I can tell you for a fact unless the parents consented to organ donation nothing was harvested.
You're preaching to the choir, I know this.
I also know (from personal experience...) that long before the plug was actually pulled, organ recipients were lined up and advised to be ready to head to the hospital as soon as the organ harvest began.
That's just how organ donation works. As soon as a viable donor is found, blood match work and other processes are performed and then cross-matched against a nationwide database of people on the organ recipient network so that when the organs are harvested, the recipients are in-hospital and prepped for transplant.
