Remarks of Special Agent in Charge Richard DesLauriers at Press Conference on Capture of Bombing Suspect

It seems like many months since Monday, April 15, the day of the Boston Marathon bombings. Yet, it has merely been five days since the tragic explosions that took three lives, critically injured over 180 spectators, and instilled terror and fear among the citizens of the city of Boston, the Commonwealth of Massachusetts, and elsewhere.

Today, the city of Boston, the city of Cambridge, and the city of Watertown—and many other communities—can breathe a sigh of relief knowing that two perpetrators who caused so much pain and anguish are no longer a threat to our personal safety and our communities. More

2011 Request for Information on Tamerlan Tsarnaev from Foreign Government

In early 2011, a foreign government asked the FBI for information about Tamerlan Tsarnaev. The request stated that it was based on information that he was a follower of radical Islam and a strong believer, and that he had changed drastically since 2010 as he prepared to leave the United States for travel to the country’s region to join unspecified underground groups.

In response to this 2011 request, the FBI checked U.S. government databases and other information to look for such things as derogatory telephone communications, possible use of online sites associated with the promotion of radical activity, associations with other persons of interest, travel history and plans, and education history. The FBI also interviewed Tamerlan Tsarnaev and family members. The FBI did not find any terrorism activity, domestic or foreign, and those results were provided to the foreign government in the summer of 2011. The FBI requested but did not receive more specific or additional information from the foreign government. More

Remarks of Special Agent in Charge Richard DesLauriers at Press Conference on Bombing Investigation

Our collective law enforcement team has pursued thousands leads and tips. As I said two days ago, we are working methodically and with a sense of urgency to identify those responsible for the bombings. Within the last day or so, through that careful process, we initially developed a single person of interest. Not knowing if the individual was acting alone or in concert with others, we obviously worked with extreme purpose to make that determination...

More importantly, it was done to ensure the future safety of the city, the commonwealth and the country. Indeed, through that process, the FBI developed a second suspect.

Today, we are enlisting the public’s help to identify the two suspects.

After a very detailed analysis of photo, video, and other evidence, we are releasing photos of the two suspects. They are identified as Suspect 1 and Suspect 2. They appear to be associated. More

No Arrest Made in Bombing Investigation

Contrary to widespread reporting, no arrest has been made in connection with the Boston Marathon attack. 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.

Remarks of Special Agent in Charge Richard DesLauriers at Press Conference on Bombing Investigation

Let me recap our efforts in this investigation.

Yesterday at this time, our collaborative efforts were focused on saving lives and treating the injured. At the same time, resources were directed to ensure the safety of our community.

As soon as those important tasks were completed, first responders focused on establishing a criminal investigation. The FBI Boston’s Joint Terrorism Task Force, composed of more than 30 federal, state, and local law enforcement agencies, including Boston Police, Massachusetts State Police, and ATF, HSI, United States Secret Service, and others responded to the scene. Many of them were already there as part of the general security for the marathon already in place.

The first step law enforcement took was to secure the physical area around the blast for the purpose of preserving evidence in the area related to the devices itself. This morning the FBI, along with Boston PD, Massachusetts State Police, and ATF officially began its forensic evidence recovery effort at the site. Their goal was to recover physical items related to the blast. Those items have been recovered and sent to the FBI’s Laboratory in Quantico, Virginia. There, specialized examiners will reconstruct the device and determine its makeup and components. Among items partially recovered are pieces of black nylon—which could be from a backpack—and what appear to be fragments of BBs and nails possibly contained in a pressure cooker device. We are expediting this blast evidence to our Laboratory in Quantico, Virginia for a complete and thorough analysis. More
