Faced with few overnight developments in the investigation of the bombings, the morning shows focused on the human impact of the explosions, interviewing eyewitnesses and victims that were at the marathon finish line.

On “Today,” Savannah Guthrie‘s interview with the President — which was taped before news of the bombings broke — was condensed due to NBC’s coverage from Boston. More of the interview will air later this week. In Boston, Matt Lauer did a number of interviews with victims of the attack, including one with a couple from a hospital room at Tufts Medical Center:

On “Good Morning America,” George Stephanopoulos anchored from Boston, joined by ABC’s Josh Elliott, Martha Raddatz and Brian Ross. Stephanopoulos interviewed a runner who crossed the finish line seconds before the first blast, and “GMA” used a spot-shadow to identify her in the video of the explosion: continued…

All three evening newscasts were expanded Monday after a pair of explosions killed at least two people at the finish line of the Boston Marathon.

The newscasts began shortly after President Obama addressed the nation from the White House press briefing room at 6:10pmET. NBC’s Brian Williams, ABC’s Diane Sawyer and CBS’ Scott Pelley had been anchoring coverage on their respective networks since the news broke shortly after 3pmET. ABC News and NBC News took brief breaks from their respective special reports just before the official start of the evening newscasts at 6:30pmET.

CBS News had Terrell Brown reporting from the scene and Don Dahler reporting from Massachusetts General Hospital. At the beginning of “Evening News,” correspondent John Miller took a few minutes to “clarify all these reports we’re seeing about a suspect in the media.” Saying he wanted to “proceed very carefully from here on out,” Miller reported that the person who was detained is a Saudi national who was seen running from the scene. “That may mean a lot, that may mean nothing at all,” Miller cautioned, noting that many people were running away from the blasts.

On NBC News, Williams was joined by Katy Tur in Boston, Chuck Todd from Washington D.C. and Pete Williams on the Boston police investigation. Williams interviewed an eyewitness, Serdar Ozturk, who saw the explosion from the finish line. “People’s faces instantly changed from smile to tears, and fear,” he told Williams. “People started running for their lives.”

ABC News had reports from senior national correspondent Jim Avila, senior Justice correspondent Pierre Thomas and Linsey Davis from the scene. Sawyer also checked in with Alex Perez in Chicago and Cecelia Vega in Los Angeles about security precautions in place in those two cities. “World News” ended with a montage of still photos from the scene. “We thank you so much for watching tonight,” Sawyer said. “Boston, as you know, is one of America’s great cities, filled with resilience and spirit. So on this day, when something terrible happened, we wanted to remind you of all those who rushed to help.”

All three networks have more extended coverage planned. Williams will anchor a special report at 10pmET on NBC, Terry Moran will anchor “Nightline” live at 12:35amET on ABC, and Pelley remained on the air with “Evening News” through 8pmET.

I have a TV in every single room of my house. I’m a big, big, big TV news junkie. I think it starts with my background in local news. I love the news. My DNA is very news driven and news oriented. I like Lori Stokes. I see her in the morning. She’s on ABC. At our place I like Terrell Brown. That’s my morning team that I tune into see. I like Scott Pelley for evening news because I’m a team player. I always like to see what we’re doing. I’m a big Anderson Cooper fan. I like to watch his show at night it’s really great to catch up on the day’s news with Anderson. He seems to cover all the bases, or certainly things I’m interested in, whether it’s a local story breaking news or national breaking news. I find I can get a lot out of his show. CNN is big for me, MSNBC is big, and during the campaign I was watching Fox because I was curious to see what they were saying.
