A recent New York Post article, about accused Nashville Bomber Anthony Quinn Warner, contained an AP photo that appears to show the remains of the RV he allegedly used in the Nashville explosion. We’ve done a close-up examination of that photo and found some other things as well.

First, the photo above shows that most of the street debris, present in earlier photos, has been removed.

Several men are digging in a shallow crater about six feet wide and 18 inches deep. One fireman is holding a broom, another, wearing tactical headgear is digging inside the small crater. A third, in tactical headgear, is holding an ax with a yellow fiberglass handle. A man in hazmat gear is to their left. Four other men, two with “ATF” prints on their blue helmets’ sides, are standing by as well.

We believe that they are excavating the small crater in search of remains of the explosive device used in the bombing. The men in the tactical gear are likely FBI or ATF Explosive Ordnance Disposal specialists.

After a bombing, an extensive search is made to find any piece of the device for analysis, reconstruction of the detonation mechanism, and testing for chemical residues left by the blast. This small crater is consistent with an explosive device of low destructive power like a volatile gas but not a liquid, which burns, rather than explosively detonates, when ignited.

Next, we looked just above their heads at what appears to be the rear axle assembly of a large truck with two blue buckets in the foreground.

Just to the left of the bucket appear to be a pair of leaf springs of the type used in the Ford Chassis Class C motor homes, the E-350 series. These leaf springs absorb the heavy loads on the rear suspension, in place of shock absorbers, and have a long service life. To the right of the blue bucket appears to be the fractured and scorched case of the rear transaxle. This metal is not very thick, like the axles themselves, which is why it looks scooped out. Further to the right are a brake line and parts of the rear brake assembly.
