Day After ‘Act of Terror,’ Investigators in Boston Search for Clues

PBS NewsHour will live stream briefings and press conferences from Boston and the White House in the player above. Check back all day for updates.

2:29 p.m.: The Associated Press has identified 29-year-old Krystle Campbell of Medford, Mass., as one of the three people killed in the bombing at the Boston Marathon.

William Campbell told the AP that his daughter was a “very caring, very loving person, and was daddy’s little girl.” He said the loss has devastated the family.

Boston.com reports Krystle Campbell “went to watch the Marathon every year and was there with a friend this year. The friend is hospitalized with serious injuries.”

Martin Richard, 8, was also killed in Monday’s explosion. His father Bill Richard released a statement Tuesday. Richard’s wife Denise and 6-year-old daughter Jane also suffered significant injuries in the blasts:

“My dear son Martin has died from injuries sustained in the attack on Boston. My wife and daughter are both recovering from serious injuries. We thank our family and friends, those we know and those we have never met, for their thoughts and prayers. I ask that you continue to pray for my family as we remember Martin. We also ask for your patience and for privacy as we work to simultaneously grieve and recover. Thank you.”

The third victim has not yet been identified.

12:54 p.m. ET: The Associated Press reports:

The explosives used in the deadly Boston Marathon bombing were contained in 6-liter pressure cookers and hidden in black duffel bags on the ground, a person briefed on the investigation told The Associated Press on Tuesday.

One of the explosives contained shards of metal and ball bearings, and another contained nails, the person said.

A second person briefed on the investigation confirmed that at least one of the explosives was made out of a pressure cooker. Both spoke on condition of anonymity to discuss an ongoing investigation.

12:32 p.m. ET: Doctors in Boston described objects “clearly designed to be projectiles” removed from patients injured in Monday’s Marathon explosions.

The Boston Herald reports: “There’s no question some of these objects were implanted in the device for the purpose of being exploded when the device went off,” said Dr. Ron Walls, Brigham & Women’s chair of emergency medicine.

Walls described “ball-bearing type” objects, “just a little larger than a BB,” metallic beads about two to three millimeters in diameter. Surgeons also removed more than a dozen small “carpenter-type nails” about a centimeter to an inch in length from one patient, he said.

The Boston Globe:

“My opinion is that most of them were in the bomb,” said Dr. George Velmahos, trauma chief at Massachusetts General Hospital. “I think it’s unlikely they would be so consistent if they were pulled out from the environment.”

Dr. David P. Mooney, Boston Children’s Hospital trauma director, described deep shrapnel wounds in a 10-year-old being treated there who is in critical condition.

At Boston Medical Center, Dr. Andrew Ulrich said the shrapnel “could be described as buckshot.”

12:21 p.m. ET: The Associated Press, citing a person briefed on probe: Boston explosives made of pressure cookers with metal, ball bearings.

12:06 p.m. ET: In an appearance Tuesday morning at the White House, President Barack Obama called Monday’s bombings at the Boston Marathon an “act of terror,” but said it is not clear whether the twin blasts were the work of a foreign or domestic group or a “malevolent individual.”

The two explosions have killed at least three people and wounded more than 170.

The Associated Press reported that Dr. Stephen Epstein of the emergency medicine department at Beth Israel Deaconess Medical Center said he saw an X-ray of one victim’s leg that had “what appears to be small, uniform, round objects throughout it — similar in the appearance to BBs.”

On Capitol Hill, Defense Secretary Chuck Hagel called the bombings “a cruel act of terror” and said “a thorough investigation will have to determine whether it was planned or carried out by a terror group, foreign or domestic.”

Richard DesLauriers, the FBI agent in charge in Boston said, “We will go to the ends of the Earth to identify the subject or subjects who are responsible for this despicable crime, and we will do everything we can to bring them to justice.” He said investigators had received “voluminous tips” and were interviewing witnesses and analyzing the crime scene.

Massachusetts Gov. Deval Patrick said that contrary to earlier reports, no unexploded bombs were found. He said the only explosives were the ones that went off.

FBI agents searched a home in the suburb of Revere, Mass., overnight, the Associated press reported. Authorities gave no details, but investigators were seen leaving a building there early Tuesday carrying brown paper bags, plastic trash bags and a duffel bag.
