I'm not sure evidence supports that as an only conclusion.
Without suggesting that this is in any way validated by the picture, IF an aircraft were to (for whatever reason) exceed its demonstrated dive speed and be subject as a result to aeroelastic instability (flutter) of the wing I can imagine all kinds of unusual and extreme loads being applied to parts of the wings. Only someone who knows exactly what damage that part has and also what it would be subject to under various scenarios can identify the most likely cause.
