I will try to translate as precisely as I can what this man said.

and go to +12'
"We are expecting a lot from this study because it will allow us to understand by the shape of the debris, by the cuts and possibly marks of burn what happened."
In this context "éventuellement " may be translated by "perhaps".
The France3 network also covered the same event on the same day and interviewed the very same person. And he said almost exactly the same thing:
Journaux télévisés en vidéo - France 3
and go to +15'45''
