I wonder who inputed the wrong take-off weight? The captain or first officer?

I wonder who inputed the wrong take-off weight? The captain or first officer?

I think there were tight lips on this one. The accident investigation says this:

While reviewing the aircraft’s performance documentation in preparation for landing, the crew noticed that a take-off weight, which was 100 tonnes below the actual take-off weight of the aircraft, had inadvertently been used when completing the take-off performance calculation. The result of that incorrect take-off weight was to produce a thrust setting and take-off reference speeds that were lower than those required for the aircraft’s actual weight.

BTW, a LOT more data, info, pics of the interior damage to the aircraft here:
