Boston Marathon Explosions

Memphis - Two powerful bombs exploded near the finish line of the Boston Marathon on Monday afternoon, killing at least three people, including a child, and injuring at least 100 as one of this city’s most cherished rites of spring was transformed from a scene of cheers and sweaty triumph to one of screams, bloody carnage and death.

About three-quarters of the 23,000 runners who participated in the race had already crossed the finish line when a bomb that had apparently been placed in a garbage can exploded in a haze of smoke amid a crowd of spectators on Boylston Street, just off Copley Square in the heart of the city. It was around 2:50 p.m., more than four hours after the race had started, officials said. Within seconds, another bomb exploded several hundred feet away. 
Pandemonium erupted as panicked runners and spectators scattered, and rescue workers rushed in to care for the injured, some of whom had lost their legs in the blast, witnesses said. The reverberations were felt far outside the city, with officials in Washington heightening security on public transit and shutting down streets near the White House. Pennsylvania Avenue was cordoned off by the Secret Service in what one official described as “an abundance of caution.”  



In New York, the Police Department said it was stepping up security at hotels and other prominent locations in the city until more is learned about the explosion.

“The first one went off, I thought it was a big celebratory thing, and I just kept going,” recalled Jarrett Sylvester, 26, a marathon runner from East Boston, who said it sounded like a cannon blast. “And then the second one went off, and I saw debris fly in the air. And I realized it was a bomb at that point. And I just took off and ran in the complete opposite direction.”
In the chaotic hours after the explosions, according to a person briefed on preliminary developments in the investigation late Monday afternoon, there were reports of three unexploded devices. Police officials said at least one was detonated in a controlled explosion.
At their final briefing Monday night, officials said that the F.B.I. had taken over the investigation. Richard DesLauriers, the special agent in charge of the Boston office, called it “a criminal investigation that is a potential terrorist investigation.” But they offered no information on what they had found or what they were investigating except to say that they were bringing “very substantial federal resources” to bear.
It was unclear Monday evening who might be responsible for the blast. Although investigators confirmed that they were speaking to a Saudi citizen, several law enforcement officials took pains to note that no one was being held in custody.
While the authorities have not arrested the Saudi man, he has remained at a hospital under close supervision by law enforcement authorities, according to a senior law enforcement official.

By nightfall, the authorities were acting on the belief that there had only been two explosive devices. As a precaution, the authorities had blown up several bags — which they believed were likely left by marathon runners — that were on the streets near the attacks.
The explosive devices used in the attacks on Monday were similar in size to the device used in the 1996 attack at the Centennial Olympic Park Bombing in Atlanta but were not nearly as large as the one used in the 1995 attack in Oklahoma City. In the Atlanta attack, a pipe bomb was detonated near pedestrians, killing two and injuring more than 100 — similar numbers to Monday’s attack.
The attack in Oklahoma City was far larger because the perpetrator used a truck packed with thousands of pounds of explosives. The device killed more than 150 people.
The attack on Monday occurred in areas that had been largely cleared of vehicles for the marathon. Without vehicles to pack explosives into, the perpetrators would have been forced to rely on much smaller devices.

Officials took pains to stress that they had no suspects in the attack. The Saudi man, who was interviewed at Brigham and Women’s Hospital, had been seen running from the scene of the first explosion, a person briefed on preliminary developments in the investigation said on Monday afternoon. A law enforcement official said later Monday that man, was in the United States on a student visa and came under scrutiny because of his injuries, his proximity to the blasts and his nationality — but added that he was not known to federal authorities and that his role, if any, in the attack, was unclear.
The deadly explosions brought life in Boston to a halt. Police officials effectively closed a large swath of the Back Bay neighborhood, which surrounds the blast site; some transit stops were closed; planes were briefly grounded at Boston Logan International Airport and the Boston Symphony Orchestra canceled its Monday night concert. A Boston Celtics game scheduled for Tuesday was canceled.
Boston was bracing for a heightened law enforcement presence on Tuesday, with its transit riders subject to random checks of their backpacks and bags, and many streets in the center of the city likely to be closed to traffic as the investigation continues. Gov. Deval Patrick said Monday night that “the city of Boston is open and will be open tomorrow, but it will not be business as usual.”
Boston’s police commissioner, Ed Davis, urged people to stay off the streets. “We’re recommending to people that they stay home, that if they’re in hotels in the area that they return to their rooms, and that they don’t go any place and congregate in large crowds,” he said at an afternoon news conference.
It had begun as a perfect day for the Boston Marathon, one of running’s most storied events, with blue skies and temperatures just shy of 50 degrees. The race typically draws half a million spectators. And long after the world-class runners had finished — the men’s race was won by Lelisa Desisa Benti of Ethiopia, who finished it in 2 hours, 10 minutes and 22 seconds — the sidewalks of Back Bay were still thick with spectators cheering on friends and relatives as they loped, exhausted, toward the finish line.
Dr. Natalie Stavas, a pediatric resident at Boston Children’s Hospital, was running in the marathon with her father and was nearing the finish line when the explosions shook the street.
“The police were trying to keep us back, but I told them that I was a physician and they let me through,” she recalled in an interview.
First she performed CPR on a woman lying on the ground. “She was on the ground, she wasn’t breathing, her legs were pretty much gone,” she said, adding that she feared that the woman had not survived.
Then she tried to help a woman with an injury in her groin area, and a man who had lost his foot in the blast. Dr. Stavas said that she applied a tourniquet to the man’s leg with someone’s belt. “He was likely in shock,” she said. “He was saying, ‘I’m O.K., doctor, I’m O.K.’ “
“Then ambulances started coming in by the dozen,” she said.
The blast was so powerful that it blew out shop windows and damaged a window on the third flood of the Central Library in Copley Square, which was closed to the public for Patriots’ Day.
A number of people were taken to Massachusetts General Hospital, said Dr. Alasdair Conn, the hospital’s chief of emergency services — and several had lost their legs.
“This is like a bomb explosion we hear about in Baghdad or Israel or other tragic points in the world,” Dr. Conn said, adding that he had never seen such carnage in Boston.
Several children were among the 10 patients who were brought to Boston Children’s Hospital, including a 2-year-old boy with a head injury who was admitted to the medical/surgical intensive care unit.
The police faced another problem as they tried to secure the blast scene: many spectators dropped their backpacks and bags as they scattered to safety, and investigators had to treat every abandoned bag as a potential bomb. There were bomb scares at area hotels. At one point in the afternoon, Boston police officials said that they feared that a fire at the John F. Kennedy Presidential Library and Museum could have been related to the marathon bombs, but they later said it they seemed to be unrelated.
The Boston police said that they were getting numerous reports of suspicious packages. Asked if they had found all the explosive devices, Mr. Davis, the police commissioner, urged citizens to remain alert and said he was “not prepared to say we’re at ease at this time.”
