40mi sound of blast and the vehicle used was something big...seems like it may have been an ANFO device...

Easy way to tell. Characteristics of explosives are generally easy to determine, but if it was heard that far away, it's likely a C4 compound. ANFO has a slow-moving blast, so depending on what it sounded like, and what color the cloud was, that can give you really easy clues.

I guess if you can create your own primary explosives nothing's off the table.

If it's anything more than ammonium nitrate and fuel oil I'd be suspicious.

I suppose they could collect blasting caps from damage cars but don't they remove those as they're very expensive.

I'm not even sure that would work but I'm just throwing it out there

There are many different types of homemade explosives.

I am aware

Could be. My uncle is an expert in explosives. (No joke, he’s been an investigator at that in the FBI since I believe 1989).

But it’s a similar vehicle that was used in OKC and WTC. Somewhat similar to Oslo

They should really know about the first world trade center bombing because they're informants compounded the explosives.

And has experience with bombs

If I could see the crime scene more thoroughly I'd know more, if it's a high velocity explosion the vehicle will be practically vaporized, metal frame and all.

True...

Why would they need an RV?

Easier to conceal a large pile of explosives.

Sounds like the dude killed himself 15 minutes prior (or someone else) and then used a bomb to either hide the evidence, or just blow up some 5G garbage.

Easier to conceal and transport a bomb

Either he's dead, or he murdered someone before the blast most likely.

@busillis read Anders Breivek, Ramzi Yousef, and McVeigh. All used ANFO devices and large-ish vehicles

That was my point.

But how did they get the primary explosives

Farming. AN is used in farming. That’s how Breivek attained it in Norway

When I say primary explosive I mean the primer.

Ammonium nitrate is readily available at farm stores

So is sodium nitrate

Urea nitrate

It's what was used in the first world trade center bombing.

I don't think it was a huge amount, if I'd have to guess maybe 50-100kg at most.

Urea can be easily obtained from diesel exhaust fluid...

But AN is highly volatile

It's 35% of the mixture.

Or maybe he was making acetone peroxide on site?

Somebody blew a joggers leg off in New York City a while back with the above compound.

....


The most common route for nearly pure TATP is H2O2/acetone/HCl in 1:1:0.25 molar ratios, using 30% hydrogen peroxide.

Naw, the explosive had a delay, that's pretty telling with ANFO devices.

Due to use of fuses.

(Primarily, there are some that use blasting caps, but I doubt this did, was too delayed.)

How did he get the blasting caps?
