What strikes me as odd is that this looks like the "naked" engine, without the cowling/nacelle that usually surrounds it? Anyway, if an engine departs the aircraft shortly after (last-minute) maintenance was performed on it, that's indeed suspicious...
The fan cowl and thrust reverser cowl are structurally fastened to the pylon/strut at the top, they only wrap around the engine, and are fastened to themselves at the bottom using latches. The strut considered part of the airframe structure. The inlet cowl is bolted directly to the engine, I saw in a picture that it was found approximately mid-field on the airport property.
