On Monday, two identical pressure-cooker bombs that each had the capacity to hold six liters of liquid blew up seconds and a short distance apart on Boston's Boylston Street. The aftermath was devastating leaving three dead including an 8-year-old boy and 183 hospitalized. The wife of Sen. Angus King (I-ME) was in the marathon stands on Monday. This morning, King who serves as a member of the Intelligence Committee joins a special edition of “Starting Point” to weigh in on the latest regarding the Boston Marathon attack.
Currently officials are “tracing leads all over the place” says King. He adds “that there are thousands of pictures out there right now and it’s probably on somebody’s iPhone and picture of the guy. The person who left the bomb.”
King says “we all have a role to play” in the investigation because a lot of evidence is going to come from phones, security cameras and pieces of the bombs.
Investigators are tracking down some two-thousand leads this morning in their search for information regarding the Boston Marathon bombings. There are also new reports this morning that Boston-area hospitals have released at least 100 of the 183 people injured in Monday's attack. New details about the lives of the three people killed including a Chinese graduate student who was studying at Boston University are coming out as well. This morning Congressman Patrick Meehan (R-PA) joins “Starting Point.” Meehan serves as the chair of the House Counterterrorism and Intelligence Subcommittee and was briefed about the Boston Marathon bombing on Monday.
Meehan says officials are “now understand what the bomb components may be.” He adds that experts were “able to verify not only that it was a pressure cooker” and that might lead to the next step of finding out what type of pressure cooker.
After that the trail would mean finding out where exactly the pressure cooker came from and “who may have purchased it.”
Meehan says “you really just have to let the facts and evidence tell you the story and follow those logically.”
29-year-old bombing victim Krystle Campbell's grandmother, Wilma says she will remember her granddaughter with love. “All my love she’ll be there forever. She’s in my heart. Always is,” says Campbell.

This morning Boston-area hospitals have released at least 100 of the 183 people injured in Monday's Boston Marathon attack. New information has also been released regarding the third person killed – a Chinese graduate student who was studying at Boston University. Dr. Arun Ramappa is an orthopedic surgeon at Beth Israel Deaconess Medical Center. He was at his office when he heard about the attack and went to the hospital voluntarily to help out. This morning he joins “Starting Point” to discuss what it was like in the operating room assisting the victims of the Boston Marathon aftermath.
When he arrived at the hospital Ramappa says it was unlike anything that he had ever seen due to the “number of very highly injured people who were coming into the emergency room… in a short span of time.”
Ramappa says there were a large number of blast injuries to the lower extremities which involves “the bone and the soft tissue of the legs.” He adds that there was shrapnel in many of the injuries “including metal pieces, nails BBs and ball bearing type objects.”
Although a tremendous number of nursing staff, surgeons, doctors were not at the hospital due to the holiday Ramappa says “Everyone just pulled together. Everyone stepped up.” He adds that many hospital staff members “showed up to the hospital voluntarily without being called. And so everyone came together as a team and worked together to help care for all these people.”

Here are some helpful tips that can help distinguish real charities from fake charities as many rush to donate to those who were affected by the Boston Marathon bombings.
President Obama says those responsible for bombing the Boston Marathon will not escape justice. The president spoke speaking Monday night at the White House where he promised to find out who was responsible for the attack and why. He also reached out to leaders in congress saying this is a time for unity among all Americans. This morning Homeland Security Committee member Rep. Peter King (R-NY) weighs in on the investigation.
King says “the investigation is going full speed ahead” and that officials are currently looking at the components of the bombs. He adds, “That there is somebody apparently being questioned.”
King who is a member of the Intelligence Committee says “there was no intelligence warnings that we know of” but officials are looking back to see if there is something they may have missed.
“I think it’s the type of investigation that can move very quickly” says King. He adds that with the bomb components, camera footage and questioning “we should be getting an answer sooner rather than later.”
On Monday Tom Beusse, the president of the USA TODAY Sports Media Group was running the Boston Marathon. About three minutes after he had completed the race twin explosions erupted near the finish line. Beusse estimates he was about 150 yards away. This morning he joins a special edition of “Starting Point” to discuss the smoke and the devastating aftermath.
Beusse says his experience during the bombings at Monday’s marathon was “crazy.” He adds that after the race he and other runners were “meandering along and the next thing you know these explosions took place. Everybody sort of panicked. Everybody knew immediately there was a problem.”
He describes smoke rising immediately above the buildings and says “it was clear it was a big explosion. The sound in itself sort of rumbled the ground.”
After the explosion Beusse says “The Boston police just gathered everybody. Took us immediately through the corral. Called it a crime scene and got us out of harm’s way.”
This morning the FBI is leading the investigation into the twin bombings at the Boston Marathon. Overnight federal, state and local agencies searched an apartment in Revere, Massachusetts for possible clues. Although they left with bags of evidence, there is no word on any arrests. The attack which occurred on Monday left three people dead and over 150 people wounded. This morning the Chairman of the House Homeland Security Committee, Congressman Mike McCaul from Texas joins “Starting Point” to weigh in on the latest with the investigation.
Regarding the twin explosions McCaul says “we really didn’t have any” good intelligence in this case. He adds “there wasn’t a whole lot of chatter so we don’t know if this was a lone wolf type of plot or not.”
“It’s very hard to secure an open gathering like this whether it be a marathon, a football stadium, a shopping mall if you don’t have that … good intelligence beforehand,” says McCaul.
Washington and New York are “under heightened state of alerts right now” says McCaul. He adds that there is a significant amount of discussion among European counterparts in the event that the attack was “a foreign terrorist plot.”
