all vehicle traffic” in Watertown was suspended. The department also announced on Twitter that “all taxi service in the city of Boston has been suspended,” though the department announced taxi service was restored shortly before 11 a.m.

• The Federal Aviation Administration ordered a 3.5-nautical-mile temporary flight restriction over Boston “to provide a safe environment for law enforcement activities.” The restriction is from surface to 3,000 feet, according to the FAA. Amtrak also suspended service between Boston and Providence, Rhode Island.

• Boston’s Logan International Airport is operating normally under heightened security, according to airport spokesman Matthew Brelis. “It’s open and operating and flights are operating,” he said. “Airlines are waiving fees for passengers who don’t want to or can’t fly today. … Taxis are coming and going. Call your airline for your flight status before you leave for the airport, which is what we say anyway, but allow yourself a little extra time.”

• Massachusetts General Hospital was on lockdown, with just one entrance open, said Kory Zhao with the press office. Access was limited to doctors and staff members with identification; patients ready for discharge were being advised to stay put.

• Brigham and Women’s Hospital was on total lockdown, said Jess Maki of corporate communications. So, too, was Boston Medical Center, said Gina DiGravio, the media relations manager.

At Beth Israel, “business is proceeding as usual” within the confines of the city, which itself was on lockdown, said Bonnie Prescott of the communication office.

• At Tufts Medical Center, Julie Jette, director of media relations and publications, said “minimum entrances” were remaining open. “Services are available for patients who need them.”

• At St. Elizabeth’s Medical Center and Steward Hospital Services, operations were on lockdown, meaning that elective surgeries and visitor access were canceled, but emergencies were being treated, said marketing director Jennifer Kovalich.

• Boston Children’s Hospital’s main campus in the Longwood Medical Area was locked down, meaning that patient appointments were canceled and patients would not be discharged, said Rob Graham, director of media relations and national strategy.

• Boston Children Hospital’s Waltham facility and its Martha Eliot Health Center in Jamaica Plain were closed.

• But six miles south of the focus of police activity, operations were continuing as normal at Lemuel Shattuck Hospital, an operations manager told CNN.

Authorities search for bombing suspect in Watertown

Law enforcement personnel comb the neighborhood of Watertown, Massashusetts on April 19, 2013 for Dzhokhar Tsarnaev, the second suspect in the Boston Marathon bombings..

BOSTON (CNN) — The suspects involved in the Boston Marathon bombing were brothers from the Russian Caucasus who moved to Kazakhstan before coming to the United States several years ago, a source briefed on the investigation told CNN.

One of the brothers, identified by several sources as Tamerlan Tsarnaev, 26, studied engineering at Bunker Hill Community College but had taken off a year to train as a boxer, the source said Friday.

The source said a posting on a social media website under his name included the comment: “I don’t have a single American friend. I don’t understand them.”

He died at a hospital overnight after a gun battle with police, authorities said. A source briefed on the investigation says Tsarnaev was wearing explosives and an explosive trigger when his body was recovered.

Several sources identified the other brother, who remained on the lam, as Dzhokhar Tsarnaev, 19.

The source briefed on the investigation added that it should not be assumed that the brothers were radicalized because of their origins in the Russian Caucasus.

The spokesman for Chechen President Ramzan Kadyrov said the brothers had not been connected with the Chechen Republic for many years, Russia’s semi-official Interfax news agency reported Friday.

“According to preliminary information, coming from the relevant agencies, the Tsarnaev family moved many years ago out of Chechnya to another Russian region,” press secretary Alvi Kamirov told Interfax. “After that they lived for some time in Kazakhstan, and from there went to the U.S. where the family members received a residence permit. Therefore the individuals concerned did not live as adults in Chechnya.”

An official in the central Asian republic of Kyrgyzstan told CNN that the brothers were Kyrgyz passport holders, and used those passports when applying for green cards in the United States.

Many refugees from the Caucasus conflict received passports or refugee status in surrounding countries.

Two sources told CNN Dzhokhar Tsarnaev came to the U.S. as a tourist with his family in the early 2000s and later asked for asylum. He became a naturalized U.S. citizen in 2012. Tamerlan Tsarnaev was not a naturalized citizen. He came “a few years later” and was lawfully in the United States as a green-card holder.

A leader of the ethnic Chechen community in Kyrgyzstan told CNN that the Tsarnaev family left the republic more than a decade ago.

