Looks like the spark plug ground electrode was hit also so my guess is the piston came up too far.

Something got down the intake and ended up on top of the piston. Nut, bolt, wrench, piece of the intake and/or turbo?

discoloration on the chamber, a plug that is showing lean condition and what looks to be EX valve tagging? High rev valve float?
Do I win?

I'm going with snapped connecting rod - it appears piston hit the 2 exhaust valves, based on discoloration on bottom of them closest to plug.
