I have a little SFA experience and in my opinion, the red arrows show where the break started. This would appear to be right at the edge of the machined journal. Seems to be some heat scoring marks on the journal itself (dark lines), possibly from an increase in bearing temps? Those wouldn't have happened after the break because the engine would have stopped rotating almost instantly given the carnage.
Terrible situation Eljaro.
EDIT>> What balancer is that you were running? Fluid or SFI?
