(USA TODAY) -- Investigators reported major progress in the Boston Marathon
bombing case Wednesday, but said no arrest had been made, despite
conflicting news accounts.
"Contrary to widespread reporting, there have been no arrests
made in connection with the Boston Marathon attack," the FBI said in a
"Over the past day and a half, there have been a
number of press reports based on information from unofficial sources
that has been inaccurate. Since these stories often have unintended
consequences, we ask the media, particularly at this early stage of the
investigation, to exercise caution and attempt to verify information
through appropriate official channels before reporting."
The Associated Press and CNN had reported earlier that a suspect had been taken into custody.
As media reports spread of a possible arrest, Boston's federal courthouse was jammed with a massive police
and media presence and scores of specators. People with cell phone
cameras poised to snap a picture of any suspect filled the parking lot.

flatly: "Despite reports to the contrary, there has been no arrest." The
message added that officers should "remain diligent in our mission."
reports that officials were zeroing in on a possible suspect came as
several news sources said investigators had identified images of a
suspect seen delivering one of the explosive devices near the marathon
CNN's John King quoted law enforcement
sources as saying that surveillance video from a nearby Lord &Taylor
department store was key in the investigation. Television footage also
played a role, CNN reports.
"The camera from Lord & Taylor is the best source of video
so far," said Dot Joyce, a spokeswoman for Boston Mayor Thomas M. Menino tells the Boston Globe. "All I know is that they are making progress."
A law enforcement official, who described the investigation as "very
active,'' told USA TODAY that authorities have been focusing on a mass
of photographic evidence provided by the public and area security
cameras. But the source indicated that there mixed views on the value of
the analysis so far.
"There is a lot going on," said the official, who is not authorized to comment publicly on the investigation.

from a pressure cooker believed used as one of the explosive devices, a
federal law enforcement official said.

The discovery came as the head of the Department
of Homeland Security told a Senate panel in Washington that the Coast
Guard worked with the Boston Police Department after Monday's bombings
to guard against any potential water-borne attack from Boston Harbor or
the Charles River.
Janet Napolitano said officials continue to investigate the bombing with the FBI as a solitary act of terror.
"There is no current indication to suggest the attack was indicative
of a broader plot," Napolitano told the Senate Homeland Security and
Governmental Affairs Committee. "But out of an abundance of caution, we
continue to keep in place enhanced security measures, both seen and
At least 12 of those injured in the blast remained in
critical condition Wednesday at several area hospitals. Peter Burke,
chief trauma surgeon at Boston Medical Center, said two of the 19
patients there still being treated remain in critical condition,
including a 5-year-old boy. All, however, are expected to survive, he
Burke said patients who required amputations or who lost
limbs at the bomb scene are now entering the second phase of their
recovery, which is making sure that infection does not set in. "They
get injured very quickly, but it takes a long time for people to get
better," he said.
At the blast site, evidence investigators from
ATF, FBI and other federal agencies wearing protective suits continued
poring over the crime scene Wednesday. Evidence trucks and mobile labs
fill Exeter Street, the side street off Boylston closest to the blast
The amount of gunpowder used in the Boston Marathon
bombings is believed to be a fraction of the overall weight of the
devices, estimated to be about 20 pounds each, a law enforcement
official said Wednesday.
Much of the weight was attributed to the
pressure-cooker container and a mix of shrapnel - BB pellets and nail
fragments -that cut a deadly path through the crowds gathered near the
race finish line, said the official who is not authorized to speak
The official said the components of the bomb - common
kitchen pressure cookers, wire, batteries and gunpowder - are so widely
available that barring the assistance of an informant or a telling photo
from the crime scene, it will likely take investigators some time to
determine where the materials were obtained and who acquired them.

identification of possible suspects, "and right now it's looking like
At the same time, the official said, bomb technicians will
likely be able to reconstruct much of the entire device, from both
pieces recovered from the scene and the collective knowledge of
investigators who have encountered similar devices in past
"They are going to be able to figure out how this
device was acquired,'' the official said. "Depending on the trade craft
involved, they will be able to do it relatively easily.''
FBI chief Richard DesLauriers said the recovered materials were being
examined at the FBI's laboratory in Quantico, Va., where the bureau has
assembled a clearinghouse of IED devices recovered from places ranging
from the battlefields of Iraq and Afghanistan to crime scenes around the
The scene is strewn with shredded T-shirts, metal fragments and glass
shards. Boston Police and National Guard soldiers guard every access
point, but from the side streets, spectators have watched the
investigators at work.
Some evidence is being flown to the FBI lab
and will undergo an expedited analysis, FBI spokesman Special Agent
Jason Pack said.
The ATF's evidence recovery experts have found
blast debris on rooftops and embedded in nearby buildings, Acting ATF
Special Agent Eugenio Marquez said.
"It gives the scope of the power of the blast," Marquez said.

videos and photos of the scene in hopes of getting an image of the
person or persons who left the explosive devices near the finish line of

bombings and are urging anyone with tips to come forward with
"The person who did this was someone's friend,
co-worker or neighbor," DesLauriers said. "Somebody knows who did this."
No one has claimed responsibility for the atrocity and "the range of
suspects and motives remain wide open."
