Investigations of the Boston Marathon bombings moved into day three Wednesday, but as the FBI uncovered more details about the explosive devices that killed three people and injured more than 176, there are no leads on suspects or motives.

Hundreds of investigators in Washington and Boston continued examinations of video and images of the race to try and piece together the attacks wtih facial recognition software.

“The range of suspects and motives remains wide open,” FBI Special Agent in Charge Richard Des­Lauriers said at a Boston news conference. 

"It's our intention to go through every frame of every video," said Boston Police Commissioner Ed Davis.

According to Businessweek, investigators recovered a piece of circuit board believed to be part of an explosive device used in the bombings, as well as the lid of a pressure cooker blown onto a rooftop. Authorities suspect the bombs were composed of pressure cookers packed with nails, ball bearings and other shrapnel. The new pieces of evidence could help investigators track the components and locate where the materials were purchased.

Georgia Senator Saxby Chambliss, the top Republican on the Senate Intelligence Committee, said initial evidence suggests domestic terrorism, but that officials can't say for certain.

The top Democrat on the House intelligence panel, Rep. Dutch Ruppersberger, said evidence so far point to acts of a "lone wolf," who worked "very quietly" with few others.

Authorities continue to investigate whether the bombs were constructed near the race, as transporting improvised explosive devices can trigger early detonation. The FBI continues to scan the area's hotels and short-term rentals for locations where the makeshift bombs could have been assembled.

Federal agents have further analyzed airplane passenger lists from flights into Boston's Logan airports, according to case officials.

Although the range of suspects remain "wide open," officials said it was not unusual for there to be no suspects at this stage of investigations.

DesLauriers continued to ask members of the public to submit any photographs or video they have from the blast site to help with the inquiry.
