I just heard from my sister-in-law and the latest word on my nephew is good. It turned out that although he has a bad staph infection, it is not the drug-resistant strain. They have been able to take him off the morphine pain pump and he should be able to go home on Monday. He will still have to spend a couple of weeks with a pump to drain the wound as it heals, but at least he will be healing.
Thanks for your prayers and however else you helped tip what one friend calls "the galactic scale" in Justin's favor.
