We should watch for the condition of the railing.  If the rocket hit with side velocity and slid/tumbled off, then the railing will be visibly damaged.
Looking at the last seconds of flight, the vehicle orientation looks off. Possibly due to a hydraulics out. Possibly accounting for a skid. We'll have to see. Nice though that this most likely dissproves a massive explosion.

Appears there is something is on the deck.

This image is from the edge of the atmosphere, at approx T+7m, during the re-entry burn.  It's an amazing image IMO.

Good to know. I can only hope to get a view of the railing.

Reports about some wreckage on the barge, we are quite hopeful there will be images in a short while.

On APM terminal pic it does looks like something is on deck.

It makes the most sense that EIII is always towing, and GM is assisting from behind. 

It's possible that GM, being a local pilot, is in command - and has the freedom to disengage and push from other directions if necessary.

Yes, I always assumed the GM was basically steering the barge, rather than just there to push.  I guess they can't use the thruster pods in the river.

Anyway, deck looked empty to me.
If you've already eliminated hardware failure as a cause for the unsuccessful landing, what would be the value in bringing back the pieces?  It'll be simpler to just dispose of them at sea after taking some pictures -- with the added advantage that there won't be pictures of the barge coming into port with pieces of a "failure" (even though we know it wasn't).

There would be valuable data to be obtained from the condition of the engines if you could recover them... they should be able to tell the difference between crash damage and operational wear during a teardown.

Taking apart hardware that survived and which actually flew through an actual launch environment to check whether it held up as expected? You know, post-flight inspection for lessons learned, near-misses and potential other funnies in the data?

Here is the video I captured from the webcam (the online player seems to playback at 360p only, but you can download the video to get the full resolution), hopefully it's useful to someone: https://drive.google.com/file/d/0B23z_72hplPtMEp5X1ZsMnhfWDg/view?usp=sharing

So a diesel-powered hydraulic power unit for a Thrustmaster is toast, as is the cherry picker it looks like.
Remembering those who made the ultimate sacrifice for our rights & freedoms, and for those injured, visible or otherwise, in that fight.

Looks like they have got some pieces covered up on deck.

Amazing photos by /u/relevant__comment over on reddit:
