Based on the new information that has come to light, is it still prudent to even blog about this event? If so, would it not be better to re-write this story altogether.

Personally, I threw in the towel in January, but management gave him this opportunity. If you wish to take away this opportunity on the basis of this last incident, (considering all mitigation), I think it's a mistake.
Just my opinion.
