Crime scene photos first obtained by FOX 25's sister-station, FOX 5 Atlanta, are the first look at what is left of the first bomb that exploded at the finish line of the Boston Marathon.
Investigators have been sifting through remaining pieces of the bomb, hoping to draw a clear picture of how it was built, where it was built, and ultimately, who built it.
The Associated Press has reported that the device was a pressure cooker bomb -- common cookware throughout the world. The crime scene pictures obtained by the FOX 5 I-Team show pieces of a stainless steel pressure cooker with an Underwriters Laboratory number. One picture shows the imprint: Gas and Electric.
Another picture shows what appears to be a black, padded knapsack or duffel bag. Various news outlets have reported that the bomb was carried in a black bag.
Massachusetts General Hospital doctors described removing pellets and headless nails from the bodies of bombing victims. Both doctors and federal agents believe the shrapnel was included to make the bomb deadlier. One of the crime scene picture obtained by the FOX 5 I-Team shows what appear to be ball bearings or small metal pellets.
The FBI had no comment about the crime scene photos.
The FOX 5 I-Team's sources say these and more pictures have been distributed to key investigators involved in the bomb investigation. Now, agents will identify where all the various components were manufactured, and then sold.
