The FBI reported the backpack had to be destroyed later to be made safe after an X-ray showed a meter device and tools.
Found at the blast site were a chemistry book, a crescent wrench, a white sock with at least two protruding wires, a screwdriver with a sock stuffed in the handle, a large number of unused wooden matches, and an empty match box, the records show.
Also found was a pen with an attached razor and a nine-volt battery. Behind the bench was a black plastic container with "Cross Country" and "lubricant" on the label. On the bench was a pink pen with two protruding wires and on the sidewalk was a green circuit board.
The student's father, Joel Hinrichs Jr., said again Friday his son intended to kill only himself. He is still waiting for the release of his son's remains, after DNA testing is completed. He plans to cremate the body.
The father, who was shown photos of his son's body by the FBI, said, "He sat there on the bench with one arm wrapped around the explosive looped around his neck and the other hand holding some kind of device to make it go off."
"a cloud of gray smoke as well as a human arm."
"one arm wrapped around the explosive looped around his neck and the other hand holding some kind of device to make it go off."
Did he have 3 arms?
The explosive was looped around his neck? Was he trying to set it off? Was he trying to move it out of his backpack and under his clothing to conceal it better, and try to get it into the stadium, and it went off by accident? Or was the bomb someone else's idea, he was trying to get it off or disarm it, and it went off (either by accident or remote detonation)?
The first time I read the above paragraph from the article, my thought was "The FBI had photos of him hunched on the park bench? From where?" Then I figured they were talking about after-explosion photos of what was left of the body
