I just got word from former co-workers that this may have been one of my former project managers. (39 year old). If it is the same accident, then as I have been informed, the older rider tried to pass a cage on a turn and crossed the centre line into the path of the 39yr old's bike, going the opposite way. Younger rider got on the brakes and the bike apparently started to highside and the older rider ended up T-boning the younger. (Only using the older/younger terms for reference to bike A and bike B btw). Younger rider (my former workmate is in hospital with several cracked ribs, a shattered left arm and numerous other injuries, but is out of the woods. Not sure on the final outcome or of the condition of the older rider.
Again, this is not for certain that this is the incident I was informed of but the time frame and similarities all fit.
