It’s a scene of carnage at the finish line of the Boston Marathon.   Officials said two bombs that exploded near the end of the race were about 100 yards and 10 seconds apart.

The shock waves brought bystanders to the ground, shattered windows and sent plumes of smoke into the air.

Tom Meagher, a Boston Marathon official, describes what he saw when the first bomb detonated.

The scene of Monday’s massacre is being described as the most complex crime scene Boston police have ever seen.  Boston Police Commissioner Ed Davis said Tuesday morning that they’re processing the scene under the guidance of the FBI and ATF. He added that the National Guard is securing the scene, and that the cordon has been reduced from 15 blocks to 12.

Seventeen people remain in critical condition. Davis remarked that the latest assessment is more than 170 people wounded in the blasts.  Three people are dead.  A doctor at Massachusetts General Hospital said nails and pellets are being removed from the bodies of victims. Dr. George Velmahos said the bombs inflicted severe trauma in some victims, resulting in amputations. He added that all the victims being treated at Mass Gen are alive and stable.

A massive investigation is in full swing.  Federal agents and Boston police swarmed an apartment complex in Revere, Massachusetts late Monday night.  Several bags of items were taken out of the apartment, but police have been tight-lipped on the search and seizure.

New details were released during an 8:30 a.m. news conference on Tuesday.  The FBI agent in charge of the investigation said the agency’s mission is clear: to bring those responsible to justice. Special Agent-in-Charge Richard DesLauriers said there’s still an active investigation.  He added that Bostonians should expect to see law enforcement personnel in action in the greater Boston area.

Massachusetts Governor Deval Patrick said no unexploded bombs have been found at the scene.  In the press conference, Patrick said Bostonians should expect security to remain high.

Mayor Tom Menino remarked that Boston is a close-knit community, and the city mourns for the three people killed in the attack.

Many high profile officials responded in the wake of the bombings.  In remarks Monday night, President Obama cautioned against jumping to conclusions about who was responsible or why.  He vowed to “find out who did this” and “hold them accountable.”  Obama added that those responsible will face the “full weight of justice.”  Obama and authorities stopped short of calling it a terror attack.

China offered its condolences and condemned the bombings.  A foreign ministry spokeswoman told reporters that China strongly condemns and is firmly opposed to any attack aimed at common people.

Pope Francis issued a message of hope to the Archdiocese of Boston on Tuesday morning.  In a telegram to Cardinal Sean O’Malley, the Vatican’s Secretary of State said Pope Francis was “grieved” by the loss of life and injuries caused by what he called a “senseless tragedy.”  The Pope also urges all Bostonians to be, quote, “united in a resolve not to be overcome by evil.”

Police are urging anyone with pictures or video of the bombing or just the surrounding area at the time of the bombing to turn them over to police.
