The debris field is quite large which suggests a glancing impact as opposed to "head on".
The right side cylinder heads / valve covers show damage while the left side shows no apparent damage in the photo.
One photo shows wreakage caught in a tree.
Looks like CFIT.
Perhaps an aerobatic maneuver gone wrong and/or entered too low? At 10,000' we have higher TAS and increased radii for turns and pullouts.