“There haven’t been any Tsarnaev’s living here in 10 or 15 years,” said Adnan Djubrailov, in a phone call from Kyrgyzstan.

Dzhokhar Tsarnaev had worked as a lifeguard at a pool at Harvard University, said George McMasters, who hired him about two and a half years ago and said he was impressed with his work ethic. “He showed up on time, he watched the water, he rotated from position to position fine, got along well with others.”

McMasters, who is the aquatic coordinator, said Tsarnaev gave no clue to a violent side. “He seemed like a very quiet, unassuming young man,” he said. “It is very surprising and shocking to see the destruction that he has brought to the city.”

Last year, McMasters was deployed to Afghanistan with the Army National Guard and, when he returned to the job in August, Tsarnaev was no longer on the staff or the schedule, he said.

Dzhokhar Tsarnaev attended Cambridge Rindge & Latin, a public high school, said friend Eric Mercado, who graduated a year behind the suspect.

“We hung out; we partied; we were good high school friends,” Mercado told CNN.

“We’re all, like, in shock. We don’t really understand. There were no telltale signs of any kind of malicious behavior from Dzhokhar. It’s all coming as a shock, really.”

Mercado said he lived a block away from the suspect and had not known his older brother.

“To think that he’s capable of something like this is beyond belief,” Mercado said. The younger brother was registered at the University of Massachusetts-Dartmouth, which ordered its campus evacuated on Friday. The school is located 65 miles south of Cambridge, just west of New Bedford.

Larry Aaronson, a former teacher at Cambridge Rindge & Latin who lives near Dzhokhar Tsarnaev’s residence in Cambridge, said he had taken pictures of the younger brother wrestling. “There is nothing in his character, in his deportment, in his demeanor that would suggest anything remotely capable of any of these things that he is now suspected of doing,” Aaronson told CNN.

“He was so grateful to be here, he was so grateful to be at the school,” he said. “He was compassionate, he was caring, he was jovial.”

He described the suspect, whom he last ran into in the neighborhood a few weeks ago, as “a lovely, lovely kid.”

The other brother, Tamerlan Tsamaev, was listed as a participant in the 201-pound class in a Salt Lake City 2009 Golden Gloves event.

Ruslan Tsarni, a Maryland man who said he was an uncle of the suspects, had no sympathy for them and no regret that his elder nephew was killed. “Good,” he told CNN affiliate WBZ. “He got what he deserved.”

Tsarni said Tamerlan Tsarnaev came to the United States as a child in 2000 or 2001, and that he last saw him in 2005 or 2006. “He’s really been a quiet, nice boy,” he said.

In all, 176 people were treated at area hospitals after the blasts, with 17 in critical condition, Police Commissioner Davis told reporters a day after the blasts. It was not clear if he was including the fatalities.

The bombings resulted in at least 10 amputations and left doctors picking ball bearings out of victims in the emergency room, a terrorism expert briefed on the investigation said.

Some patients had been struck with metal beads slightly larger than BBs, Dr. Ron Walls from Brigham and Women’s Hospital said. And doctors removed more than a dozen small nails from one patient, he said.

While the nation waits to hear if police have identified any suspects in the bombing at the Boston Marathon, news agencies are reporting that investigators are working leads provided by private video cameras — either owned by businesses or tv stations.

They are the kind of cameras that are becoming more and more common.  This week, they’re credited for possibly helping the Boston investigation.  Next week, it could be something else, somewhere else.

“People’s homes, people’s businesses, and chances are it’s going to catch something bad like this when it happens,” said Bryan Legard, the president of the CCTV security company.  Legard also operates the Project NOLA network of security cameras.

No doubt, cameras are becoming more common.  But not everyone is on board with their proliferation.

Already the debate is underway regarding the use of drones with cameras for surveillance purposes.  Not only are the federal as well as state and local governments around the country using or considering the use of the drones, the high-tech machines are available at malls for the general public to buy and fly.  At least one of the more popular consumer models includes a high-definition camera that allows its pilot to record video on a cell phone or tablet.

The ACLU is also on record for expressing concerns over the expanding use of cameras, saying it is a potential threat to privacy.

But when the cameras in question could help solve the nation’s latest terror attack on American soil, few people are ready to complain about their use.

“There really isn’t much question left.  You have a picture of that person doing that with the harmful device. How are you going to say that wasn’t you?” Lagarde said.
