Hard to say the cause, from my observation:

Notice the debris field at 57 seconds on the NBC coverage, is to the passenger side of the vehicle, after it struck the tree.

The kinetic motion of the vehicle would normally cause parts of the vehicle to be projected forward of the vehicle after it struck an object.

Therefore that debris field was caused by the explosion. Obviously the explosion did not take place immediately at the time of impact, but at an unknown quantity of time thereafter.

Very suspicious in my opinion. He obviously was a good friend of Chris Hayes, Rachel Maddow and Jeremy Scahill based on his tweets. Scahill is behind the movie "Dirty Wars", definitely on my top ten 'want to see' list.

Rest in Peace Michael Hastings, G_d be with you.
