It's not an Engineer: the Feds would have no reason to want the Engineer since it was only seen to be in relation to A.I. Wash shot the crate, so if an Engineer was in there it would've yelled in pain or died from the shot. In comparison to the Sarcophagus, the crate is too small to carry an Engineer inside.

I also doubt it was an A.I., all of the A.I. fragments were permantely destroyed by the EMP. The only A.I. fragment we've seen since Reconstruction is Epsilon (and his memories of the other fragments).
