Police have been seen carrying several large bags from a suburban Boston apartment that authorities say was searched in connection to the Boston Marathon bombing.
Boston area television stations are reporting that the bags were removed from an apartment in Revere, Mass., just north of Boston at about 2 a.m. Massachusetts State Police confirm that a search warrant was served Monday night, but have provided no further details.
The Revere Fire Department wrote on its Facebook page that firefighters responded to the scene for a search for "a person of interest."
The FBI is leading the investigation into the explosions, which killed three people and injured more than 140. Officials said the crime scene will be locked down for another day or two, allowing investigators to finish gathering evidence and follow up on leads.
According to the FBI, there are no other known threats in the Boston area.
Congressman Stephen Lynch, a friend of the family, says 8-year-old Martin Richard was among the three people killed in the explosions Monday. The boy's mother and sister were badly injured.
Lynch says the family had gone to get some ice cream and then to the finish line to watch some friends cross. He describes them as a strong family and says they're doing better than expected.
A candle burned on the stoop of the family's single-family home in the city's Dorchester section, and the word "Peace" was written in chalk on the front walkway. A child's bicycle helmet lay overturned on the front lawn.
Hospitals report that they are treating at 144 people Tuesday morning. Of those, at least 17 are in critical condition.
Police were inside a home in a suburb of Boston Monday night and Tuesday morning, gathering evidence in connection to a "person of interest." FBI agents along with Boston Bomb Squad officers and K-9 units emerged with a large plastic bag early Tuesday morning. They stress that the search was not tied to an actual suspect in the case.
President Barack Obama said authorities did not know who carried out the attack but vowed to render “the full weight of justice” against those responsible. Minutes later, law enforcement officials said that an 8-year-old child was one of the dead.
Video from the scene showed two blasts about 20 seconds apart just off the course at the finish. White smoke rose, barriers flew, and throngs of people who had gathered to cheer the runners fled in terror. They later reported seeing horrific injuries that included blown-off limbs and bodies thrown to the asphalt.
“All the sudden there was a massive boom. There was a sort of concussive blow that pushed a lot of people back. I could see runners falling in front of me,” said Dave Abel, a reporter for The Boston Globe who was 10 feet from one of the explosions.
“When the smoke started to clear, I could see lots of bodies,” he said. “I could see one woman staring vacantly into the sky. I could see a lot of mangled limbs, a lot of blood and shattered glass. It was probably the most horrific thing I’ve ever seen.”
Larissa Brinkley, who came from Pennsylvania to run the race, said people dropped everything and ran the opposite way. Other witnesses described what at first sounded like a cannon blast or fireworks.
“Then it went off again. And then all of a sudden we heard people crying and running away,” said Serghino Rene, who was a few blocks away. “It was a huge horde of people just running away.”
Federal officials told NBC News that Boston police were guarding a “possible suspect” who had been wounded in the blasts, but they cautioned that there was no information at the federal level to consider that person a suspect. Other people were being questioned, law enforcement officials said.
A third, undetonated device was found near the finish line, a House Homeland Security Committee official and three law enforcement officials told NBC News. Authorities also reported an explosion at the John F. Kennedy presidential library, elsewhere in the city, more than an hour after the blasts, but police said that it appeared to be caused by a fire. The police commissioner urged people to stay inside.
Hospitals reported that at least two children were among the injured. Dr. Alisdair Conn, chief of emergency medicine at Massachusetts General Hospital, characterized the wounds as something Americans are more accustomed to seeing on the news from a military-style bombing in Iraq or Israel.
“We still do not know who did this or why, and people shouldn’t jump to conclusions before we have all the facts, but make no mistake, we will get to the bottom of this,” Obama said from the White House several hours after the blasts. “Any responsible individuals, any responsible groups will feel the full weight of justice.”
He pledged the full help of the federal government and said: “The American people will say a prayer for Boston tonight.”
Suspicious packages were found after the blasts at three Boston subway stops, and authorities were investigating. New York police deployed extra security to landmarks, Pennsylvania Avenue in front of the White House was closed to foot traffic, and the Pentagon tightened security. Federal authorities briefly grounded flights at the Boston airport as a precaution.
Many, around the world, are following the situation via social media. WOWT has received Facebook messages on a handful of local runners. We're told from friends and family that Anthony Schutz, a professor at the University of Nebraska College of Law, Katie Swanson, Stan and Laura Kapustka, Mark Treadway, and Kim Moore all crossed the finished line and are okay.
