Larry Pichon called an ambulance to take his wife, Judy, to a hospital in Lake Charles, in southwest Louisiana, on the morning of July 13. He'd had to do this before.
She had a rare autoimmune disease — granulomatosis with polyangiitis, which causes inflammation of blood vessels and can be particularly damaging for the lungs and kidneys. It wasn't uncommon for Judy to make a trip to the emergency room.
"When she got in the ambulance to go was the last time I saw her, and that was around nine o'clock," Larry remembered.
