INVESTIGATION: There were conflicting reports in the early afternoon about whether a suspect was or was not in custody. As of 2:15 p.m. ET, sources with knowledge of the investigation were telling NPR’s Tom Gjelten that an arrest had not yet been made.

Law enforcement is expected to brief reporters later tonight.

Tom reports that a senior law enforcement official told him that authorities have reviewed video of a man setting down a bag and leaving the scene, but that does not necessarily make him a suspect. “We need more than that,” the official said.

CNN’s Deb Feyerick said what they know is the FBI has a picture of a suspect. What’s unknown is whether they’ve even identified the suspect.

NPR’s Dina Temple-Raston reports that an official familiar with the investigation told her the bomb was “a pressure cooker design with nails and ball bearings inside.” And Dina that FBI investigators thought the key clue to finding who’s responsible would come from a photo or video taken by a spectator — evidence that “people don’t know is important, but the FBI looks at and sees some clue.” , officials posted this appeal for help: “If you have any information that could be of assistance, please call 1-800-CALL-FBI (prompt #3). No detail is too small.”

DEATHS, INJURIES: The three people who were killed have been identified: and from suburban Dorchester. and lived in Medford, Mass. was a graduate student at Boston University.

NPR’s Dina Temple-Raston reports that an official familiar with the investigation told her the bomb was “a pressure cooker design with nails and ball bearings inside.” And Dina that FBI investigators think the key clue to finding who’s responsible may come from a photo or video taken by a spectator — evidence that “people don’t know is important, but the FBI looks at and sees some clue.” , officials have posted this appeal for help: “If you have any information that could be of assistance, please call 1-800-CALL-FBI (prompt #3).

About 180 people were injured. , just two of those being treated at Boston Medical Center remained in “critical condition.” CNN was reporting that about 100 people had been allowed to go home. Related post on the Shots blog: “.”

Update at 1:20 p.m. Suspect Seen On Video?

that “investigators believe they have identified a suspect in the Boston Marathon bombings, a source who has been briefed on the investigation told CNN’s John King exclusively.” They told CNN that videos taken at the scene helped them zero in on the individual. s it has been told by a source that “authorities have an image of a suspect carrying, and perhaps dropping, a black bag at the second bombing scene.” Authorities are set to brief reporters at 5 p.m. ET.

Update at 1:10 p.m. ET. Third Person Identified:

that the third person killed was “Lingzi Lu … a graduate student in mathematics and statistics.” that she “was a native of Shenyang, a city in northeastern China about a hundred miles from the North Korean border. She attended Shengyang Northeastern High School, from which she graduated in 2008. She did well enough there to land a spot at the Beijing Institute of Technology, where she pursued a bachelor’s degree in international economics. In Boston, she had hoped to obtain her master’s. On Monday afternoon, Lu joined the marathon-watchers with two other overseas Chinese friends, partaking in one of their first and more cacophonous of American traditions.”

Update at 12:35 p.m. ET. “Significant” Progress?

CNN is reporting it has been told by authorities that “significant” progress has been made today on the investigation.

Update at 10:20 a.m. ET. Comparison To Vancouver Riot Investigation:

Following ago when the NHL’s Canucks lost the Stanley Cup championship, authorities requested photos and videos taken by the public to help find those who had set fires and thrown gasoline bombs. , correspondent David Boeri said more than 1 million photos were submitted and “1,200 to 1,600 hours of video.” In large part because of that evidence, police “were able to determine who had thrown bombs” and were responsible for other misdeeds.

Boeri said authorities in Boston are hoping the huge amount of evidence that’s likely in photos and videos taken by spectators and the media will help solve the marathon bombings.

Reminder: , officials have posted this appeal for help: “If you have any information that could be of assistance, please call 1-800-CALL-FBI (prompt #3). No detail is too small.”

Update at 8:45 a.m. ET. Patients Improving, Doctor Says:

Most of the 10 or 11 victims being treated at Boston Medical Center who were initially in critical condition have made good progress, chief trauma surgeon Dr. Peter Burke just told reporters. He said only two patients remain in critical condition, and he expects them to survive their injuries. Burke added that 10 patients at the hospital are now considered to be in “serious” condition. An additional seven are said to be in “fair” condition.

Update at 8:15 a.m. ET. Mass. Governor Expects “Long, Painstaking Investigation”:

No “specific suspect or targets” have yet been identified, Massachusetts Gov. Deval Patrick (D) . And while “every hour, every day” brings investigators “a little closer” to finding out who was responsible, Patrick said everyone needs to “settle down and settle in for a long, painstaking investigation.”

“This is the kind of investigation that requires picking up tiny pieces [of evidence] and scouring blocks … a square inch at a time,” the governor added.

Update at 8:05 a.m. ET. Pressure Cooker Lid Found?

 

CNN is reporting that the lid of a pressure cooker has been found on the roof of a building near the site of Monday’s explosions.

Update at 8 a.m. ET: 100 Of The Injured Released, CNN Reports:

The latest estimate on how many people were injured, CNN says, is 183. And of those, about 100 are out of the hospital, the news network adds.

Note: As happens when stories such as this are developing, there will likely be reports that turn out to be mistaken. Monday, for example, authorities at one point said they thought there also had been an explosion at the JFK Library in Boston. But it turned out there had been a fire, not an explosion, and there’s no known link at this time to the marathon attacks.

We will focus on news being reported by NPR, other news outlets with expertise, and statements from authorities who are in a position to know what’s going on. And if some of that information turns out to be wrong, we’ll update.
